What this 74195PC shift register does
The 74195PC is a TTL H/L series parallel-in/parallel-out shift register.
Sourcing and lifecycle reality
It is RoHS non-compliant, which means it uses lead-bearing solder terminations — a consideration for any new design targeting RoHS exemption or a legacy repair depot that needs the original alloy.
Packaging and handling note
That suits bench-level assembly, prototype runs, or small-batch rework where a pick-and-place feeder is not involved.
