Product overview
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 a 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.
