descriptionThe ’ABTH16245 devices are 16-bit noninverting
3-state transceivers that provide synchronous
two-way communication between data buses.
The control-function implementation minimizes
external timing requirements.
These devices can be used as two 8-bit transceivers or one 16-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) input. The output-enable (OE) input can be used to disable the devices so that the buses are effectively
isolated.
When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 2.1 V, OE 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.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN54ABTH16245 is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74ABTH16245 is characterized for operation from –40°C to 85°C.
