The SN74LVC1G32DBVR is a single-pole double-throw (SPDT) logic device designed with bus-hold logic circuitry. This logic device is designed to provide a logic level signal in response to two different logic inputs and can function as either a two-input OR gate or a two-input NOR gate. This makes the SN74LVC1G32DBVR an ideal choice for applications requiring two different logic signals, such as data transfer, combination or conversion between two different voltage levels.

Overview

The SN74LVC1G32DBVR is a low voltage, low power logic device manufactured by Texas Instruments. It is an enhanced version of Texas Instruments\' original SN74LVC1G32DBVR device and features a low input gate-level voltage of 0.8 volts, allowing it to accept a wide range of logic inputs. It also features a very low on-capacitance (<4pf), making it ideal for driving higher capacitance loads, such as FPGAs, ASICs and other digital integrated circuits. Although the SN74LVC1G32DBVR is a single-pole, double-throw device, it can be used to create a two-input OR or NOR gates by connecting one of the inputs to GND or Vcc.

Application Field

The SN74LVC1G32DBVR is an ideal choice for a wide range of logic applications, including data transfer, combination or conversion between two different logic signals. These logic signals can be at different voltage levels, making the device suitable for low-voltage (2.0V to 3.6V) or A-grade (2.7V to 3.6V) applications. Additionally, the low-power architecture and low-operating voltage allows the SN74LVC1G32DBVR to draw significantly low power, making it suitable for low-power automotive and LED lighting applications.

Working Principle

The SN74LVC1G32DBVR is a single-pole, double-throw device with two inputs and two outputs. The two inputs are referred to as A and B, while the two outputs are referred to as Y and Z. When A is low, the device passes the logic level from B to Y, and when A is high, the device passes the logic level from B to Z. If both inputs are low, the device output is unknown and may be unstable. The SN74LVC1G32DBVR uses a bus-hold logic architecture, thus, if one of the inputs is left open, the last logic level applied to the device will be held at the output.

Conclusion

The SN74LVC1G32DBVR is a low voltage, low power logic device designed to provide a logic level signal in response to two different logic inputs and can function as either a two-input OR gate or a two-input NOR gate. It is ideal for a wide range of logic applications, including data transfer, combination or conversion between different voltage levels. The device uses a bus-hold logic architecture, thus, if one of the inputs is left open, the last logic level applied to the device will be held at the output.
