74F652A Datasheet Transceivers/registers

Manufacturer: Philips Semiconductors (now NXP Semiconductors)

Overview: INTEGRATED CIRCUITS 74F651A/74F652A Transceivers/registers Product specification Replaces datasheet 74F651/74F652/74F651A/74F652A of 1990 Oct 23 1999 Jun 23 IC15 Data Handbook Philips Semiconductors Philips.

General Description

The 74F651A and 74F652A 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

  • 74F651A/74F652A.
  • Combines 74F245 and two 74F374 type functions in one chip.
  • High impedance base inputs for reduced loading (70µA in high and low states).
