74ALS651 Datasheet Transceiver/register

Manufacturer: NXP Semiconductors

Overview: INTEGRATED CIRCUITS 74ALS651/74ALS651–1 74ALS652/74ALS652–1 Transceiver/register Product specification IC05 Data Handbook Philips Semiconductors 1991 Feb 08 Philips Semiconductors Product specification.

General Description

The 74LAS651 and 74ALS652 transceivers/registers consist of bus transceiver circuits with 3-State outputs, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or the internal registers.

Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes High.

Output enable (OEAB, OEBA) and select (SAB, SBA) pins are provided for bus management.

Key Features

  • Independent registers for A and B buses.
  • Multiplexed real-time and stored data.
  • Choice of non-inverting and inverting data paths.
  • 3-State outputs.
  • The -1 versions sinks 48mA IOL within the ±5% VCC range.
