• 3.3V and lower voltage computing systems

DRIVE FEATURES:

• High Output Drivers: ±24mA

• Suitable for heavy loads

DESCRIPTION:

This 16-bit bus transceiver is built using advanced dual metal CMOS

technology. The ALVC16245 is designed for asynchronous communication

between data buses. The control-function implementation minimizes external

timing requirements.

This device can be used as two 8-bit transceivers or one 16-bit transceiver.

It allows data transmission from the A bus to the B bus or from the B bus to the

A bus, depending on the logic level at the direction-control (DIR) input. The

output-enable (OE) input can be used to disable the device so that the buses

are effectively isolated.

The ALVC16245 has been designed with a ±24mA output driver. This driver

is capable of driving a moderate to heavy load while maintaining speed

performance.
