74LCX245 Low Voltage Bidirectional Transceiver with 5V Tolerant Inputs and Outputs
February 1994
Revised March 2005
74LCX245
Low Voltage Bidirectional Transceiver
with 5V Tolerant Inputs and Outputs
General Description
The LCX245 contains eight non-inverting bidirectional buff-
ers with 3-STATE outputs and is intended for bus oriented
applications. The device is designed for low voltage (2.5V
and 3.3V) V
CC
applications with capability of interfacing to
a 5V signal environment. The T/R input determines the
direction of data flow through the device. The OE input dis-
ables both the A and B ports by placing them in a high
impedance state.
The LCX245 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
