(1) 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.
DESCRIPTION/ORDERING INFORMATION
The SN74LVTH16543 is a 16-bit registered transceiver designed for low-voltage (3.3-V) VCC 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. Separate latch-enable (LEAB or LEBA) and output-enable (OEAB or
OEBA) inputs are provided for each register to permit independent control in either direction of data flow.
