74LCX16245
Low Voltage 16-Bit Bidirectional Transceiver
with 5V Tolerant Inputs and Outputs
General Description
The LCX16245 contains sixteen non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus oriented
applications. The device is designed for low voltage
(2.5V or 3.3V) VCC applications with capability of interfacing
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.
The LCX16245 is fabricated with an advanced CMOS technology
to achieve high speed operation while maintaining
CMOS low power dissipation.
Features

Note 1: To ensure the high-impedance state during power up or down, OE
should be tied to VCC through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.
Ordering Code:
Note 2: Ordering code “G” indicates Trays.
Note 3: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
