IDT74LVC32A
FEATURES:
DESCRIPTION:
The LVC32A quadruple 2-input positive -OR gate is built using advanced
dual metal CMOS technology. The LVC32A device performs the Boolean
function Y = A + B or Y =
A
·
B
in positive logic.
Inputs can be driven from either 3.3V or 5V devices. This feature allows
the use of this device as a translator in a mixed 3.3V/5V system environment.
The LVC32A has been designed with a ±24mA output driver. This driver
is capable of driving a moderate to heavy load while maintaining speed
performance.
DRIVE FEATURES:
• High Output Drivers: ±24mA
• Reduced system switching noise
APPLICATIONS:
• 5V and 3.3V mixed voltage systems
• Data communication and telecommunication systems
