MM54HC4075/MM74HC4075 Triple 3-Input OR Gate General Description These OR gates utilize advanced silicon-gate CMOS technology to achieve operating speeds similar to LS-TTL gates with the low power consumption of standard CMOS integrated circuits. All gates have buffered outputs, providing high noise immunity and the ability to drive 10 LS-TTL loads. The 54HC/74HC logic family is functionally as well as pinout compatible with the standard 54LS/74LS logic family. The 54HC4075/74HC4075 is functionally equivalent and pin-out compatible with the CD4075B and MC14075B metal gate CMOS devices. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground. Features Y Typical propagation delay: 11 ns Y Wide power supply range: 2V±6V Y Low quiescent current: 20 mA maximum (74HC Series) Y Low input current: 1 mA maximum Y Fanout of 10 LS-TTL loads
