Description

The LEOAC14 is a CMOS low power hex inverter qualified for use in aerospace

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

ratings). Each operator features a Schmitt trigger input that is capable of transforming

slowly changing input signals into sharp output signals.

The LEOAC14 can operate over a large temperature range of -40 °C to +125 °C and

it is housed in a plastic TSSOP-20, thin-shrink small outline package, 20 leads, using

gold-wires and nickel/palladium/golden-lead-finishing to prevent whiskers.

The LEOAC14 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.
