(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
This 16-bit bus transceiver and register is designed for 1.65-V to 3.6-V VCC operation.
The SN74LVCH16652A consists of D-type flip-flops and control circuitry arranged for multiplexed transmission of
data directly from the data bus or from the internal storage registers. The device can be used as two 8-bit
transceivers or one 16-bit transceiver.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
