The part number "SN74LVC1G07DBVR" is from Texas Instruments (TI), a well-known global semiconductor company.
This specific part is a single buffer with an open-drain output, typically used for voltage level translation, logic-level interfacing, and in applications requiring open-drain outputs. It's part of the LVC (Low Voltage CMOS) family, meaning it operates at lower voltages while still providing the benefits of CMOS technology, such as low power consumption.
Package Type and Pin Configuration
The "DBVR" suffix corresponds to the SOT-23-5 package type, which is a small, 5-pin surface-mount package.
Pinout (5 pins): Pin No. Pin Name Description 1 A Input (logic signal) 2 GND Ground (0V) 3 Vcc Supply Voltage (Typically 2.7V to 5.5V) 4 Y Output (open-drain) 5 NC No Connect (reserved or not used)Pin Function Explanation
Pin 1 (A): This is the input pin where the logic signal is applied. This pin accepts standard logic levels. Pin 2 (GND): Ground pin, which should be connected to the system's ground (0V) to complete the circuit. Pin 3 (Vcc): This is the supply voltage pin. The chip is designed to operate with a voltage in the range of 2.7V to 5.5V, and the actual voltage level is typically set according to the needs of the connected logic circuits. Pin 4 (Y): The open-drain output pin. When the input signal on Pin 1 is active, this output will either drive low (to ground) or be in a high-impedance state (which means it is effectively disconnected, and a pull-up resistor is required for logic high). Pin 5 (NC): This is a "No Connect" pin, meaning it is not internally connected to any circuitry inside the chip and can be left unconnected.FAQ: Frequently Asked Questions (20)
Q: What is the operating voltage range for the SN74LVC1G07DBVR? A: The SN74LVC1G07DBVR operates within a voltage range of 2.7V to 5.5V.
Q: What is the maximum current that can be sourced from the output pin (Y)? A: The output pin (Y) is an open-drain configuration, so it cannot source current. It can only pull low or be in a high-impedance state, requiring an external pull-up resistor to pull the output high.
Q: Can the SN74LVC1G07DBVR be used for voltage level translation? A: Yes, this part is often used in voltage level translation applications, where it can interface different logic levels between devices.
Q: How should the input pin (A) be driven? A: The input pin (A) should be driven with standard logic signals (low or high voltage levels based on the Vcc supplied).
Q: What is the significance of the No Connect (NC) pin? A: The NC pin does not have an internal connection and is typically not used in the circuit.
Q: Can the SN74LVC1G07DBVR be used in a 5V system? A: Yes, it can operate in a system where 5V is the supply voltage, as it supports a maximum of 5.5V.
Q: What kind of output does the SN74LVC1G07DBVR have? A: The output is open-drain, meaning it can only pull the output low or leave it floating, requiring an external pull-up resistor to drive a logic high.
Q: What package is the SN74LVC1G07DBVR available in? A: The SN74LVC1G07DBVR is available in a 5-pin SOT-23-5 surface-mount package.
Q: How do I use the SN74LVC1G07DBVR in a logic circuit? A: You apply a logic signal to the input pin (A), and the open-drain output pin (Y) will either pull low or stay in a high-impedance state depending on the input.
Q: Does the SN74LVC1G07DBVR require a pull-up resistor on the output pin? A: Yes, since the output pin is open-drain, a pull-up resistor is required to ensure that the output can go high when needed.
Q: What is the function of the ground (GND) pin on the SN74LVC1G07DBVR? A: The GND pin is used to connect the chip's ground reference to the system ground.
Q: Can the SN74LVC1G07DBVR be used in high-speed applications? A: Yes, it is suitable for high-speed logic interfacing due to its low voltage CMOS technology, providing fast switching speeds.
Q: Is the SN74LVC1G07DBVR compatible with TTL logic levels? A: Yes, it is compatible with TTL logic levels as it can accept both CMOS and TTL input signals.
Q: What is the maximum output sink current for the SN74LVC1G07DBVR? A: The maximum sink current for the output pin is 20mA.
Q: What is the typical input capacitance of the SN74LVC1G07DBVR? A: The typical input capacitance is around 4pF.
Q: How does the open-drain output work in the SN74LVC1G07DBVR? A: The open-drain output can only pull low or be in a high-impedance state. When driving high, the pull-up resistor pulls the output to the supply voltage.
Q: Can the SN74LVC1G07DBVR be used for logic signals greater than 5.5V? A: No, the device should not be exposed to voltages greater than 5.5V as it could damage the internal circuitry.
Q: What kind of applications is the SN74LVC1G07DBVR used in? A: It is used in logic-level translation, interfacing different voltage levels, and systems requiring open-drain outputs for bus communication.
Q: Is there an overvoltage protection on the input of the SN74LVC1G07DBVR? A: No, there is no overvoltage protection, so the input voltage should be within the specified logic levels for reliable operation.
Q: How does the SN74LVC1G07DBVR behave when the input is left floating? A: It is not recommended to leave the input floating. The input should always be tied to a defined logic level (either high or low).
