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.

description/ordering information
The SN74LVTH162245 is a 16-bit (dual-octal) noninverting 3-state transceiver designed for low-voltage (3.3-V)
V_CC operation, but with the capability to provide a TTL interface to a 5-V system environment.
This device can be used as two 8-bit transceivers or one 16-bit transceiver. 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 effectively are
isolated.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
