T
A
= -55
to 125 C for all packages
The IN74HCU04A is identical in pinout to the 74LS04. This contain
six independent unbuffered inverters. These inverters are well suited for
use as oscillators, pulse shapers and in many other applications requiring
a high-input impedance amplifier.
This device is characterized for over wide temperature ranges to meet
industry and ation over military specifications.
Low Power consumption characteristic of CMOS devices
Output drive capability: 10 LS TTL Loads Min.
Operating speed superior to LS TTL
Wide operating voltage range: 2.0 to 6.0 V
Low input current: 1.0
A Max.
Low quiescent current: 20
A Max.
High noise immunity characteristic of CMOS
Diode protection on all inputs

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, V
IN
and V
OUT
should be constrained to the range GND
(V

or

)

.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
CC
). Unused
outputs must be left open.
