INFORMATION
DESCRIPTION:
The LVC14A Hex Schmitt-trigger inverter is built using advanced dual
metal CMOS technology. This device contains six independent inverters
and performs the Boolean function Y =
A.
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 supply system.
The LVC14A 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 for LVC14A:
– High Output Drivers:
±24mA
– Reduced system switching noise
APPLICATIONS:
• 5V and 3.3V mixed voltage systems
• Data communication and telecommunication systems
