DESCRIPTION:
technology. The ALVCH16245 is designed for asynchronous communication
between data buses. The control-function implementation minimizes external
timing requirements.
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.
driver is capable of driving a moderate to heavy load while maintaining speed
performance.
whenever the input bus goes to a high impedance. This prevents floating inputs
and eliminates the need for pull-up/down resistors.
2
This 16-bit bus transceiver is built using advanced dual metal CMOS
This device can be used as two 8-bit transceivers or one 16-bit transceiver.
The ALVCH16245 has been designed with a ±24mA output driver. This
The ALVCH16245 has “bus-hold” which retains the inputs’ last state
