STMicroelectronics LEOAC08
The LEOAC08 is a CMOS low power quad 2-input AND gate qualified for use in aerospace environments. It operates from 1.65 V to 6 V power supply (7 V absolute maximum rating). The LEOAC08 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.FEATURES
