74VHCU04 Hex Inverter
December 1996
74VHCU04
Hex Inverter
General Description
The 74VHCU04 is an advanced high speed CMOS INVERT-
ER fabricated with silicon gate CMOS technology. It
achieves the high speed operation similar to equivalent Bi-
polar Schottky TTL while maintaining the CMOS low power
dissipation.
Since the internal circuit is composed of a single stage in-
verter, it can be used in analog applications such as crystal
oscillators. An input protection circuit ensures that 0V7V
can be applied to the input pins without regard to the supply
voltage. This device can be used to interface 5V to 3V sys-
tems and two supply systems such as battery back up. This
circuit prevents device destruction due to mismatched sup-
ply and input voltages.

Note 1:
Absolute Maximum Ratings are values beyond
which the device may be damaged or have its useful life
impaired. The databook specifications should be met, with-
out exception, to ensure that the system design is reliable
over its power supply, temperature, and output/input load-
ing variables. National does not recommend operation out-
side databook specifications.

Capacitance
Note 1: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average
operating current can be obtained by the equation: ICC (opr.) eCPD *VCC *fIN aICC/6 (per gate).
