The SN74LVTH574PW: The 3 pF input capacitance keeps the loading on the upstream driver low at 150 MHz. Quiescent current sits at 190 µA — negligible in an active system but worth noting if the register stays powered in a low-power sleep mode.
It carries ROHS3 compliance, so it meets the current EU restriction regime without an exemption expiry to track.
The SN74LVC574APWT is a close peer — same 8-bit D-type, positive-edge trigger, tri-state non-inverted outputs, and 150 MHz clock. The key difference is supply voltage: the LVC variant runs from 1.65 V to 3.6 V, while the LVTH requires 2.7 V minimum. Propagation delay on the LVC is 6.8 ns at 3.3 V, 50 pF, versus 4.5 ns for the LVTH. The LVC also comes in a tape-and-reel package variant. Pin-for-pin compatibility depends on the PCB footprint; both are 20-TSSOP.
