M74HC21规格书详情
描述 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.
特性 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)
■ SEL immune up to 110 MeV/mg/cm²
