Product details
Overview
N74F08D,623 from NXP Semiconductors (formerly Philips Semiconductors) is a quad two-input AND gate logic IC in a 14-pin SOIC package, operating at 5.0 V ±10%, with typical propagation delay of 4.1 ns and total supply current of 7.1 mA. It delivers four independent AND functions in industrial temperature range (–40°C to +85°C), used for digital signal conditioning and combinational logic in embedded control subsystems.
For engineers reviewing the N74F08D,623 datasheet, N74F08D,623 pinout, N74F08D,623 application, or N74F08D,623 equivalent, key selection criteria include propagation delay consistency across all four gates, guaranteed industrial-temperature operation, SOIC-14 mechanical compatibility, and TTL-compatible input/output voltage thresholds.
Technical Context
The N74F08D,623 implements standard positive-logic AND functionality with non-inverting outputs and totem-pole output stages. Each gate accepts two inputs (Dna/Dnb) and drives one output (Qn), supporting fan-out of 50/33 (high/low) under FAST unit load definition.
It operates within strict DC electrical limits: VIH ≥ 2.0 V, VIL ≤ 0.8 V, VOH ≥ 2.7 V (IOH = –1 mA), VOL ≤ 0.50 V (IOL = 20 mA), and ICC ≤ 12.9 mA (ICCL at VCC = 5.5 V, VIN = GND).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate; four independent gates with identical truth table behavior |
| Propagation Delay (tPLH/tPHL) | Typ. 4.1 ns at VCC = 5 V, CL = 50 pF; ensures sub-5 ns timing in synchronous logic paths |
| Supply Voltage Range | 4.5 V to 5.5 V; compatible with standard 5 V TTL/CMOS mixed-signal systems |
| Operating Temperature | –40°C to +85°C; qualified for industrial-grade embedded and control applications |
| Output Drive Capability | IOL = 20 mA, IOH = –1 mA; sufficient to drive multiple 74F inputs or small LED loads directly |
| Input Loading | 1.0 FAST unit load (20 µA high / 0.6 mA low); enables predictable fan-out calculation |
Pinout & Package
Package: 14-pin plastic small outline (SO), body width 3.9 mm, SOT108-1 footprint, surface-mount compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 9, 10, 12, 13 | Data inputs (D0a/D0b, D1a/D1b, D2a/D2b, D3a/D3b) | Eight dedicated TTL-compatible inputs - two per AND gate |
| 3, 6, 8, 11 | Outputs (Q0, Q1, Q2, Q3) | Four totem-pole outputs, each sourcing/sinking specified current per gate |
| 7 | GND | Ground reference for all internal logic and I/O; must be low-impedance connection |
| 14 | VCC | Positive supply rail; decoupling capacitor required near pin for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Industrial temperature rating | Guaranteed operation from –40°C to +85°C without derating or thermal monitoring |
| Low propagation delay variation | Max tPLH/tPHL spread ≤ 1.3 ns across all four gates at nominal conditions |
| TTL-compatible input thresholds | VIH = 2.0 V min and VIL = 0.8 V max ensure interoperability with legacy 74LS/74F families |
| Controlled output rise/fall times | Tr/Tf < 2.5 ns (10%–90%) enables clean edge integrity in 25 MHz+ clock domains |
Applications
| Industrial PLC I/O Conditioning | Legacy Bus Signal Gating |
|---|---|
Use Scenario: Isolating and enabling discrete sensor inputs before feeding into microcontroller GPIO banks in programmable logic controllers. IC Role / Device Role / Timing Role: Quad AND gate performing enable-controlled signal pass-through with deterministic 4.1 ns latency per path. Use Value: Eliminates need for software-based gating; preserves real-time response by offloading combinatorial logic to hardware. | Use Scenario: Enabling data transfer between parallel address/data buses in retro-computing or test equipment backplanes. IC Role / Device Role / Timing Role: Synchronizing bus access via chip-select AND logic with sub-5 ns propagation to avoid setup/hold violations. Use Value: Maintains timing margin in 10–20 MHz bus cycles where software-controlled delays are too variable. |
| Power Sequencing Control | Digital Test Fixture Logic |
Use Scenario: Generating power-good enable signals only when multiple voltage rails (e.g., +5 V, +3.3 V, –12 V) are simultaneously stable. IC Role / Device Role / Timing Role: Four-input AND function synthesized using two cascaded gates (e.g., D0a/D0b → Q0; Q0/D1a → Q1), with verified worst-case delay stack. Use Value: Provides fail-safe sequencing without microcontroller dependency or external RC timing components. | Use Scenario: Implementing stimulus-response logic in automated test equipment for validating digital ICs on wafer or board level. IC Role / Device Role / Timing Role: Generating expected output patterns from known input combinations during functional testing. Use Value: Enables deterministic, repeatable test vectors with nanosecond-level timing repeatability across temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74F08DR | TI part; identical AC/DC specs, same SOIC-14 package, but rated only for 0°C to +70°C commercial range | Lacks industrial temperature qualification; unsuitable for uncontrolled ambient environments | Select only if system ambient stays within 0–70°C and cost sensitivity outweighs reliability margin |
| 74ACT08SO14 | Advanced CMOS variant; 3.3 V/5 V tolerant, lower ICC (2 µA typ), but higher VOL (0.55 V max at IOL = 24 mA) | Higher noise margin but incompatible with 74F-level drive strength; requires level-shifting in mixed-voltage systems | Prefer when migrating to lower-power designs with compatible voltage rails and no legacy 74F loading requirements |
Compared with SN74F08DR and 74ACT08SO14, the N74F08D,623 uniquely combines industrial temperature operation, 74F-family drive strength, and proven 4.1 ns propagation stability-making it the sole choice for legacy-replacement or harsh-environment 5 V logic systems requiring drop-in compatibility and long-term supply continuity.

Manufacturer
NXP Semiconductors is a global semiconductor company formed from the spin-off of Philips Semiconductors in 2006, specializing in secure connectivity solutions for automotive, industrial, and IoT markets.

FAQ
Is N74F08D,623 pin-compatible with other 74F08 variants like N74F08N?
Yes, N74F08D,623 shares identical pinout and logic function with all 74F08 variants including N74F08N (DIP-14) and I74F08D (industrial SO-14). The 'D' suffix denotes SOIC packaging, while 'N' indicates DIP; both use the same internal die and pin mapping per SOT108-1 and SOT27-1 drawings.
What is the maximum capacitive load this device can drive reliably?
The N74F08D,623 is characterized up to 50 pF load capacitance with RL = 500 Ω, delivering 4.1 ns typical propagation delay. Driving >50 pF increases delay nonlinearly and may cause ringing; for >100 pF loads, external series termination or buffer staging is recommended per Philips AC Electrical Characteristics test conditions.
Can N74F08D,623 operate at 3.3 V supply?
No. The device is specified only for VCC = 4.5 V to 5.5 V. At 3.3 V, VIH and VOL specifications are not guaranteed, and propagation delay increases significantly beyond datasheet limits. Use 74LVC08 or 74ACT08 for 3.3 V operation with compatible logic levels.
Does this part support hot-swap or live-insertion?
No. N74F08D,623 lacks hot-swap protection features such as power-up reset, Ioff, or bus-hold. Applying VCC before GND or inserting into a live backplane risks latch-up due to absolute maximum ratings being exceeded (e.g., VIN > VCC + 0.5 V). Always power-rail sequence and insert only in de-energized systems.
