CMOS Logic ◆CMOS 2-Input OR Gate ◆High Speed Operation ■Applications : tpd=3.8ns TYP ●Palmtops ●Digital Equipment ◆Operating Voltage Range : 2V~5.5V ◆Low Power Consumption : 1µA (max) ■General Description ■Features The XC74UL32AA is a 2-input CMOS OR gate, 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 XC74UL32AA is integrated into mini molded, SSOT-25 and SOT25 packages, high density mounting is possible.
