74ABTH16899 - 18-bit latched transceiver

Download the 74ABTH16899 datasheet PDF. This datasheet also covers the 74ABTH variant, as both devices belong to the same 18-bit latched transceiver family and are provided as variant models within a single manufacturer datasheet.

General Description

The 74ABT/H16899 has three principal modes of operation which are outlined below.

All modes apply to both the A-to-B and B-to-A directions.

Key Features

  • Symmetrical (A and B bus functions are identical).
  • Selectable generate parity or ”feed-through” parity for A-to-B and B-to-A directions Parity error checking of the A and B bus latches is continuously provided with ERRA and ERRB, even with both buses in 3-State. The 74ABT/H16899 features independent latch enables for the A and B bus latches, a select pin for ODD/EVEN parity, and separate error signal output pins for checking parity.
  • Independent transparent latches.
