74ABTH16821A Datasheet 20-bit Bus-interface D-type Flip-flop

Manufacturer: NXP Semiconductors

Overview: INTEGRATED CIRCUITS www.DataSheet4U.net 74ABT16821A 74ABTH16821A 20-bit bus-interface D-type flip-flop; positive-edge trigger (3-State) Product specification Supersedes data of 1995 Sep 28 IC23 Data Handbook 1998 Feb 27.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The 74ABT16821A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.

The 74ABT16821A has two 10-bit, edge triggered registers, with each register coupled to a 3-State output buffer.

The two sections of each register are controlled independently by the clock (nCP) and Output Enable (nOE) control gates.

Key Features

  • 20-bit positive-edge triggered register.
  • Multiple VCC and GND pins minimize switching noise.
  • Live insertion/extraction permitted.
  • Power-up reset.
  • Power-up 3-State.
  • 74ABTH16821A incorporates bus-hold data inputs which eliminate the need for external pull-up resistors to hold unused inputs.
