74ABT16821A

20-bit bus-interface D-type flip-flop; positive-edge trigger;

3-state

Rev. 03 — 16 March 2010

Product data sheet

1. 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.

Each register is fully edge triggered. The state of each D input, one set-up time before the

LOW-to-HIGH clock transition, is transferred to the corresponding flip-flops Q output.

The 3-state output buffers are designed to drive heavily loaded 3-state buses, MOS

memories, or MOS microprocessors.

The active-LOW output enable (nOE) controls all ten 3-state buffers independent of the

When nOE is HIGH, the outputs are in high-impedance OFF-state, which means they will

neither drive nor load the bus.

2. Features and benefits
