74LCX16245TTR

具有5V容限输入和输出低电压CMOS 16位总线收发器（ 3 -STATE ） LOW VOLTAGE CMOS 16-BIT BUS TRANSCEIVER WITH 5V TOLERANT INPUTS AND OUTPUT 3-STATE

DESCRIPTION

The 74LCX16245 is a low voltage CMOS 16 BITBUS TRANSCEIVER 3-STATE fabricated with

sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power

and high speed 3.3V applications; it can be interfaced to 5V signal environment for both inputs

and outputs.

This IC is intended for two-way asynchronous communication between data buses; the direction

of data transmission is determined by DIR input. The two enable inputs nG can be used to disable

the device so that the buses are effectively isolated.
