Supply original MM74HCT05SJX, Logic - Gates and Inverters, by ON Semiconductor

General Description
The MM74HCT05 is a logic function fabricated by using advanced silicon-gate CMOS technology, which provides the inherent benefits of CMOS—low quiescent power and wide power supply range.
The device is also input and output characteristic and pinout compatible with standard DM74LS logic families.
The MM74HCT05 open drain Hex Inverter requires the addition of an external resistor to perform a wire-NOR function. All inputs are protected from static discharge damage by internal diodes to VCC and ground. MM74HCT devices are intended to interface between TTL and NMOS components and standard CMOS devices.
These parts are also plug-in replacements for LS-TTL devices and can be used to reduce power consumption in existing designs.
Features
• Open drain for wire-NOR function
• LS-TTL pinout and threshold compatible
• Fanout of 10 LS-TTL loads
• Typical propagation delays: tPLH (with 1 kΩ resistor) 10 ns tPHL (with 1 kΩ resistor) 8 ns
