74LCX32245 Low Voltage 32-Bit Bidirectional Transceiver with 5V Tolerant Inputs and Outputs
November 2001
Revised June 2002
74LCX32245
Low Voltage 32-Bit Bidirectional Transceiver
with 5V Tolerant Inputs and Outputs
General Description
The LCX32245 contains thirty-two non-inverting bidirec-
tional buffers with 3-STATE outputs and is intended for bus
oriented applications. The device is designed for low volt-
age (2.5V or 3.3V) V
CC
applications with capability of inter-
facing to a 5V signal environment. The device is byte
controlled. Each byte has separate control inputs which
could be shorted together for full 32-bit operation. The T/R
inputs determine the direction of data flow through the
device. The OE inputs disable both the A and B ports by
placing them in a high impedance state.
The LCX32245 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
