Texas Instruments SN74ABT16640

the abt16640 are inverting 16-bit transceivers designed for asynchronous communication between data buses. these devices 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 (1dir and 2dir) inputs. the output-enable (1 and 2) inputs can be used to disable the device so that the buses are effectively isolated. to ensure the high-impedance state during power up or power down should be tied to vcc through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. the sn54abt16640 is characterized for operation over the full military temperature range of -55c to 125c. view all in datasheet
