Description
The LEOAC244 is a CMOS low power octal bus buffer 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 3-state non-inverted output.
The LEOAC244 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 gold-wires and nickel/palladium/golden-lead-finishing to prevent from whiskers.
The LEOAC244 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
