74ABT16646 Datasheet 16-bit Bus Transceiver/register

Manufacturer: NXP Semiconductors

Overview: INTEGRATED CIRCUITS 74ABT16646 74ABTH16646 16-bit bus transceiver/register (3-State) Product specification Supersedes data of 1995 Aug 17 IC23 Data Handbook 1998 Feb 27 Philips Semiconductors Philips Semiconductors.

General Description

The 74ABT16646 high–performance BiCMOS device bines low static and dynamic power dissipation with high speed and high output drive.

The 74ABT16646 16-bit transceiver/register consists of two sets 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 from the internal registers.

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

Key Features

  • Independent registers for A and B buses.
  • Multiple VCC and GND pins minimize switching noise.
  • Live insertion/extraction permitted.
  • Power.
  • up 3-State.
  • Power.
  • up reset.
  • Multiplexed real-time and stored data.
  • Outputs sink 64mA and source 32mA.
  • Latch.
  • up protection exceeds 500mA per JEDEC Std 17.
  • 74ABTH16646 incorporates bus-hold data inputs which eliminate the need for external pull-up resistors t.
