15.11.4. Pinning
15.12. 74LCX245
15.12.1. General Description
The LCX245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and
is intended for bus oriented applications. The device is designed for low voltage (2.5V
and 3.3V) VCC 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
disables both the A and B ports by placing them in a high impedance state.
The LCX245 is fabricated with an advanced CMOS technology to achieve high speed
operation while maintaining CMOS low power dissipation.
