TECHNICAL DATA
IN74HCU04
Hex Unbuffered Inverter
High-Performance Silicon-Gate CMOS
The IN74HCU04A is identical in pinout to the LS/ALS04. The
device inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LS/ALSTTL outputs.
This device consists of six single-stage inverters. These inverters
are well suited for use as oscillators, pulse shapers, and in many other
applications requiring a high-input impedance amplifier. For digital
applications, the HC04 is recommended.

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
IN
or V
OUT
)≤V
CC
.
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.
