| x CMOS Schmitt Trigger Inverter x High Speed Operation tpd=12ns TYP x Operating Voltage Range 2V~6V x Low Power Consumption 1A MAX s Applications q Palmtops q Digital Equipment s General Description The XC74UH14AAM is a CMOS Schmitt Trigger Inverter, manufactured using silicon gate CMOS fabrication. CMOS low power circuit operation makes high speed LS-TTL operations achieveable. With a wave forming buffer connected internally, stabilized output can be achieved as the circuit offers high noise immunity. As the XC74UH14AAM is integrated into a mini molded, SOT-25 package, high density mounting is possible. s Features High Speed Operation: tpd=12ns TYP Operating Voltage Range: 2V~6V Low Power Consumption: 1A MAX Space Saving Package: SOT-25 s Pin Configuration NC 1 5 VCC s Function INPUT A H L OUTPUT Y L H A 2 H=High level, L=Low level 4 Y o GND 3 SOT-25 (TOP VIEW) s Absolute Maximum Ratings PARAMETER Power Supply Voltage Input Voltage Output Voltage Input Diode Current Output Diode Current Output Current VCC ,GND Current Continuous Total Power Dissipation Storage Temperature Note: Voltage is all Ground standardized.
