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 鹵24mA output driver. This driver
is capable of driving a moderate to heavy load while maintaining speed
performance.
DRIVE FEATURES:
鈥?High Output Drivers: 鹵24mA
鈥?Suitable for heavy loads
APPLICATIONS:
鈥?3.3V high speed systems
鈥?3.3V and lower voltage computing systems
