120 MHz octal D with wide supply margin
The 74AHC374D,112 is an octal D-type flip-flop from NXP's 74AHC series — eight positive-edge-triggered registers with tri-state, non-inverted outputs in a single 20-SOIC package. Clocked at 120 MHz, it captures data on the rising edge and holds it until the next clock or until the output-enable goes high to float the bus. Supply voltage spans 2 V to 5.5 V, so it runs on a 3.3 V or 5 V rail without a level translator on the supply side — common in mixed-voltage panels where the backplane is 5 V but the core logic is 3.3 V. Operating temperature covers -40°C to +125°C, which is the full industrial-automation range; it lives in an unheated cabinet or near a motor drive without derating.
Timing and drive at the bench level
Max propagation delay is 10.1 ns at 5 V with a 50 pF load — that is the time from clock edge to output valid. For a 120 MHz clock (8.33 ns period), the 10.1 ns delay means the output settles after the next clock edge unless the data path is pipelined; this part is better suited for bus-interface or register-file duty at lower clock rates or with registered inputs. Each output sources or sinks 8 mA — enough to drive a standard TTL load or a handful of CMOS inputs on a short trace, but not a long backplane or a 50-ohm terminated line without a buffer. Quiescent current sits at 4 µA typical, so the part's own draw is negligible in a battery-backed or always-on section of the board. Input capacitance is 3 pF per pin — light enough that the upstream driver sees a small load, which matters when the clock line fans out to multiple flip-flops.
20-SOIC wide — field-swap friendly
Housed in a 20-SOIC wide-body (7.50 mm body width, 0.295-inch pitch), the part is hand-solderable with a standard iron and a fine tip — no hot-air station required for a field repair. The wide pitch also means less risk of bridging during a quick swap on site. The supplier device package is 20-SO, which is the same footprint as the standard SOIC-20 wide — confirm the board land pattern matches the 7.50 mm body width, not the narrow 3.90 mm version.
Active production, sourced to order
ROHS3 compliant per the manufacturer — no restricted substances above the threshold; the part ships in a tube, not tape-and-reel, so it arrives loose for manual placement or small-batch assembly.
