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 SN74LVTH16374 is a 16-bit edge-triggered D-type flip-flop with 3-state outputs designed for low-voltage
(3.3-V) V operation, but with the capability to provide a TTL interface to a 5-V system environment. This
CC
device is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working
registers.
This device can be used as two 8-bit flip-flops or one 16-bit flip-flop. On the positive transition of the clock (CLK),
the Q outputs of the flip-flop take on the logic levels set up at the data (D) inputs.
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.
