Product details
Overview
74LVC74ADB,118 from Nexperia is a dual positive-edge-triggered D-type flip-flop with asynchronous active-LOW set (nSD) and reset (nRD), 14-pin SSOP package, 1.2 V to 3.6 V supply range, and guaranteed operation from –40 °C to +125 °C - used for synchronous data latching and state storage in low-voltage digital control logic.
For engineers reviewing the 74LVC74ADB,118 datasheet, 74LVC74ADB,118 pinout, 74LVC74ADB,118 application, or 74LVC74ADB,118 equivalent, this device supports precise edge-triggered state capture in mixed-voltage systems, offers Schmitt-trigger inputs for noise immunity, and delivers sub-7 ns propagation delay at 3.3 V - critical for timing-critical clock domain interfacing and register file design.
Technical Context
This dual D-flip-flop implements two independent edge-triggered storage cells, each with separate D, CP, SD, RD, Q, and Q̅ terminals. Its asynchronous set/reset inputs operate independently of the clock and override all synchronous behavior when asserted LOW.
The device uses CMOS technology with Schmitt-trigger inputs, enabling robust operation with slow-rising or noisy signals. It complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 across its full 1.2–3.6 V supply range and supports 5 V-tolerant inputs for legacy interface compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - enables direct integration into battery-powered and multi-rail embedded systems without level-shifting. |
| Propagation Delay (tpd) | ≤ 5.2 ns at VCC = 3.3 V - ensures reliable setup/hold timing margins in ≥120 MHz synchronous logic paths. |
| Maximum Clock Frequency | 150 MHz at VCC = 3.0–3.6 V - supports high-speed data sampling and pipeline stage synchronization. |
| Input Voltage Tolerance | 0 V to 5.5 V - allows safe interfacing with 5 V TTL outputs while powered from 1.8 V or 2.5 V rails. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive control modules and industrial motor drives. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - reduces risk of field failure during PCB handling and system integration. |
| Power Dissipation Capacitance | CPD = 19.1 pF at 3.3 V - enables accurate dynamic power estimation for thermal-aware board layout. |
Pinout & Package
74LVC74ADB,118 is supplied in a 14-lead SSOP package (SOT337-1), body width 5.3 mm, pitch 0.65 mm, with exposed pad not electrically connected. Pin 1 is marked by a notch or dot; pin numbering follows standard counter-clockwise convention from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1RD, 13RD | Asynchronous Reset (active LOW) | Forces 1Q LOW regardless of clock or data - used for hardware-initiated state clearing in safety-critical sequences. |
| 2, 12 | Data Input (1D, 2D) | Samples input value on rising clock edge - requires stable data ≥2.0 ns before CP transition at 3.3 V. |
| 3, 11 | Clock Input (1CP, 2CP) | Positive-edge-triggered - transitions from LOW to HIGH latch data into respective flip-flop output registers. |
| 4, 10 | Asynchronous Set (1SD, 2SD) | Forces 1Q HIGH regardless of clock or data - enables immediate assertion of control flags or error states. |
| 5, 9 | True Output (1Q, 2Q) | Complementary to Q̅ - drives downstream logic loads up to 24 mA sink/source at 3.3 V. |
| 6, 8 | Complement Output (1Q̅, 2Q̅) | Inverted copy of true output - eliminates need for external inverters in toggle or differential signaling paths. |
| 7 | GND | Reference ground plane connection - must be low-impedance to maintain noise margin and switching integrity. |
| 14 | VCC | Primary supply rail - decoupling capacitor (100 nF ceramic) required within 5 mm of this pin for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable operation with slow or noisy clock/data edges - eliminates metastability risk from marginal slew rates. |
| 5 V tolerant inputs | Permits direct connection to legacy 5 V microcontrollers or logic families without external translators or resistors. |
| Wide temperature range | –40 °C to +125 °C operation confirmed per JEDEC JESD22-A108 - suitable for engine control units and power converters. |
| Low dynamic power | Typical ICC = 0.1 μA at VCC = 3.6 V - reduces quiescent current in always-on subsystems like watchdog timers. |
| Multiple package options | SSOP (SOT337-1), SO14 (SOT108-1), TSSOP14 (SOT402-1), DHVQFN14 (SOT762-1), DHXQFN14 (SOT8014-1) - supports footprint flexibility across density tiers. |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |
|---|---|
Use Scenario: Latching sensor status (door open/closed, seatbelt fastened) across multiple CAN nodes with synchronized polling intervals. IC Role / Device Role / Timing Role: Dual D-flip-flop stores sampled GPIO states on master clock edge; asynchronous set/reset enables fail-safe reset via watchdog timeout. Use Value: Eliminates software polling overhead and guarantees deterministic state capture at 100 kHz update rate with <7 ns jitter. |
Use Scenario: Synchronizing headlight dimming commands between LIN master and LED driver ICs under variable battery voltage (9–16 V). IC Role / Device Role / Timing Role: Buffers and retimes PWM enable signals from microcontroller to gate drivers; Schmitt inputs reject alternator ripple noise. Use Value: Prevents unintended LED flicker during cranking transients by rejecting sub-100 ns glitches on control lines. |
| Medical Infusion Pump Controller | IoT Edge Node Data Buffering |
Use Scenario: Capturing flow sensor pulses and motor step commands in real-time safety-critical path with redundant validation logic. IC Role / Device Role / Timing Role: First-stage synchronizer for asynchronous sensor interrupts; Q/Q̅ outputs feed cross-check comparators for fault detection. Use Value: Provides sub-5 ns inter-output skew to ensure simultaneous evaluation of mirrored signals in SIL-2 compliant architecture. |
Use Scenario: Holding sensor readings (temperature, humidity) until BLE radio enters transmit-ready state in ultra-low-power sleep/wake cycles. IC Role / Device Role / Timing Role: Low-leakage data latch retains measurement values during 3.3 V rail shutdown; 0.1 μA ICC minimizes standby drain. Use Value: Extends coin-cell battery life beyond 2 years by eliminating need for MCU wake-up solely to preserve data. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC74APWRE4 | Same logic function, TSSOP14 (SOT402-1) package; identical electrical specs but 0.65 mm pitch vs. SSOP's 0.65 mm - pin-compatible but different thermal resistance (RθJA = 137 K/W vs. 150 K/W). | Preferred for reflow-soldered high-density boards where thermal dissipation >50 mW is expected. | Select when board assembly uses automated optical inspection (AOI) optimized for TSSOP land patterns. |
| 74AUP2G74DC,125 | Ultra-low-power variant (AUP family); max fmax = 40 MHz at 3.3 V; tpd = 11.5 ns; VCC range 0.8–3.6 V; only 8-pin package (dual but no individual SD/RD per FF). | Suitable for energy-constrained wearables but lacks independent asynchronous controls per flip-flop - limits use in fault-recovery circuits. | Choose only if power budget <10 μW per flip-flop dominates over timing and control flexibility requirements. |
Compared with SN74LVC74APWRE4, 74LVC74ADB,118 offers superior thermal performance in SSOP for intermittent high-load operation; versus 74AUP2G74DC,125, it provides full asynchronous control and 3.7× higher speed - making it the sole choice for real-time control loops requiring deterministic reset behavior.

FAQ
Is 74LVC74ADB,118 pin-compatible with older 74HC74 variants?
No - 74LVC74ADB,118 uses SSOP-14 (SOT337-1) with 0.65 mm pitch, while standard 74HC74 typically uses SO14 (SOT108-1) with 1.27 mm pitch. Pin functions match (1RD, 1D, 1CP, 1SD, 1Q, 1Q̅, GND, VCC, 2Q̅, 2SD, 2CP, 2D, 2RD), but mechanical layout and thermal characteristics differ significantly.
Can the asynchronous set and reset inputs be left unconnected?
No - floating nSD or nRD pins may drift to intermediate voltages due to leakage, causing unintended flip-flop resets or sets. Each must be actively pulled HIGH via ≥10 kΩ resistor to VCC unless intentionally driven by system logic.
What is the minimum pulse width required on the clock input?
At VCC = 3.0–3.6 V, the minimum clock HIGH and LOW pulse width is 3.3 ns per Table 8. This ensures reliable edge detection and avoids metastability - verified across –40 °C to +125 °C with 30 pF load and ≤2.5 ns rise/fall times.
Does 74LVC74ADB,118 support partial power-down modes?
No - the device has no dedicated power-down or I3C-compatible sleep mode. However, ICC remains ≤0.1 μA at VCC = 3.6 V with all inputs static, enabling effective "quiescent hold" when clocks and data are halted - verified per Table 7 static characteristics.
