MM54HC34/MM74HC34 Non-Inverter General Description The MM54HC34/MM74HC34 are logic functions fabricated by using advanced silicon-gate CMOS technology which provides the inherent benefits of CMOSÐlow quiescent power and wide power supply range, but are functionally as well as pin-out compatible with standard DM54LS/74LS devices. The MM54HC34/MM74HC34 feature low power dissipation and fast switching times. All inputs are protected from static discharge by internal diodes to VCC and ground. Features Y Fast switching: tPLH, tPHL e 10 ns (typ) Y High fanout: t 10 LS loads
