描述 Description

The LEOAC74 is a CMOS Dual D-type positive edge-triggered flip-flop for use in

aerospace environments. It operates from 2 V to 6 V power supply (7 V absolute

maximum rating).

The LEOAC74 can operate over a large temperature range of -40 °C to +125 °C and

it is housed in plastic TSSOP-20, Thin-Shrink Small Outline Package, 20 leads, using

golden bonding and Nickel/Palladium/Golden-lead-finishing to prevent whiskers.

The LEOAC74 is compliant with ST-LEO-specification, dedicated specification for

space-ready rad-hard plastic products. This AEC-Q100-based specification offers

a specific trade-off between footprint size savings, cost of ownership and quality

assurance together with radiation hardness and large quantity capability.

Applications

• Low earth orbit (LEO) applications
