Product details
Overview
74ABT74D,118 from Nexperia is a dual positive-edge-triggered D-type flip-flop with independent asynchronous set (active LOW) and reset (active LOW) inputs per channel, complementary Q/Q̅ outputs, 180 MHz maximum clock frequency at 5.0 V, 3.0 ns typical propagation delay (CP to Q), and IOFF-enabled partial power-down protection. It operates across -40 °C to +85 °C and is used in synchronous logic control, bus interface latching, and clock-domain synchronization in industrial control modules.
For engineers reviewing the 74ABT74D,118 datasheet, 74ABT74D,118 pinout, 74ABT74D,118 application, or 74ABT74D,118 equivalent, key selection criteria include guaranteed 150 MHz operation over full temperature range, TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), IOFF leakage < ±100 μA at VCC = 0 V, and SO14 (SOT108-1) package compatibility with legacy PCB footprints.
Technical Context
This device implements two independent edge-triggered D flip-flops sharing no internal coupling-each with dedicated SD, RD, D, CP, Q, and Q̅ terminals. Its BiCMOS architecture delivers TTL-level input compatibility and 20 mA sink / 15 mA source output drive while maintaining low static current (ICC ≤ 50 μA).
The IOFF circuit disables outputs during power-down by disconnecting I/O pins from internal circuitry when VCC = 0 V, preventing backflow current. Asynchronous set/reset override clock action and are functional down to 0 V on control pins, enabling system-level reset coordination without clock dependency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 4.5 V to 5.5 V - Ensures robust operation under industrial rail tolerances and compatibility with 5 V TTL/CMOS systems. |
| Max clock frequency | 150 MHz (–40 °C to +85 °C) - Supports high-speed data capture in real-time control loops and digital signal routing. |
| Propagation delay (CP→Q) | 1.0–4.7 ns - Enables sub-5 ns timing margins for tight setup/hold windows in synchronous designs. |
| IOFF leakage current | ±100 μA at VCC = 0 V - Guarantees safe hot-insertion and multi-voltage domain isolation without external isolation circuitry. |
| Output drive (IOL/IOH) | 20 mA sink / –15 mA source - Drives standard TTL loads directly without buffer stages. |
| Input voltage thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - Matches legacy TTL logic families for seamless integration into mixed-technology boards. |
| Operating temperature | –40 °C to +85 °C - Qualified for extended industrial environments including factory automation and outdoor telecom equipment. |
Pinout & Package
74ABT74D,118 is packaged in SO14 (SOT108-1): plastic small outline, 14-lead, 3.9 mm body width, 1.27 mm lead pitch. Pin 1 index marked via notch or bevel; pin 1 is top-left when notch faces up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 (1RD, 2RD) | Asynchronous reset (active LOW) | Forces Q = LOW regardless of clock or data state; enables global or per-channel hard reset. |
| 2, 12 (1D, 2D) | Data input | Samples and stores logic level on rising CP edge; requires 2.4 ns setup and 0 ns hold time at 5 V. |
| 3, 11 (1CP, 2CP) | Clock input (LOW-to-HIGH edge) | Triggers storage of D-input value; edge sensitivity eliminates metastability from slow transitions. |
| 4, 10 (1SD, 2SD) | Asynchronous set (active LOW) | Forces Q = HIGH independently of clock; supports priority initialization or fault-safe states. |
| 5, 9 (1Q, 2Q) | True output | Reflects stored D value after CP edge; drives downstream logic or bus lines with 20 mA sink capability. |
| 6, 8 (1Q̅, 2Q̅) | Complement output | Provides inverted logic state; eliminates need for external inverters in differential signaling or enable logic. |
| 7 | GND | Reference ground for all I/O and internal circuitry; must be low-impedance connection to minimize noise coupling. |
| 14 | VCC | Primary supply rail; decoupling capacitor (100 nF) required within 5 mm for stable high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| BiCMOS process technology | Combines bipolar speed and CMOS low static power-delivers 250 MHz typ fMAX at 25 °C with ICC ≤ 5 μA standby. |
| IOFF partial power-down | Automatically isolates I/O pins when VCC = 0 V, eliminating backfeed paths in hot-swap or multi-rail systems. |
| TTL-compatible input thresholds | VIH = 2.0 V min and VIL = 0.8 V max ensure direct interfacing with 5 V TTL without level-shifting components. |
| Latch-up immunity | Exceeds 500 mA per JESD78B Class II Level A-prevents destructive latch-up under transient overvoltage conditions. |
| ESD robustness | HBM > 2000 V and CDM > 1000 V-reduces handling sensitivity and improves board-level reliability in manufacturing. |
Applications
| Industrial PLC I/O Expansion | Digital Bus Interface Latching |

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 |
|---|---|---|---|
| SN74ABT74N | Same logic function and pinout, but PDIP-14 package (not surface-mount); higher parasitic inductance limits fMAX to 125 MHz. | Preferred for through-hole prototyping or legacy repair; unsuitable for high-density SMT layouts. | Select only if manual assembly or socket-based testing is required; otherwise avoid due to thermal and density limitations. |
| 74LVC74AD,118 | Lower VCC range (1.65–3.6 V), 3.3 V native operation; 10 ns propagation delay at 3.3 V; no IOFF circuitry. | Designed for battery-powered or low-power embedded systems-not compatible with 5 V TTL interfaces. | Choose only for 3.3 V domains requiring lower power; not a drop-in replacement due to voltage and IOFF incompatibility. |
Compared with SN74ABT74N and 74LVC74AD,118, the 74ABT74D,118 uniquely balances 5 V TTL interoperability, 150 MHz industrial-grade speed, and IOFF-enabled power sequencing-making it the sole option for robust 5 V SMT logic in mixed-rail or hot-swap systems.

FAQ
Does 74ABT74D,118 support hot-swap operation?
Yes. Its IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±100 μA and preventing damage during live insertion into powered backplanes. This behavior is guaranteed across –40 °C to +85 °C and does not require external control signals.
What is the minimum pulse width required for asynchronous set/reset inputs?
The minimum LOW pulse width for 1SD/2SD and 1RD/2RD is 2.2 ns over full temperature range, verified per Table 7 (tW parameter). This allows use with fast microcontroller GPIOs or FPGA-generated reset pulses without external stretching circuits.
Can 74ABT74D,118 drive standard TTL loads directly?
Yes. It sources –15 mA (IOH) and sinks 20 mA (IOL) at VCC = 4.5 V, exceeding standard TTL fan-out requirements (IOL ≥ 16 mA). No series resistors or buffer stages are needed when driving 74LS or 74F-series inputs.
Is there a version of this device qualified for automotive applications?
No. The 74ABT74D,118 is specified for industrial temperature range (–40 °C to +85 °C) and is not AEC-Q100 qualified. Nexperia offers separate automotive-grade variants (e.g., 74ABT74AD-Q100) with extended qualification testing and different packaging.
