Product details
Overview
N74F74N,602 from Nexperia is a dual positive-edge-triggered D-type flip-flop in a 14-pin plastic DIP package, operating at 5V supply with 125MHz maximum clock frequency, 11.5mA typical total supply current, and –40°C to +85°C industrial temperature range; used for synchronous data latching and edge-triggered state storage in digital control logic.
For engineers reviewing the N74F74N,602 datasheet, N74F74N,602 pinout, N74F74N,602 application, or N74F74N,602 equivalent, key selection considerations include asynchronous set/reset behavior, propagation delay (3.8–9.2ns), setup/hold timing (2.0ns/1.0ns), fan-out capability (50/33), and industrial-grade reliability under 5V ±10% supply.
Technical Context
The N74F74N,602 implements two independent D-type flip-flops with fully asynchronous active-low set (SD) and reset (RD) inputs, each responding on the low-to-high clock transition. Its TTL-compatible input thresholds (VIH = 2.0V, VIL = 0.8V) and totem-pole outputs support direct interfacing with 74F-family logic.
Propagation delays are specified separately for clock-to-output (tPLH/tPHL = 3.8–9.2ns) and set/reset-to-output (3.2–10.5ns), with defined recovery time (trec = 2.0ns) between asynchronous control and subsequent clock edges-enabling robust metastability management in multi-clock-domain systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5V to 5.5V - ensures compatibility with standard 5V TTL systems and tolerates ±10% rail variation. |
| Max Clock Frequency | 125MHz at 25°C - supports high-speed synchronous logic in industrial controllers and test equipment. |
| Propagation Delay (CP→Q) | 3.8ns typical, 9.2ns max - defines minimum clock period and critical path timing budget. |
| Setup/Hold Time | 2.0ns setup / 1.0ns hold - constrains data stability window before and after clock edge for reliable sampling. |
| Output Drive | –1mA IOH / 20mA IOL - enables direct driving of up to 50 FAST unit loads (high) or 33 (low) without buffering. |
| Operating Temperature | –40°C to +85°C - qualifies for industrial environments including motor drives and factory automation. |
| Input Clamp Voltage | –1.2V - protects against negative transients during hot-plug or ESD events. |
Pinout & Package
Package: 14-pin plastic dual in-line package (DIP), SOT27-1 footprint, 300 mil width, through-hole mountable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 | SD0, SD1 | Asynchronous set (active low) - forces Q = H / Q̅ = L independently of clock; requires ≥4.0ns pulse width. |
| 2, 12 | D0, D1 | Data inputs - sampled on rising clock edge when SD/RD inactive; must be stable ≥2.0ns before CP edge. |
| 3, 11 | CP0, CP1 | Positive-edge clock inputs - triggers synchronous load; low-to-high transition initiates sampling of D inputs. |
| 4, 10 | RD0, RD1 | Asynchronous reset (active low) - forces Q = L / Q̅ = H independently of clock; requires ≥4.0ns pulse width. |
| 5, 9 | Q0, Q1 | True outputs - reflect stored D value after clock edge or asynchronous set/reset assertion. |
| 6, 8 | Q̅0, Q̅1 | Complementary outputs - inverted logic of corresponding Q outputs; usable as feedback or differential signaling. |
| 7 | GND | Ground reference - common return for all internal circuitry and I/O; must be low-impedance connection. |
| 14 | VCC | Power supply - supplies 5V ±10% to internal logic; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent flip-flops | Two fully isolated DFFs share only VCC/GND - enables compact dual-channel register or toggle logic without inter-coupling. |
| Asynchronous set/reset | SD/RD operate independently of clock and override synchronous operation - essential for power-on initialization and fault recovery. |
| TTL-compatible interface | VIH = 2.0V / VIL = 0.8V and FAST unit loading - ensures seamless integration into legacy 74F-based systems without level-shifting. |
| Industrial temperature rating | –40°C to +85°C operation - certified for deployment in harsh environments including PLCs, motor controllers, and instrumentation. |
| Low propagation skew | tPLH/tPHL matching ≤0.6ns (typ) - minimizes timing uncertainty between Q/Q̅ outputs for clean clock distribution or edge detection. |
Applications
| Industrial PLC Input Latching | Digital Test Equipment Pattern Generation |

Use Value: Identical pinout (SOT27-1/DIP14), same logic symbol, and TTL-compatible thresholds allow direct replacement; 11.5mA ICC reduces thermal load vs. 74S74. |
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 |
|---|---|---|---|
| SN74F74N | Identical electrical specs, same DIP-14 package, TI-branded version of same 74F74 design; identical AC/DC parameters and pinout. | No functional difference; suitable for multi-source procurement but subject to TI's lifecycle policies. | Select SN74F74N when dual-sourcing from TI is required; verify packaging date codes match Nexperia's industrial qualification. |
| 74ACT74PC | Higher VCC range (4.5–5.5V), CMOS input (1µA IIH), lower ICC (4mA typ), but slower fmax (110MHz) and no industrial temp option (0°C to +70°C only). | Limited to commercial-temperature applications; superior noise immunity and lower power, but unsuitable for extended ambient ranges. | Choose 74ACT74PC only for low-power, noise-sensitive commercial designs where 110MHz suffices and industrial temp is not needed. |

The N74F74N,602 specifies VIH (high-level input voltage) as 2.0V minimum and VIL (low-level input voltage) as 0.8V maximum under recommended operating conditions (VCC = 4.5–5.5V). These TTL-compatible thresholds ensure interoperability with legacy 74F, 74LS, and 74S logic families without level translation.
Can the N74F74N,602 be used in industrial temperature environments?
Yes, the N74F74N,602 is qualified for industrial temperature operation from –40°C to +85°C, as confirmed in its ordering information and absolute maximum ratings. This makes it suitable for deployment in motor drives, factory automation, and outdoor instrumentation where ambient thermal extremes are expected.
What is the output drive capability of the N74F74N,602?
The N74F74N,602 provides high-level output current (IOH) of –1mA and low-level output current (IOL) of 20mA per output, enabling it to drive up to 50 FAST unit loads in the high state and 33 in the low state. This eliminates the need for external buffers in most 74F-system interfacing scenarios.
