DRIVE FEATURES:
• High Output Drivers: ±24mA
• Reduced system switching noise
DESCRIPTION:
The LVC125A quadruple bus buffer gate is built using advanced dual
metal CMOS technology. The LVC125A features independent line drivers
with 3-state outputs. Each output is disabled when the associated output-
enable (OE) input is high.
To ensure the high impedance state during power up or power down,
OE should be tied to Vcc through a pullup resistor; the minimum value of the
resistor is determined by the current-sinking capability of the driver.
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 LVC125A has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
APPLICATIONS:
• 5V and 3.3V mixed voltage systems
• Data communication and telecommunication systems
