The XC74ULU04A is a CMOS Inverter, manufactured using silicon gate CMOS fabrication. CMOS low power circuit operation makes high speed LS-TTL operation achievable. The internal circuit is composed of a single stage inverter, so can be used in the crystal oscillator. As the XC74ULU04A is integrated into mini molded, SSOT-25 and SON-6 packages, high density mounting is possible.
