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 SN74LVC574A-EP octal edge-triggered D-type flip-flop is designed for 2.7-V to 3.6-V VCC operation.
This device features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance
loads. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working
registers.
On the positive transition of the clock (CLK) input, the Q outputs are set to the logic levels at the data (D) inputs.
A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high or
low logic levels) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the
bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines
without interface or pullup components.
OE does not affect the internal operations of the flip-flops. Old data can be retained or new data can be entered
while the outputs are in the high-impedance state.
