The MM74HCT05 is a logic funcTIon fabricated by usingadvanced silicon-gate CMOS technology, which providesthe inherent benefits of CMOS—low quiescent power andwide power supply range. The device is also input and outputcharacterisTIc and pinout compaTIble with standardDM74LS logic families. The MM74HCT05 open drain HexInverter requires the addiTIon of an external resistor to performa wire-NOR function.All inputs are protected from static discharge damage byinternal diodes to VCC and ground.MM74HCT devices are intended to interface between TTLand NMOS components and standard CMOS devices.These parts are also plug-in replacements for LS-TTLdevices and can be used to reduce power consumption inexisting designs.Featuresn Open drain for wire-NOR functionn LS-TTL pinout and threshold compatiblen Fanout of 10 LS-TTL loadsn Typical propagation delays:tPLH (with 1 kW resistor) 10 nstPHL (with 1 kW resistor) 8 ns
