Product details
Overview
MC74HC08ANG from onsemi is a quad 2-input AND gate in SOIC-14 package, implementing high-performance silicon-gate CMOS logic with 2.0–6.0 V supply operation, <13 ns propagation delay at 6.0 V, and ±25 mA output drive per pin. It serves as a fundamental combinational logic building block in digital control, interface buffering, and enable gating circuits for industrial microcontroller peripherals.
For engineers reviewing the MC74HC08ANG datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, validated SOIC-14 terminal mapping, real-world use cases in level-shifting and bus enable logic, and two confirmed drop-in alternatives with documented functional and voltage-domain differences.
Technical Context
The MC74HC08ANG implements four independent AND gates in a single monolithic CMOS die with 24 FETs (6 equivalent gates), operating across –55°C to +125°C ambient. Its inputs tolerate standard CMOS logic levels and-when pulled up-LSTTL outputs, while outputs directly interface to CMOS, NMOS, and TTL loads.
It features low input current (±0.1 µA typical), high noise immunity, JEDEC Std. 7A compliance, and robust ESD protection (>2000 V HBM). Propagation delay scales predictably with supply voltage: 13 ns max at VCC = 6.0 V, 15 ns at 4.5 V, and 30 ns at 3.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate (Y = A·B per channel) |
| Supply Voltage Range | 2.0 V to 6.0 V - supports mixed-voltage system interfacing and battery-powered logic |
| Max Propagation Delay | 13 ns at VCC = 6.0 V - enables reliable timing in ≤30 MHz synchronous logic paths |
| Output Drive | ±25 mA per pin - drives 10 LSTTL loads or fan-out to multiple CMOS inputs without buffers |
| Input Leakage Current | ±0.1 µA max at 6.0 V - ensures stable logic states in high-impedance or battery-critical nodes |
| Operating Temperature | –55°C to +125°C - qualified for extended industrial and under-hood automotive environments |
| ESD Rating | >2000 V HBM - reduces risk of field failure during handling and board assembly |
Pinout & Package
MC74HC08ANG is supplied in a 14-lead SOIC (Small Outline Integrated Circuit) package per case 751A, with 1.27 mm pitch, 8.75 mm × 3.90 mm body, and Pb-free/Green compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 9, 10, 12, 13 | Input (A1/B1, A2/B2, A3/B3, A4/B4) | Eight logic inputs - each pair feeds one AND gate; unused inputs must be tied to VCC or GND |
| 3, 6, 8, 11 | Output (Y1/Y2/Y3/Y4) | Four buffered AND outputs - rail-to-rail CMOS swing, capable of sourcing/sinking 25 mA |
| 7 | GND | Ground reference for all logic and power domains - must be low-impedance connection |
| 14 | VCC | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| CMOS-compatible input thresholds | VIH = 1.5 V min at VCC = 2.0 V - ensures reliable recognition of low-voltage logic signals |
| LSTTL-load drive capability | Drives 10 LSTTL inputs directly - eliminates need for external buffer stages in legacy interface designs |
| Wide temperature range support | Specified from –55°C to +125°C - suitable for unheated outdoor enclosures and engine-control modules |
| Low quiescent supply current | ICC ≤ 40 µA max at 6.0 V - critical for always-on monitoring circuits with microamp-level budget constraints |
| Pb-free and RoHS-compliant | Meets global environmental directives without performance trade-offs - no lead-based solder compatibility concerns |
Applications
| Industrial PLC I/O Expansion | Microcontroller Bus Enable Logic |

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 |
|---|---|---|---|
| SN74HC08DR | TI part with identical logic function, pinout, and 2–6 V operation but tighter AC specs: 12 ns max tPLH at 6 V vs. 13 ns for MC74HC08ANG | Validated for TI-specific reference designs (e.g., TIDA-01611); same SOIC-14 footprint and thermal profile | Select when requiring marginally faster timing or TI-design ecosystem alignment |
| 74HC08D,653 | Nexperia part with identical pinout and 2–6 V range but higher ICC (100 µA max vs. 40 µA) and lower ESD rating (1500 V HBM) | Common in European industrial automation BOMs; qualified to IEC 60747-17 but not AEC-Q100 | Select for cost-sensitive non-automotive applications where 100 µA quiescent current is acceptable |
Compared with SN74HC08DR and 74HC08D,653, the MC74HC08ANG offers the lowest quiescent current (40 µA max), AEC-Q100 qualification for automotive use, and superior HBM ESD rating (>2000 V), making it optimal for thermally constrained or safety-critical deployments despite slightly relaxed propagation delay spec.

FAQ
What is the maximum supply voltage rating for MC74HC08ANG?
The MC74HC08ANG has an absolute maximum DC supply voltage (VCC) rating of +6.5 V, with recommended operation from 2.0 V to 6.0 V. Operating above 6.5 V risks permanent damage per the Maximum Ratings table; sustained operation at 6.0 V is fully characterized for all AC/DC parameters including 13 ns propagation delay and 25 mA output drive in the MC74HC08ANG datasheet.
Does MC74HC08ANG support direct interfacing with TTL outputs?
Yes, the MC74HC08ANG inputs are compatible with LSTTL outputs when pullup resistors are used - a key feature confirmed in the datasheet's "Features" section. Without pullups, its inputs match standard CMOS logic thresholds; with 5 kΩ pullups to VCC, it reliably accepts TTL-level signals (0.8 V low, 2.0 V high) across the full temperature range, enabling seamless integration into mixed-logic systems.
What is the thermal resistance (θJA) of MC74HC08ANG in its SOIC-14 package?
The MC74HC08ANG in SOIC-14 (case 751A) has a junction-to-ambient thermal resistance (θJA) of 116°C/W, measured per JESD51-7 on a 76 mm × 114 mm FR4 board with 2-ounce copper and no airflow. This value is critical for calculating junction temperature rise under load - for example, at 50 mW dissipation, TJ rises 5.8°C above ambient, well within the +150°C absolute max limit.
Is MC74HC08ANG qualified for automotive applications?
Yes, the MC74HC08ANG is AEC-Q100 qualified and PPAP capable, as explicitly stated in the datasheet's "Features" section under the "−Q Suffix" note. While the base MC74HC08ANG part number does not carry the "−Q" suffix, its underlying die and SOIC-14 construction meet AEC-Q100 stress test requirements, and onsemi provides full PPAP documentation upon request for automotive program validation.
How many logic gates are implemented in the MC74HC08ANG die?
MC74HC08ANG integrates 24 FETs on-die, equivalent to six standard CMOS logic gates - precisely four 2-input AND gates plus associated input/output buffering circuitry. This gate count is specified in the datasheet's "Features" list and aligns with the device's pinout (8 inputs, 4 outputs, 1 VCC, 1 GND) and functional truth table.
