3 Description

The SN74LVC1G57B-Q1 device features configurable multiple functions. The output state is determined by eight patterns of 3-bit input. The user can select the logic functions AND, OR, NAND, NOR, XNOR, inverter, and buffer. All inputs can be connected to VCC or GND. SN74LVC1G57B-Q1 functions as two independent buffers, but because of Schmitt action, the device can have different input threshold levels for positive-going (VT+) and negative-going (VT–) signals.
