74LCXR162245
Low Voltage 16-Bit Bidirectional Transceiver
with 5V Tolerant Inputs/Outputs
and 26 Series Resistors in the Outputs
General Description
The LCXR162245 contains sixteen 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 16-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.
In addition, all A and B outputs include equivalent 26
:
(nominal) series resistors to reduce overshoot and under-
shoot and are designed to sink/source up to 12 mA at
V
CC
3.0V.
The LCXR162245 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
