General description

The 74ABT821 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.

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
