54ACT16861 Datasheet | Texas Instruments

description The ’ACT16861 are noninverting 20-bit transceivers designed for asynchronous munication between data buses. The control-function implementation minimizes external timing requirements. The ’ACT16861 can be used as two 10-bit transceivers or one 20-bit transceiver. They allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the output-enable (OEAB or OEBA) inputs. The output-enable inputs can be used to disable the device so that the buses are effectively isolated. 54ACT16861, 74ACT16861 20-BIT BUS TRANSCEIVERS WITH 3-STATE OUTPUTS SCAS197B - JUNE 1990 - REVISED NOVEMBER 1996 54ACT16861 . . .
