The LVC16823A 18-bit register is built using advanced dual metal CMOS
technology. This high-speed, low-power register is ideal for use as a buffer
register for data synchronization and storage. The Output Enable (OE) and
clock (CLK) controls are organized to operate each device as two 9-bit
registers or one 18-bit register with common clock. Flow-through organization of signal pins simplifies layout. All inputs are designed with hysteresis
for improved noise margin.
All pins of the LVC16823A 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 LVC16823A has been designed with a ± 24mA output driver. The
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
