MM74HCT05 is a six-transistor open drain inverter manufactured by Fairchild Semiconductor Corporation. It has LS-TTL pinout and threshold compatibility, a maximum load current of 10 LS-TTL loads, and typical propagation delays of tPZL (1kΩ resistor) 10ns and tPLZ (1kΩ resistor) 8ns.
The MM74HCT05 is a logic function fabricated using advanced silicon-gate CMOS technology, offering low quiescent power and a wide power supply range. It is input and output characteristic and pinout compatible with standard DM74LS logic families. The device features an open drain output that requires an external resistor to perform a wire-NOR function, and all inputs are protected from static discharge damage by internal diodes.
