8-bit D-type, 120 MHz, 20-TSSOP
The SN74AHC374PW is an 8-bit D-type flip-flop from TI's 74AHC family, with a positive-edge trigger and tri-state non-inverted outputs. It clocks at 120 MHz and operates from 2 V to 5.5 V, making it a fit for 3.3 V and 5 V logic buses. Housed in a 20-TSSOP (4.40 mm wide) with surface-mount mounting, this part is aimed at general-purpose data storage and bus-interface applications where a single 8-bit register with output-enable control is needed.
Timing, drive, and supply range
Maximum propagation delay is 10.1 ns at 5 V with a 50 pF load — this sets the timing budget for the downstream logic. The 8 mA symmetric output drive (both high and low) is enough to drive a few TTL or CMOS inputs on a short trace, but a buffer is needed for longer backplane runs. Quiescent current is 4 µA, and input capacitance is 4 pF per input — both low enough that the part does not load the clock or data bus significantly in a multi-drop configuration. The 2 V to 5.5 V supply range covers 3.3 V and 5 V rails without a separate level translator, though the input thresholds scale with VCC per the AHC family spec.
Active, RoHS3, -40 to +85 °C
Texas Instruments lists the SN74AHC374PW as Active in production, with RoHS3 compliance. The operating temperature range is -40 °C to +85 °C — standard industrial grade, suitable for most indoor and telecom equipment.
