74ALVC16245
Low Voltage 16-Bit Bidirectional Transceiver
with 3.6V Tolerant Inputs and Outputs
General Description
The ALVC16245 contains sixteen non-inverting bidirec-
tional buffers with 3-STATE outputs and is intended for bus
oriented applications. The device is byte controlled. Each
byte has separate 3-STATE control inputs which can 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.
The 74ALVC16245 is designed for low voltage (1.65V to
3.6V) V
CC
applications with I/O compatibility up to 3.6V.
The 74ALVC16245 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
