What this 54175FMQB TTL D flip-flop is and where it lands
The 54175FMQB is a D flip-flop from the TTL/H/L series, built in standard TTL logic. It stores one data bit per flip-flop on the rising edge of the clock input, with complementary Q and Q-bar outputs.
Active production status — no end-of-life concern
The RoHS compliance status is listed as non-compliant, which is typical for older TTL logic families that use lead-bearing solder finishes; factor this into BOM reviews for markets with RoHS exemptions or legacy equipment allowances.
For pick-and-place assembly you will need to transfer to a feeder-compatible carrier; for hand-assembly or rework, Bulk is straightforward.
