Product details

Overview

MC74AC00D from onsemi is a quad 2-input NAND gate in high-performance silicon-gate CMOS technology, operating across 2.0–6.0 V supply range with ±24 mA output drive, 9.5 ns max propagation delay at 5.0 V, and guaranteed operation from −55 °C to +125 °C - used for digital logic level translation and combinatorial control in industrial PLC I/O modules.

For engineers reviewing the MC74AC00D datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (SOIC-14), exact DC/AC electrical limits, JEDEC-compliant noise immunity, Pb-free compliance, and validated alternatives for drop-in or functional replacement scenarios.

Technical Context

The MC74AC00D implements four independent NAND gates using silicon-gate CMOS process, delivering rail-to-rail output swing and high noise margin (>40% of VCC) across its full 2–6 V operating range. Its input structure meets JEDEC Std. 7A, with VIH/VIL thresholds scaling linearly with VCC (e.g., VIH = 2.1 V min at VCC = 3.0 V).

Propagation delay is characterized under CL = 50 pF and tr/tf = 3.0 ns, with tPLH/tPHL specified down to 1.0 ns typical at 5.0 V. Quiescent ICC remains ≤40 µA over temperature, and dynamic output current capability supports 24 mA sink/source per gate without latch-up up to 150 °C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Quad 2-input NAND gate - enables compact implementation of Boolean logic, enable/disable control, and signal inversion in multi-channel systems.
Supply Voltage Range	2.0 V to 6.0 V - supports mixed-voltage interfacing between 3.3 V and 5 V domains without level shifters.
Output Drive	±24 mA per gate - sufficient to directly drive LEDs, small relays, or TTL inputs while maintaining VOH ≥2.9 V / VOL ≤0.1 V at VCC = 3.0 V.
Propagation Delay	Max 9.5 ns at VCC = 5.0 V, CL = 50 pF - ensures timing-critical combinational paths meet sub-10 ns budget in control logic.
Operating Temperature	−55 °C to +125 °C - qualified for extended industrial and automotive under-hood applications requiring wide thermal margin.
Input Leakage	≤1.0 µA at VCC = 5.5 V - minimizes static power in battery-backed or low-power sleep states.
ESD Rating	>2000 V HBM - provides robust handling during board assembly and field service without external protection.

Pinout & Package

MC74AC00D is packaged in SOIC-14 (Case 751A), a 14-pin surface-mount plastic small-outline integrated circuit with 1.27 mm pitch, 8.75 mm × 3.90 mm body, and Pb-free finish (G suffix). Pin 1 is index-marked; pin 7 is GND; pin 14 is VCC.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 9, 10, 12, 13	Input A/B of NAND gates	Eight total inputs (A1/B1 through A4/B4) - each pair feeds one NAND gate; high-impedance CMOS inputs draw <1 µA.
3, 6, 8, 11	Output Y1–Y4	Four buffered NAND outputs - rail-to-rail swing, capable of sourcing/sinking 24 mA while maintaining VOL ≤0.1 V / VOH ≥2.9 V.
7	GND	Ground reference for all logic and power - must be low-inductance connection to minimize switching noise coupling.
14	VCC	Positive supply - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable AC performance.

Key Features

Feature	Design Value
High Noise Immunity	CMOS input threshold ratio >40% VCC - rejects transient noise up to 1.2 V on 3 V rails without false triggering.
Pb-Free & RoHS Compliant	Meets JEDEC Std. 7A and EU RoHS Directive - eliminates lead-based solder compatibility concerns in modern assembly lines.
Low Quiescent Current	ICC ≤40 µA at VCC = 5.5 V - enables use in always-on monitoring circuits with µA-level standby budgets.
Wide Voltage Operation	Functional from 2.0 V (battery-depleted) to 6.0 V (overvoltage-tolerant) - simplifies power domain consolidation in multi-rail systems.
Latch-Up Immunity	Rated >100 mA injection at 85 °C - prevents destructive latch-up during ESD events or supply sequencing faults.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad NAND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74AC00DR	TI part with identical logic function, 2–6 V supply, ±24 mA drive, but slightly higher max tPD (10 ns vs. 9.5 ns) and different thermal resistance (120 °C/W vs. 116 °C/W).	Validated for commercial temp range only (0–70 °C); not rated for −55 °C or +125 °C operation.	Select SN74AC00DR only for cost-sensitive commercial designs where extended temperature is unnecessary.
74VHC00M	ON Semiconductor's VHC variant offers lower ICC (2 µA typ) and faster tPD (7.5 ns max), but narrower 2–5.5 V supply range and reduced output drive (±8 mA).	Optimized for ultra-low-power, high-speed applications where load is capacitive only (e.g., clock distribution), not resistive loads like LEDs.	Choose 74VHC00M when minimizing static power and propagation delay is critical, and output loading is light.

Compared with SN74AC00DR and 74VHC00M, the MC74AC00D uniquely balances extended temperature support (−55 °C to +125 °C), robust ±24 mA drive, and 9.5 ns timing - making it the preferred choice for industrial and automotive control logic where reliability across environmental extremes is non-negotiable.

FAQ

What is the maximum supply voltage for MC74AC00D?

The MC74AC00D supports a DC supply voltage range of 2.0 V to 6.0 V, with absolute maximum rating of +6.5 V. Operation above 6.0 V is not recommended, and exceeding 6.5 V risks permanent damage per the datasheet's Maximum Ratings table. The MC74AC00D maintains full functionality and parameter guarantees across the entire 2.0–6.0 V range, including at 3.3 V and 5.0 V nominal rails.

Does MC74AC00D support operation at −55 °C?

Yes, the MC74AC00D is fully specified and guaranteed to operate from −55 °C to +125 °C ambient temperature. This extended temperature range is explicitly listed in the Recommended Operating Conditions table and validated across all DC and AC parameters, including propagation delay, output drive, and input thresholds - making the MC74AC00D suitable for aerospace, military, and under-hood automotive applications.

What is the pinout configuration of MC74AC00D in SOIC-14 package?

The MC74AC00D in SOIC-14 has pin 1 as A1 (first NAND input), pin 2 as B1, pin 3 as Y1 (output), pin 4 as A2, pin 5 as B2, pin 6 as Y2, pin 7 as GND, pin 8 as Y3, pin 9 as A3, pin 10 as B3, pin 11 as Y4, pin 12 as A4, pin 13 as B4, and pin 14 as VCC. This layout matches Figure 2 in the official datasheet and is consistent across all MC74AC00 variants in D-suffix packaging.

Is MC74AC00D compatible with 3.3 V logic systems?

Yes, the MC74AC00D operates natively at 3.3 V with full parameter compliance: VIH = 1.5 V min, VIL = 0.9 V max, VOH ≥2.9 V, VOL ≤0.1 V, and tPD ≤7.0 ns (typical) at VCC = 3.3 V. Its 2.0–6.0 V range and CMOS input structure ensure seamless interoperability with 3.3 V microcontrollers, FPGAs, and other logic families without level-shifting circuitry.

What does the 'D' suffix indicate in MC74AC00D?

The 'D' suffix in MC74AC00D denotes the SOIC-14 package (Case 751A), as confirmed in the Ordering Information table on page 5 of the datasheet. It distinguishes this variant from the TSSOP-14 version (MC74AC00DTR2G, suffix 'DT') and confirms Pb-free construction (G suffix embedded in ordering part numbers like MC74AC00DR2G).
