Product details

Overview

MC74ACT08DTR2 from onsemi is a quad 2-input AND gate in TSSOP-14 package, featuring TTL-compatible inputs, 24 mA output drive capability, propagation delay ≤10 ns at 5.0 V, and operation across −40°C to +85°C. It serves as a logic-level combinatorial gate in digital control subsystems of industrial PLCs, automotive body controllers, and embedded interface modules.

For engineers reviewing the MC74ACT08DTR2 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, validated pin functions, real-world use cases, and technically grounded alternative options for production-grade logic design and BOM optimization.

Technical Context

This device implements four independent 2-input AND gates using high-performance silicon-gate CMOS technology. Its TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) enable direct interfacing with legacy 5 V TTL logic families without level shifting.

Each gate provides rail-to-rail output swing with guaranteed VOH ≥ 3.76 V and VOL ≤ 0.44 V at IOL/IOH = ±24 mA under full temperature range, supporting robust noise margins in noisy industrial environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Quad 2-input AND gate - enables parallel Boolean conjunction of four signal pairs in one IC
Supply Voltage Range	4.5 V to 5.5 V - compatible only with stable 5 V systems; not rated for 3.3 V operation
Propagation Delay	≤10.0 ns (max, TA = −40°C to +85°C, CL = 50 pF) - ensures timing-critical synchronization in sub-100 MHz digital control paths
Output Drive	±24 mA - supports driving multiple 74-series TTL loads or moderate-capacitance PCB traces without buffering
Input Compatibility	TTL-compatible - accepts standard 5 V TTL logic levels (0.8 V/2.0 V thresholds), eliminating need for external translators
Operating Temperature	−40°C to +85°C - qualified for extended industrial and automotive under-hood applications
ESD Rating	>2000 V HBM - provides baseline protection against handling-induced electrostatic discharge

Pinout & Package

TSSOP-14 (Case 948G), 4.9 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, Pb-free, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 8, 9, 12, 13	Input A/B of AND gates	Eight total inputs - two per gate (U1A–U1D); all TTL-compatible with VIH/VIL defined at 4.5–5.5 V
3, 6, 10, 11	Output Y of AND gates	Four logic outputs - each capable of sourcing/sinking 24 mA while maintaining VOH/VOL specs over full temp range
7	GND	Ground reference for all logic and power domains; requires low-impedance PCB connection to minimize switching noise
14	VCC	Positive supply terminal - must be decoupled locally with 0.1 µF ceramic capacitor to suppress high-frequency supply transients

Key Features

Feature	Design Value
TTL-compatible inputs	Enables plug-in replacement of 74LS08 in legacy 5 V systems without redesigning input interface circuitry
24 mA output drive	Drives up to 10 LSTTL loads or 15 pF capacitive load at full speed, reducing need for fanout buffers
AEC-Q100 qualified	Validated for automotive applications including body electronics and infotainment interfaces requiring PPAP compliance
Pb-free TSSOP-14	Meets RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1 for reflow compatibility
Low quiescent current	ICC ≤ 40 µA max at VCC = 5.5 V - minimizes standby power in always-on control modules

Applications

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
SN74ACT08DR	Same logic function, SOIC-14 package (Case 751A), identical AC/DC specs, same AEC-Q100 qualification	Requires PCB layout change due to larger SOIC footprint (8.75 × 3.9 mm vs. TSSOP's 4.9 × 4.4 mm)	Select when board space allows SOIC and hand-soldering or legacy reflow profiles are used
74VHC08M	Wider VCC range (2.0–5.5 V), lower drive (±8 mA), no TTL-compatible inputs (VIH = 3.33 V min at VCC = 5 V)	Not drop-in compatible with TTL sources; requires input voltage translation if interfacing with 74LS/ALS families	Select for mixed-voltage systems or ultra-low-power designs where 24 mA drive is unnecessary

Compared with SN74ACT08DR and 74VHC08M, MC74ACT08DTR2 uniquely combines TSSOP-14 miniaturization, full 5 V TTL interoperability, and automotive qualification - making it optimal for space-constrained, legacy-interface, and production-qualified designs.

FAQ

What is the recommended supply voltage range for MC74ACT08DTR2?

The MC74ACT08DTR2 is specified for operation only between 4.5 V and 5.5 V. Unlike its 74AC counterpart, it is not rated for 3.3 V or 2.0 V operation. Operating outside this range may result in undefined logic states, excessive ICC, or permanent damage. Always use a well-regulated 5 V supply with local 0.1 µF ceramic decoupling at the VCC pin of MC74ACT08DTR2.

Does MC74ACT08DTR2 support direct interfacing with standard TTL logic families?

Yes, MC74ACT08DTR2 has TTL-compatible inputs with VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 4.5–5.5 V, allowing direct connection to 74LS, 74ALS, and other legacy 5 V TTL outputs without level shifters. This compatibility is confirmed in the DC Characteristics table on page 4 of the official onsemi datasheet for MC74ACT08DTR2.

What is the maximum propagation delay of MC74ACT08DTR2 across temperature and voltage?

The maximum propagation delay for MC74ACT08DTR2 is 10.0 ns, measured at VCC = 5.0 V ±0.5 V, CL = 50 pF, and TA = −40°C to +85°C. This value applies to both tPLH and tPHL transitions and is guaranteed across the full operating range - critical for timing analysis in synchronous digital systems using MC74ACT08DTR2.

Is MC74ACT08DTR2 qualified for automotive applications?

Yes, MC74ACT08DTR2 is AEC-Q100 qualified and PPAP capable, as explicitly stated in the "Features" section of the onsemi datasheet. The "−Q" suffix variant (e.g., MC74ACT08DTR2G−Q) denotes full automotive qualification, but the base MC74ACT08DTR2 part shares the same die and qualification - confirmed by onsemi's ordering information and qualification documentation for MC74ACT08DTR2.

What package type and dimensions does MC74ACT08DTR2 use?

MC74ACT08DTR2 uses the TSSOP-14 package (Case 948G), measuring 4.9 mm × 4.4 mm × 1.2 mm with 0.65 mm lead pitch. Pin 1 is marked by a notch or dot; the package is Pb-free and rated MSL Level 1. Full mechanical drawings and soldering footprint data are provided in the "PACKAGE DIMENSIONS" section of the MC74ACT08DTR2 datasheet.
