Product details

Overview

MC74ACT00D from onsemi is a quad 2-input NAND gate in SOIC-14 package, designed for TTL-compatible 5 V digital logic systems. It delivers ±24 mA output drive, operates across 4.5–5.5 V supply, and achieves typical propagation delays of 1.5 ns (tPLH/tPHL) at 5 V with 50 pF load. It is used in address decoding, control signal generation, and bus interface logic in industrial controllers and embedded peripherals.

For engineers reviewing the MC74ACT00D datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated SOIC-14 pin mapping, confirmed AC/DC electrical specs at 5 V, JEDEC-compliant noise immunity, and direct alternatives for 5 V NAND logic replacement.

Technical Context

The MC74ACT00D implements four independent 2-input NAND gates using silicon-gate CMOS technology with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at 5 V). Its output stage supports rail-to-rail swing with guaranteed VOH ≥ 4.4 V and VOL ≤ 0.44 V under 24 mA sink/source conditions.

It meets JEDEC Std. 7A for input/output voltage levels and ESD robustness (>2000 V HBM), features low quiescent ICC ≤ 40 µA at 5.5 V, and exhibits dynamic output current capability up to ±75 mA for transient loads while maintaining logic integrity across −55°C to +125°C ambient.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Quad 2-input NAND gate - four independent gates, each implementing Y = A·B̅
Supply Voltage Range	4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL and mixed-voltage systems
Output Drive	±24 mA - sufficient to directly drive multiple 74-series inputs or small LEDs without buffering
Propagation Delay	1.5 ns (typ), 9.5 ns (max) at 5 V - enables use in high-speed control paths up to ~100 MHz toggle rate
Input Thresholds	VIH = 2.0 V min, VIL = 0.8 V max at 5 V - guarantees reliable recognition of TTL-level signals
Operating Temperature	−55°C to +125°C - qualified for extended industrial and automotive under-hood applications
ESD Rating	>2000 V HBM - reduces risk of handling damage during assembly and field service

Pinout & Package

MC74ACT00D is supplied in SOIC-14 (Case 751A) package, 8.75 mm × 3.95 mm body, 1.27 mm pitch, Pb-free, RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 8, 9, 12, 13	Input (A1/B1/A2/B2/A3/B3/A4/B4)	Eight logic inputs - paired per gate: Pins 1&2 → Gate 1, 4&5 → Gate 2, 8&9 → Gate 3, 12&13 → Gate 4
3, 6, 10, 11	Output (Y1/Y2/Y3/Y4)	Four independent NAND outputs - Pin 3 = Y1, Pin 6 = Y2, Pin 10 = Y3, Pin 11 = Y4
7	GND	Ground reference for all logic and power domains - must be low-impedance connection
14	VCC	Positive supply input - decoupling capacitor (0.1 µF) required within 10 mm of this pin

Key Features

Feature	Design Value
TTL-compatible input thresholds	VIH ≥ 2.0 V and VIL ≤ 0.8 V at 5 V - eliminates need for level-shifting when interfacing with legacy 74LS/74F systems
Rail-to-rail CMOS output swing	VOH ≥ 4.4 V and VOL ≤ 0.44 V @ 24 mA - ensures >0.4 V noise margin against 5 V logic thresholds
Low quiescent current	ICC ≤ 40 µA max at 5.5 V - supports low-power standby modes in battery-backed or energy-sensitive designs
High noise immunity	CMOS input structure with hysteresis-free but inherently high VIH/VIL separation - rejects typical board-level coupling noise
Pb-free and RoHS compliant	"G" suffix indicates lead-free termination - meets global environmental compliance requirements without derating

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad 2-input NAND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74ACT00DR	Identical logic function, same 4.5–5.5 V range and ±24 mA drive, but TI's version has slightly higher max ICC (100 µA vs 40 µA) and different AC timing (tPLH/tPHL max = 8.5 ns).	Valid for drop-in replacement where lower static power is not critical; requires revalidation of worst-case timing in >80 MHz paths.	Select SN74ACT00DR only if TI's supply chain or packaging (SOIC-14, reel) better aligns with production logistics.
74VHC00M	Wider supply range (2–5.5 V), lower drive (±8 mA), slower max delay (10.5 ns), and higher input leakage (1 µA vs 100 nA).	Suitable for low-power, multi-voltage boards but cannot drive heavy capacitive loads or replace MC74ACT00D in 24 mA fanout scenarios.	Choose 74VHC00M only when operating below 4.5 V or when ultra-low ICC (<2 µA) is prioritized over speed and drive strength.

Compared with SN74ACT00DR and 74VHC00M, the MC74ACT00D offers the best balance of low quiescent current, fast propagation, and strong output drive at 5 V - making it optimal for industrial control and automotive modules requiring deterministic timing and robust noise immunity.

FAQ

What is the maximum operating supply voltage for MC74ACT00D?

The MC74ACT00D is rated for 4.5 V to 5.5 V DC supply voltage. Exceeding 5.5 V risks permanent damage, as absolute maximum VCC is +6.5 V but operation above 5.5 V violates recommended conditions and degrades reliability. The MC74ACT00D must be powered within this 1.0 V window to guarantee specified VOH, VOL, and timing performance.

Does MC74ACT00D support mixed-voltage interfacing, such as 3.3 V inputs?

No - the MC74ACT00D is not designed for 3.3 V input compatibility. Its input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) assume a 5 V supply; applying 3.3 V logic signals may result in indeterminate switching or increased static current. For mixed-voltage systems, use a dedicated level shifter or select a 3.3 V–tolerant logic family like 74LVC.

Can MC74ACT00D drive a 50 pF capacitive load at full speed?

Yes - the MC74ACT00D AC specifications are explicitly characterized at CL = 50 pF, with tPLH/tPHL max = 9.5 ns at 5 V. This confirms its ability to maintain guaranteed timing with that load. However, layout parasitics must be minimized: keep traces short, avoid stubs, and place 0.1 µF decoupling within 10 mm of Pin 14 (VCC) to sustain performance.

Is MC74ACT00D pin-compatible with older 74LS00 or 74HC00 devices?

The MC74ACT00D shares the same SOIC-14 pinout as 74LS00 and 74HC00, but functional compatibility is limited. While pin positions match, the MC74ACT00D draws higher supply current during switching and has faster edge rates - potentially causing ground bounce or crosstalk in LS-designed PCBs. Verify layout integrity and noise margins before substitution.

What does the "D" suffix indicate in MC74ACT00D?

The "D" suffix in MC74ACT00D denotes the SOIC-14 package (Case 751A), per onsemi's ordering nomenclature. It distinguishes this variant from the TSSOP-14 version (MC74ACT00DT), which uses "DT". Both share identical logic functionality and electrical specs, but differ in thermal resistance (116°C/W vs 150°C/W) and board space requirements.
