74VHC32
Quad 2-Input OR Gate
General Descript ion
The VHC 3 2 is an advanced h igh speed CM OS 2 -In put OR
Gate fabricated with silicon gate CMOS technology. It
achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low
power dissipation.
The internal circuit is composed of 4 stages including buffer
output, which provide high noise immunity and stable out-
put. An input protection circuit ensures that 0V to 7V can be
applied to the input pins without regar d to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supp ly systems such as battery back up. This cir-
cuit preven ts device destruc tion du e to mismatch ed supply
and input voltages.

Absolute Maximum Ratings(Note 2) Recommended Operating
Conditions (Note 3)
Note 2: Absolute Maximum Ratings are values beyond which the device
may be damaged or have its useful life impaired. The databook specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside databook specifica-
tions.
Note 3: Unu s ed inputs m us t be held HIG H or LOW. They may no t float.
