具有三态输出的36位总线收发器 36-BIT BUS TRANSCEIVERS WITH 3-STATE OUTPUTS
description
The ’ABTH32245 are 36-bit quad 9-bit noninverting 3-state transceivers designed for synchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements.
These devices can be used as four 9-bit transceivers, two18-bit transceivers, or one 36-bit transceiver. They allow 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 inputs. The output-enable OE inputs can be used to disable the device so that the buses are effectively isolated.
