Quad 2-Input OR Gate
Note:
The TC74VHCT32A is an advanced high speed CMOS
2-INPUT OR GATE fabricated with silicon gate C
2
MOS
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 output.
The input voltage are compatible with TTL output voltage.
This device may be used as a level converter for interfacing 3.3
V to 5 V system.
Input protection and output circuit ensure that 0 to 5.5 V can
be applied to the input and output
(Note)
pins without regard to
the supply voltage. These structure prevents device destruction
due to mismatched supply and input/output voltages such as
battery back up, hot board insertion, etc.
