UT54ACS132

UT54ACS132/UT54ACTS132 Radiation-Hardened Quadruple 2-Input NAND Schmitt Triggers Dec. 1, 2003 FEATURES 1.2µ radiation-hardened CMOS (ACTS 132) and 0.6µ CRH CMOS process (ACS132) - Latchup immune High speed www.DataSheet4U.com Low power consumption Single 5 volt supply Available QML Q or V processes Flexible package - 14-pin DIP (not available for the ACS132) - 14-lead flatpack DESCRIPTION The UT54ACS132 and the UT54ACTS132 are 2-input NAND gates with Schmitt Trigger input levels. A high applied on both the inputs forces the output to a low state. The devices are characterized over full military temperature range of -55°C to +125°C.
