The SN74ABTE16246 is an 11-bit noninverting
23
26
transceiver designed for asynchronous two-way
24
25
communication between buses. This device has
open-collector and 3-state outputs. The device
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 (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-Ω 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 VCCBIAS, which establishes a voltage between 1.3 V
and 1.7 V when VCC is not connected.
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors
with the bus-hold circuitry is not recommended.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

C. Temperature skew, tsk(temp), is the output skew of two devices, both having the same value of VCC ± 1% and with package
