Product details

The SN74LV175AD is a single-element 4-bit D-type flip-flop from the 74LV series. It captures data on the positive edge of the clock and presents complementary outputs. A master-reset input forces all outputs low asynchronously.

The 165 MHz clock frequency is the maximum toggle rate. Propagation delay is 9.3 ns at 5V with a 50 pF load. The 12 mA output drive charges a short trace or one to two standard CMOS loads.

There is no last-time-buy or end-of-life notice on this part. For BOM resilience, the 16-SOIC footprint is shared across the 74LV and 74LVC families, so a pin-compatible second source from another logic family is straightforward if supply tightens.

Frequently asked questions

Is SN74LV175AD compatible with 3.3V logic?

Yes. The 2V to 5.5V supply range covers 3.3V operation directly. At 3.3V the input thresholds scale with VCC, so a 3.3V microcontroller or FPGA output drives the flip-flop reliably without a level shifter.

What is the difference between SN74LV175AD and SN74LV175AN?

The suffix 'D' indicates a 16-SOIC surface-mount package, while 'N' typically indicates a 16-pin DIP through-hole package. The electrical specifications (clock frequency, supply range, temperature grade) are identical; the choice is a board-assembly and footprint decision.
