Manufacturer: Texas Instruments

General Description

74AC11651 OCTAL BUS TRANSCEIVER AND REGISTER WITH 3ĆSTATE OUTPUTS SCAS135 − MARCH 1990 − REVISED APRIL 1993 DW OR NT PACKAGE (TOP VIEW) OEAB A1 A2 A3 A4 GND GND GND GND A5 A6 A7 A8 OEBA 1 2 3 4 5 6 7 8 9 10 11 12 13 14 28 CLKAB 27 SAB 26 B1 25 B2 24 B3 23 B4 22 VCC 21 VCC 20 B5 19 B6 18 B7 17 B8 16 CLKBA 15 SBA These devices consist of bus transceiver circuits, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the data bus or from the internal storage registers.

Output-enable (OEAB and OEBA) inputs are provided to control the transceiver functions.

The select-control (SAB and SBA) inputs are provided to select whether real-time or stored data is transferred.

Overview

• Independent Registers and Enables for A and B Buses • Multiplexed Real-Time and Stored Data • Inverting Data Paths • Flow-Through Architecture Optimizes PCB Layout • Center-Pin VCC and GND Configurations Minimize.
