Nexperia USA Inc. 74HC107D,653

Overview

74HC107D,653 from Nexperia is a dual negative-edge-triggered JK flip-flop with asynchronous active-LOW reset, CMOS-level inputs, 2.0–6.0 V supply range, and SO14 (SOT108-1) package. It implements synchronous state control in digital logic systems, supporting toggle, set, reset, and hold functions per flip-flop. Used in clock-domain synchronization, sequence control, and state-machine registers in industrial control and instrumentation.

For engineers reviewing the 74HC107D,653 datasheet, 74HC107D,653 pinout, 74HC107D,653 application, or 74HC107D,653 equivalent, key selection factors include negative-edge clocking behavior, independent J/K inputs per stage, asynchronous reset timing (t_rec = 13 ns @ V_CC = 6.0 V), propagation delay (t_pd = 15–41 ns), and guaranteed operation from –40 °C to +125 °C.

Technical Context

This device integrates two independent JK flip-flops sharing no internal coupling-each has dedicated J, K, CP, R, Q, and Q̅ terminals. The asynchronous reset operates independently of clock edges and forces Q = LOW regardless of J/K states. Clock triggering occurs only on HIGH-to-LOW transitions, requiring stable J/K inputs one setup time (t_su = 6–26 ns) prior to the falling edge.

Input clamp diodes allow safe interfacing to voltages exceeding V_CC when used with current-limiting resistors. Static input thresholds meet CMOS levels: VIH ≥ 3.15 V (V_CC = 4.5 V), VIL ≤ 1.35 V (V_CC = 4.5 V). Output drive capability is ±4 mA at V_CC = 4.5 V, with VOH ≥ 3.98 V and VOL ≤ 0.26 V under load.

FAQ

What is the minimum pulse width required on the clock input for reliable operation?

The minimum clock pulse width (t_W) is 14 ns at V_CC = 6.0 V, 16 ns at V_CC = 4.5 V, and 80 ns at V_CC = 2.0 V. This ensures sufficient time for internal metastability resolution and state capture; violating this spec risks invalid or metastable outputs.

Can the 74HC107D,653 be used with a 3.3 V supply?

Yes - the 74HC107D,653 is fully specified down to 2.0 V, including VIH ≥ 1.5 V and VIL ≤ 0.8 V at V_CC = 2.0 V. At 3.3 V, VIH = 2.31 V (min) and VIL = 1.09 V (max), providing adequate noise margin for 3.3 V CMOS systems.

Is the reset input truly asynchronous, and what is its timing impact?

Yes - the reset (R) input is asynchronous and active LOW. Its propagation delay to Q is 15–40 ns depending on V_CC, and it overrides all clock and J/K activity. Recovery time (t_rec) after reset release is 13–21 ns, defining the minimum interval before next clock edge.

Does this device support hot insertion or live swapping?

No - the 74HC107D,653 lacks hot-swap protection features such as power-on reset, I_OFF isolation, or back-drive immunity. Applying V_CC while inputs are driven can cause latch-up or excessive current; power sequencing per datasheet Section 7 is mandatory.
