LEOAC74 Datasheet Rad-hard plastic Dual D-type positive edge-triggered flip-flop Maturity status link LEOAC74 Features Dual D-type positive edge-triggered flip-flop 6 V max. operating 7 V max. rating 8.5 ns propagation delay Nickel/Palladium/Gold-lead-finished (NiPdAu), whisker-free Gold-wires RML <1% and CVCM <0.1% guaranteed outgassing 50 krad (Si) Total Ionizing Dose SEL-free up to 62.5 MeV.cm²/mg Mass: 80 mg Compliant with ST-LEO-specification Applications Low earth orbit (LEO) applications 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.
