Functional Description

• Hex Inverter (Open Drain)

General

The 74HC05D is a high speed CMOS INVERTER fabricated with silicon gate C2MOS technology.

It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power

dissipation.

Pin configuration and function are the same as the 74HC04D, but the 74HC05D has high performance MOS Nchannel

transistor (open-drain) outputs.

This device can, therefore, with a suitable pull-up resistors, be used in wired-AND, LED drive and other

applications.

All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Features

(1) High speed: tpz = 8 ns (typ.) at VCC = 5 V

(2) Low power dissipation: ICC = 1.0 μA (max) at Ta = 25 

(3) Wide operating voltage range: VCC(opr) = 2.0 to 6.0 V

(4) Open drain structure
