The MC74HC05A contains six inverters with open drain outputs. The MC74HC05A is identical to the MC74HC04A, except for the open drain outputs. The outputs can be connected to other open drain outputs to implement active LOW wired OR or active High wired AND logic functions. The open drain outputs require pull up resistors to perform correctly.
Output Drive Capability: 10 LSTTL Loads with Suitable Pullup Resistor
Outputs Directly Interface to CMOS, NMOS and TTL
High Noise Immunity Characteristic of CMOS Devices
Operating Voltage Range: 2.0 to 6.0 V
Low Input Current: 1 µA
In Compliance With the JEDEC Standard No. 7A Requirements
