Product details
Overview
N74F374N,602 from Philips Semiconductors is an octal positive-edge-triggered D-type flip-flop with 3-State outputs, designed for data latching and bus interface in TTL-compatible digital systems. It operates at 5 V ±10%, delivers 165 MHz maximum clock frequency, exhibits 5.0 ns typical propagation delay (CP to Qn), and supports 24 mA low-level output drive - enabling reliable interfacing with MOS memories and microprocessors.
For engineers reviewing the N74F374N,602 datasheet, N74F374N,602 pinout, N74F374N,602 application, or N74F374N,602 equivalent, key selection considerations include edge-triggered register behavior, independent 3-State output control via active-low OE, high-speed 3-State bus driving capability, and compatibility with standard 20-pin plastic DIP packaging.
Technical Context
The N74F374N,602 implements eight fully edge-triggered D flip-flops synchronized to the rising edge of the CP input, with data sampled one setup time before the LOW-to-HIGH transition. Its 3-State output buffers are decoupled from register operation, allowing independent enable/disable control via OE.
All eight outputs share a common active-low OE signal but retain individual Q-state integrity during high-impedance mode. The device meets FAST TTL logic thresholds (VIH = 2.0 V min, VIL = 0.8 V max) and guarantees glitch-free 3-State transitions during power-up/down.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Octal D-type flip-flop with 3-State outputs - stores and synchronizes 8-bit parallel data on clock rising edge |
| Max clock frequency | 165 MHz - enables high-throughput data capture in fast control and address latching applications |
| Propagation delay (CP→Q) | 5.0 ns (max, Tamb = 0–70 °C) - ensures tight timing margins in synchronous bus interfaces |
| Output drive (IOL) | 24 mA (low-level) - directly drives heavily loaded TTL/CMOS buses without external buffers |
| Supply current (ICC) | 57 mA (typical, VCC = 5 V) - balances speed and power for board-level digital logic design |
| Operating temperature | 0 °C to +70 °C - suitable for commercial-grade industrial and computing equipment |
| Input voltage thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - ensures robust noise immunity and interoperability with 5 V TTL families |
Pinout & Package
Package: 20-pin plastic dual in-line package (DIP), SOT146-1, 300 mil body width, through-hole mountable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE (Output Enable) | Active-low global control for all 3-State outputs - asserts high-impedance state when HIGH |
| 2–9 | Q0–Q7 | 3-State registered outputs - reflect stored D-input values when OE = LOW and CP edge occurs |
| 10 | GND | Ground reference for logic and power domains - required for stable DC bias and noise rejection |
| 11 | VCC | +5 V supply pin - powers internal logic and output drivers; must be decoupled locally |
| 12–19 | D0–D7 | Data inputs - sampled on rising edge of CP; hold time = 0 ns, setup time = 2.0 ns (min) |
| 20 | CP (Clock Pulse) | Rising-edge trigger input - initiates synchronous capture of D0–D7 into Q0–Q7 registers |
Key Features
| Feature | Design Value |
|---|---|
| Edge-triggered register | Positive-edge sampling eliminates metastability risk in asynchronous data paths |
| Independent OE control | Enables dynamic bus sharing without affecting internal register state or clock timing |
| Glitch-free 3-State transitions | Prevents bus contention during power sequencing - critical for hot-swap and reset-safe designs |
| FAST TTL compatibility | Meets full 74F family AC/DC specs - drop-in replaceable in legacy 74F-based systems |
| High-output drive | 24 mA sink capability supports direct connection to 15–20 TTL loads or long PCB traces |
Applications
| Microprocessor Address Latching | Bus Interface Buffering |
|---|---|

Use Scenario: Storing configuration bits for programmable logic controllers or test equipment front panels. IC Role / Device Role / Timing Role: Synchronous control register - updates internal state only on defined clock edges, rejecting noise-induced glitches. Use Value: Edge-triggered architecture prevents spurious writes; 165 MHz fmax supports real-time parameter updates in high-speed systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74F374N | Identical function, pinout, and AC/DC specs; manufactured by Texas Instruments under same FAST TTL specification | No functional deviation - validated for direct substitution in existing 74F374 designs | Select when TI-sourced supply chain alignment or dual-sourcing strategy is required |
| 74ACT374PC | Advanced CMOS (ACT) family: 5 V tolerant, lower ICC (20 mA typ), higher noise margin (VIH = 3.5 V), but slower tPLH (7.5 ns max) | Better power efficiency and noise immunity, but marginal timing fit for >120 MHz clock domains | Prefer for new low-power designs where 5 ns timing margin is not critical and VIH > 2.0 V is acceptable |
Compared with SN74F374N and 74ACT374PC, the N74F374N,602 offers identical timing and drive performance within the original Philips FAST TTL family, ensuring full backward compatibility while maintaining proven reliability in commercial-temperature industrial control and computing applications.

FAQ
What is the primary function of the N74F374N,602?
The N74F374N,602 is an octal positive-edge-triggered D-type flip-flop with 3-State outputs. It captures and holds 8-bit parallel data on the rising edge of its CP input, then presents the stored values at Q0–Q7 when OE is LOW. Its core role is synchronous data registration and bus isolation in 5 V digital systems - exactly as specified in the Philips 74F374 product data sheet.
Does the N74F374N,602 support 3.3 V operation?
No. The N74F374N,602 is rated for VCC = 4.5 V to 5.5 V only, with absolute maximum VCC = +7.0 V. Its input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and output drive characteristics are optimized for 5 V TTL logic families. Operating the N74F374N,602 at 3.3 V violates recommended conditions and risks unreliable switching or excessive ICC.
What is the minimum setup time required for D inputs relative to the CP rising edge on the N74F374N,602?
The N74F374N,602 requires a minimum setup time (tsu) of 2.0 ns for D inputs before the LOW-to-HIGH CP transition, per the AC set-up requirements table in the Philips product data. This value is guaranteed over the full 0 °C to +70 °C operating range and must be met to ensure deterministic data capture into the internal registers.
Can the N74F374N,602 outputs drive standard TTL loads directly?
Yes. The N74F374N,602 provides 24 mA low-level output current (IOL) and –3 mA high-level output current (IOH), meeting or exceeding standard TTL fan-out requirements. Each output can directly drive up to 15 standard TTL inputs (per 150-unit load rating), making it suitable for interfacing with legacy 74LS, 74S, and other 5 V logic families without external buffers.
Is the N74F374N,602 pin-compatible with the N74F373N,602?
No. Although both use the same 20-pin DIP package (SOT146-1), the N74F374N,602 uses Pin 20 as CP (clock) and Pin 1 as OE, whereas the N74F373N,602 uses Pin 20 as E (enable) and Pin 1 as OE - resulting in incompatible control signal assignments. Substituting one for the other without PCB modification will cause functional failure.
