9-bit D-type flip-flop with reset and enable; 3-state

Rev. 03 — 23 March 2010

Product data sheet

1. General description

The 74ABT823 high-performance BiCMOS device combines low static and dynamic

power dissipation with high speed and high output drive.

The 74ABT823 is a 9-bit wide buffered register with clock enable input (CE) and master

reset input (MR) which are ideal for parity bus interfacing in systems using many

microprocessors.

The 74ABT823 is designed to eliminate the extra packages required to buffer existing

registers and provide extra data width for wider data and address paths of buses carrying

parity.

The 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 output Q of the flip-flop.

2. Features and benefits

„ High-speed parallel registers with positive edge-triggered D-type flip-flops

„ Ideal where high speed, light loading, or increased fan-in are required with MOS

microprocessors

„ Output capability: +64 mA and −32 mA

„ Power-on 3-state

„ Power-on reset

„ Latch-up protection exceeds 500 mA per JESD78B class II level A

„ ESD protection:

‹ HBM JESD22-A114F exceeds 2000 V

‹ MM JESD22-A115-A exceeds 200 V
