CMOS Logic ◆CMOS Schmitt Trigger Inverter ■Applications ◆High Speed Operation ●Palmtops : tpd=2.3ns TYP ●Digital Equipment ◆Operating Voltage Range : 2V~5.5V ◆Low Power Consumption : 1µA (max) ■General Description ■Features The XC74UL14AA is a CMOS Schmitt Trigger Inverter, manufactured using silicon gate CMOS fabrication. CMOS low power circuit operation makes high speed LS-TTL operations achievable. With a wave forming buffer connected internally, stabilized output can be achieved as the circuit offers high noise immunity. As the XC74UL14AA is integrated into mini molded, SSOT-25 and SOT25 packages, high density mounting is possible.
