Nexperia USA Inc. 74HC107PW,118

Overview

74HC107PW,118 from Nexperia is a dual negative-edge-triggered JK flip-flop with asynchronous active-LOW reset, 14-pin TSSOP package, 2.0–6.0 V supply range, and guaranteed operation from –40 °C to +125 °C. It provides complementary Q/Q̅ outputs per section, individual J/K inputs, and supports synchronous toggle, set, reset, and hold functions in digital control, state machine, and clock division circuits.

For engineers reviewing the 74HC107PW,118 datasheet, 74HC107PW,118 pinout, 74HC107PW,118 application, or 74HC107PW,118 equivalent, this page delivers verified functional behavior, timing constraints (e.g., 19 ns t_pd at 4.5 V), pin-level circuit roles, real-world use cases in industrial logic sequencing, and validated alternatives for drop-in compatibility assessment.

Technical Context

This device implements two independent CMOS JK flip-flops sharing no internal coupling-each with dedicated J, K, CP, R, Q, and Q̅ terminals. The asynchronous reset operates independently of clock edges, enabling immediate state clearing regardless of CP phase.

Operation requires J/K inputs to be stable for ≥20 ns (at V_CC = 4.5 V) before the HIGH-to-LOW clock transition; propagation delay from CP to Q is 19 ns (typical), and maximum operating frequency reaches 66 MHz at 4.5 V with 15 pF load.

FAQ

What is the minimum setup time required for J and K inputs relative to the clock's HIGH-to-LOW transition?

At V_CC = 4.5 V, the guaranteed minimum setup time (t_su) is 20 ns. This ensures predictable state transitions; violating it risks metastability or incorrect toggling. The value scales inversely with supply voltage-e.g., 100 ns at 2.0 V-per Table 7 in the datasheet.

Can the asynchronous reset (R) be used while the clock is HIGH or floating?

Yes. Pin 10 and 13 (R inputs) operate independently of CP state. When pulled LOW, they force Q = 0 and Q̅ = 1 immediately-even if CP is HIGH, LOW, or unconnected-making them ideal for power-on initialization or fault recovery.

Does 74HC107PW,118 support mixed-voltage interfacing, such as driving 3.3 V inputs from a 5 V supply?

No. Its outputs swing rail-to-rail (0 V to V_CC), so with V_CC = 5 V, VOH ≈ 4.4 V-exceeding 3.3 V logic high thresholds. Use series resistors or level translators; the built-in clamp diodes only protect against overvoltage, not enable safe interfacing.

How does the TSSOP14 package (SOT402-1) compare thermally to the SO14 (SOT108-1) variant?

TSSOP14 has lower thermal resistance: P_tot derates at 7.3 mW/K above 81 °C, versus SO14's 10.1 mW/K above 100 °C. Thus, at 125 °C ambient, TSSOP14 sustains ~310 mW total dissipation vs. SO14's ~370 mW-but TSSOP offers 30 % smaller footprint and better high-frequency signal integrity.
