General Description

The LCX543 is a non-inverting octal transceiver containing two sets of D-type registers for temporary storage of data flowing in either direction.

Separate Latch Enable and Output Enable inputs are provided for each register to permit independent input and output control in either direction of data flow.

The LCX543 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment.
