SCES414P November 2002 – November 2016 SN74LVC1G57
The SN74LVC1G57 device features configurable multiple functions. The output state is determined by eight patterns of 3-bit input. The user can choose the logic functions AND, OR, NAND, NOR, XNOR, inverter, and buffer. All inputs can be connected to VCC or GND.
The CMOS device has high output drive while maintaining low static power dissipation over a broad VCC operating range.
This configurable multiple-function gate is designed for 1.65-V to 5.5-V VCC operation.
Schmitt-trigger inputs are designed to provide a minimum separation between positive and negative switching thresholds. This allows for noisy or slow inputs that would cause problems such as oscillation or excessive current draw with normal CMOS inputs
The SN74LVC1G57 is a configurable multiple-function gate is designed for 1.65-V to 5.5-V VCC operation. Inputs are over-voltage tolerant up to 5.5 V. This feature allows the use of this device as a translator in a mixed 1.8-V, 3.3-V, and 5-V system environment.
