Description
The LEOAC32 is a CMOS low power quad 2-input OR gate qualified for use in
aerospace environments. It operates from a 2 V to 6 V power supply (7 V absolute
maximum rating).
The LEOAC32 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 LEOAC32 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.
