Description

The 74LVTH543 octal transceiver contains two sets of D-type latches for temporary storage of data flowing in either direction. Separate Latch Enable and Output Enable inputs are provided for each register to permit independent control of inputting and outputting in either direction of data flow.

The 74LVTH543 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.

This octal registered transceiver is designed for low-voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The 74LVTH543 is fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation.
