Component qualification in accordance with JEDEC and

industry standards to ensure reliable operation over an

extended temperature range. This includes, but is not limited

to, Highly Accelerated Stress Test (HAST) or biased 85/85,

temperature cycle, autoclave or unbiased HAST,

electromigration, bond intermetallic life, and mold compound

life. Such qualification testing should not be viewed as

justifying use of this component beyond specified

performance and environmental limits.

The SN74ABT16245A-EP is a 16-bit noninverting 3-state transceiver designed for synchronous two-way

communication

between

data

buses.

The

control-function

implementation

minimizes

external

timing

requirements.

This device 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 (DIR)

input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.

the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN74ABT16245A-EP is characterized for operation from –55

°C to 125°C.
