This 16-bit bus transceiver is built using advanced dual metal CMOS technology. The ALVCH16245 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 directioncontrol (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.
The ALVCH16245 has been designed with a ±24mA output driver.
This driver is capable of driving a moderate to heavy load while maintaining speed performance.
The ALVCH16245 has "bus-hold" which retains the inputs' last state whenever the input bus goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors.
