description
The ’ABTE16246 devices are 11-bit noninverting transceivers designed for asynchronous two-way communication between buses. These devices have open-collector and 3-state outputs. 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 are effectively isolated. When OE
is low, the device is active.
The B port has an equivalent 25- series output resistor to reduce ringing. Active bus-hold inputs on the B port hold unused or floating inputs at a valid logic level.
The A port provides for the precharging of the outputs via V and 1.7 V when V
is not connected.
CC
The SN54ABTE16246 is characterized for operation over the full military temperature range of –55°C to 125°C. The SN74ABTE16246 is characterized for operation from –40°C to 85°C.
