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) input can be used to disable the device so that the buses
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
CC
BIAS, which establishes a voltage between 1.3 V
and 1.7 V when V
CC
is not connected.
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.
