Description

The M54HCxxx and M54HCTxxx series are composed of over 90 types of high speed CMOS functions specifically designed to meet the radiation requirements of the aerospace industry. It includes a large set of gates, Flip-Flops, Multiplexers, Counters, Bus interface and several other functions. The radiation hardness, the single event latch-up (SEL) immunity and the housing in hermetic packages of all types of both series make them ideally suited for use in the most difficult environmental conditions.

Features

■ 2 to 6 V operating voltage

■ Low power DC dissipation: 1 μA max at 25°C

■ High speed tPD = 8 ns typ at 25°C

■ Symmetrical outputs characteristics

■ High noise immunity: 28 of min VCC

■ Hermetic packages

■ Rad-hard 50 krad (Si)
