Product details

Overview

74HC107D-Q100 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 AEC-Q100 Grade 1 qualification for automotive use. Each flip-flop features independent J/K, clock (CP), and reset (R) inputs plus complementary Q and Q̅ outputs. It operates reliably from –40 °C to +125 °C in engine control units and body electronics.

For engineers reviewing the 74HC107D-Q100 datasheet, 74HC107D-Q100 pinout, 74HC107D-Q100 application, or 74HC107D-Q100 equivalent, key selection criteria include negative-edge triggering behavior, asynchronous reset timing (t_pd = 15–41 ns), input voltage compatibility (VIH/VIL thresholds per VCC), and SO14 package thermal derating (10.1 mW/K above 100 °C).

Technical Context

This device implements two independent edge-triggered JK bistables with fully asynchronous reset-each reset input (1R, 2R) forces Q = LOW and Q̅ = HIGH regardless of clock state. The J and K inputs must be stable for t_su = 3–26 ns before the HIGH-to-LOW clock transition to ensure correct toggle/set/reset/hold operation per the function table.

Input clamp diodes enable safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Output drive capability supports ±4.0 mA at VCC = 4.5 V (VOH ≥ 3.98 V, VOL ≤ 0.26 V), while static ICC remains below 80 μA over full temperature range, enabling low-power automotive subsystems.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	74HC high-speed CMOS - compatible with 3.3 V and 5 V systems; VIH = 3.15 V min at VCC = 4.5 V
Trigger Edge	Negative-edge (HIGH-to-LOW CP transition) - defines precise sampling point for J/K states
Reset Type	Asynchronous active-LOW - immediate Q/Q̅ override independent of clock, t_pd(R→Q) = 15–40 ns
Supply Range	2.0 V to 6.0 V - supports wide-input automotive battery rails including cold-crank (≈2.2 V) and load-dump transients
Temperature Range	–40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications
Propagation Delay	t_pd(CP→Q) = 15 ns typ at VCC = 6.0 V, CL = 50 pF - enables reliable 24 MHz operation in synchronous logic chains
Power Dissipation	P_tot = 500 mW max (SO14); derates 10.1 mW/K above 100 °C - constrains thermal design in sealed ECUs

Pinout & Package

74HC107D-Q100 uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, and gull-wing leads. Thermal resistance R_thJA = 100 K/W typical; maximum junction temperature = +150 °C.

Pin/Terminal	Circuit Role	Design Meaning
1, 8	J input (1J, 2J)	Synchronous data enable - HIGH sets next-state Q on clock edge if K = LOW
2, 6	Q̅ output (1Q̅, 2Q̅)	Complementary output - inverted logic level of corresponding Q pin; drives fanout loads up to 10 LSTTL
3, 5	Q output (1Q, 2Q)	True output - reflects stored state; VOH ≥ 3.98 V / VOL ≤ 0.26 V at 4.5 V, 4 mA
4, 11	K input (1K, 2K)	Synchronous data disable - LOW holds Q on clock edge if J = LOW; both HIGH toggles Q
9, 12	CP input (2CP, 1CP)	Negative-edge clock - HIGH-to-LOW transition samples J/K and updates outputs; t_W = 14 ns min pulse width
10, 13	R input (2R, 1R)	Asynchronous reset - active-LOW forces Q = LOW / Q̅ = HIGH immediately; t_rec = 6–15 ns before next CP
7	GND	Signal and power ground reference - must be low-impedance path to minimize switching noise coupling
14	VCC	Positive supply - decoupling capacitor (100 nF ceramic) required within 5 mm of pin for stable operation

Key Features

Feature	Design Value
AEC-Q100 Grade 1 qualification	Validated for automotive use from –40 °C to +125 °C ambient; includes latch-up immunity >100 mA per JESD78 Class II B
Input clamp diodes	Enable robust interface to signals exceeding VCC (e.g., 12 V sensors) when used with series current-limiting resistors
CMOS-level input thresholds	VIH = 3.15 V min / VIL = 1.35 V max at VCC = 4.5 V - ensures noise margin >1.0 V in 5 V systems
Low dynamic power	CPD = 30 pF per flip-flop - limits switching power to PD ≈ 1.2 mW at 10 MHz, VCC = 5 V, 2 inputs switching
ESD robustness	HBM >2000 V, CDM >1000 V - withstands handling and board assembly without special precautions

Applications

Engine Control Unit (ECU) Timing Sequencer

Automotive Body Control Module (BCM)

Use Scenario: Generating synchronized enable pulses for fuel injector drivers based on crankshaft position sensor edges.

IC Role / Device Role / Timing Role: Dual JK flip-flop acts as edge-sensitive synchronizer and state register - one section captures cam signal, second generates phase-shifted injection windows.

Use Value: Negative-edge triggering aligns precisely with falling edges of Hall-effect crank sensors; asynchronous reset clears latched faults during ECU restart.

Use Scenario: Debouncing and latching door lock/unlock commands from mechanical switches in central locking systems.

IC Role / Device Role / Timing Role: Each JK section implements a set-reset latch - J = unlock command, K = lock command, CP = filtered switch edge, R = system reset.

Use Value: Asynchronous reset ensures deterministic initial state after battery reconnect; wide VCC range tolerates 12 V nominal and 9 V cranking dips.

Instrument Cluster Display Controller

ADAS Camera Power Sequencing

Use Scenario: Managing display backlight enable/disable sequencing with soft-start timing in digital dashboards.

IC Role / Device Role / Timing Role: Flip-flops generate staggered enable signals for LED driver stages using clock-divided timing and manual reset override.

Use Value: Complementary Q/Q̅ outputs drive high-side and low-side FETs directly; 6.0 V max VCC supports 5 V logic rails with margin.

Use Scenario: Controlling power-up order of image sensor, ISP, and serializer ICs in rear-view camera modules.

IC Role / Device Role / Timing Role: One JK stage sequences 3.3 V rail enable, second manages 1.8 V rail with delay via RC-clock conditioning on CP input.

Use Value: Input clamp diodes protect against 5 V I²C bus transients; –40 °C to +125 °C rating matches camera housing thermal profile.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual JK flip-flop applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74HCT107D-Q100	TTL-compatible inputs (VIH = 2.0 V min at VCC = 4.5 V); identical pinout and timing	Better interoperability with legacy 5 V TTL logic; slightly higher ICC at VCC = 5.5 V	Select when interfacing to standard LS-TTL or older microcontrollers with 5 V outputs
SN74LV107AQPWRQ1	Lower VCC range (1.65–5.5 V); LV logic family; different pin mapping (SO-14 but non-identical pinout)	Not pin-compatible; requires PCB redesign; superior noise immunity at 3.3 V	Choose only for new 3.3 V designs requiring lower threshold voltages and enhanced ESD (4 kV HBM)

Compared with 74HC107D-Q100, the 74HCT107D-Q100 offers plug-in compatibility with TTL sources but trades off some noise margin, while SN74LV107AQPWRQ1 demands layout changes yet delivers better low-voltage stability and ESD resilience.

FAQ

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

The minimum HIGH or LOW pulse width (t_W) at CP input is 14 ns at VCC = 6.0 V, 16 ns at VCC = 4.5 V, and 20 ns at VCC = 2.0 V. This ensures sufficient time for internal metastability resolution and avoids invalid state transitions. Pulse widths below these values may cause setup/hold violations or indeterminate outputs.

Can the 74HC107D-Q100 drive LEDs directly?

No - its outputs are rated for ±4.0 mA at VCC = 4.5 V, insufficient for typical indicator LEDs (requiring 5–20 mA). Use external buffer transistors or dedicated LED drivers. However, it can directly drive CMOS or LSTTL inputs (fanout = 10) without degradation.

How does the asynchronous reset interact with the clock input?

The reset inputs (1R, 2R) operate independently of CP: asserting R = LOW forces Q = LOW and Q̅ = HIGH immediately, overriding any pending clock-triggered state change. Reset deassertion (R = HIGH) does not trigger an update - the next valid CP edge resumes normal JK operation.

Is there a recommended decoupling strategy for SO14 layout?

Place a 100 nF X7R ceramic capacitor between VCC (pin 14) and GND (pin 7), with trace length <5 mm and direct connection to ground plane. Add a 4.7 μF tantalum or aluminum polymer bulk capacitor near the power entry point. Avoid shared return paths with high-current circuits to prevent ground bounce.
