74LVC1G57
Low-power con鏗乬urable multiple function gate
Rev. 01 鈥?6 September 2004
Product data sheet
1. General description
The 74LVC1G57 is a high-performance, low-power, low-voltage, Si-gate CMOS device,
superior to most advanced CMOS compatible TTL families.
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of this
device in a mixed 3.3 V and 5 V environment.
This device is fully speci鏗乪d for partial power-down applications using I
off
. The I
off
circuitry
disables the output, preventing the damaging back鏗俹w current through the device when it
is powered down.
The 74LVC1G57 provides con鏗乬urable 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 V
CC
or GND.
All inputs (A, B and C) have Schmitt-trigger action. They are capable of transforming
slowly changing input signals into sharply de鏗乶ed, jitter-free output signals.
