General Description
IDT74ALVCH162245 General Description
This 16-bit bus transceiver is built using advanced dual metal CMOS technology. The ALVCH162245 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 ALVCH162245 has series resistors in the device out-put structure of the "A" port which will significantly reduce line noise when used with light loads. This driver has been designed to drive ±12mA at the designated threshold levels.
The "B" port has a ±24mA driver. The ALVCH162245 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.
