74LCXZ16245 Low Voltage 16-Bit Bidirectional Transceiver with 5V Tolerant Inputs and Outputs
March 2002
Revised March 2002
74LCXZ16245
Low Voltage 16-Bit Bidirectional Transceiver
with 5V Tolerant Inputs and Outputs
General Description
The LCXZ16245 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 (2.7V 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.
When V
CC
is between 0V and 1.5V, the LCXZ16245 is on
the high impedance state during power-up or power-down.
This places the outputs in the high impedance (Z) state
preventing intermittent low impedance loading or glitching
in bus oriented applications.
The LCXZ16245 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.

Note 1:
To ensure the high-impedance state during power up or down, OE
should be tied to V
CC
through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.
