(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.
The SN74LVTH16244A is a 16-bit buffer and line driver 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 four 4-bit
buffers, two 8-bit buffers, or one 16-bit buffer. This device provides true outputs and symmetrical active-low
output-enable ( OE) inputs.
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown
resistors with the bus-hold circuitry is not recommended.
