Product details
Overview
MC74ACT04NG from onsemi is a hex inverter logic IC in SOIC-14 package, featuring TTL-compatible inputs, 24 mA output drive capability, propagation delay ≤9.0 ns at 5 V/50 pF, and operation across −40°C to +85°C. It serves as a level-shifting signal inverter in digital control buses, microcontroller I/O conditioning, and clock buffering circuits.
For engineers reviewing the MC74ACT04NG datasheet, pinout, applications, or equivalent options, key selection criteria include input compatibility with TTL logic families, guaranteed 24 mA sink/source per output, SOIC-14 footprint constraints, and industrial temperature range support.
Technical Context
This device implements six independent CMOS inverters using high-performance silicon-gate technology. Each gate provides rail-to-rail output swing, operates from 4.5 V to 5.5 V supply, and exhibits symmetric tPLH/tPHL propagation delays under 50 pF load.
The MC74ACT04NG features TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V TTL outputs without level shifters. Its quiescent ICC is ≤40 µA and input leakage is ±1.0 µA maximum.

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ACT04DR | Identical logic function, TTL-compatible inputs, same 24 mA drive and 9 ns max delay; TI-manufactured, SOIC-14 package | No functional deviation - suitable for drop-in replacement where TI sourcing is preferred | Select when dual-sourcing or TI-aligned supply chain requirements apply |
| 74VHC04M | Higher VCC range (2–5.5 V), lower drive (±8 mA), slower delay (11 ns max), CMOS-only inputs (not TTL-compatible) | Requires external level shifting for TTL inputs; unsuitable for direct 74LS interface | Choose only if supply voltage flexibility below 4.5 V is required and TTL compatibility is unnecessary |
Compared with SN74ACT04DR and 74VHC04M, the MC74ACT04NG delivers identical timing and drive performance with guaranteed TTL input compatibility, making it optimal for legacy-interfacing designs where robust 5 V signal translation is essential.

FAQ
What logic family does the MC74ACT04NG belong to, and how does it differ from the 74AC variant?
The MC74ACT04NG belongs to the 74ACT logic family, distinguished by TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max). Unlike the 74AC variant - which uses CMOS-only inputs - the MC74ACT04NG interfaces directly with 74LS and other TTL outputs without external biasing. This makes MC74ACT04NG ideal for mixed-logic-system upgrades where legacy signal sources remain in place.
Can the MC74ACT04NG operate reliably at 4.5 V supply, and what are its output characteristics at that voltage?
Yes, the MC74ACT04NG is fully specified for operation at 4.5 V minimum supply. At VCC = 4.5 V, it guarantees VOH ≥ 4.4 V (at −24 mA) and VOL ≤ 0.44 V (at 24 mA), with propagation delay ≤9.0 ns (tPLH/tPHL) under 50 pF load. These parameters ensure robust noise margins and timing compliance in 5 V systems operating near lower rail limits.
Is the MC74ACT04NG pin-compatible with other hex inverters like the 74HC04 or 74LS04?
The MC74ACT04NG shares the standard SOIC-14 pinout (14-pin DIP-compatible layout) with 74HC04 and 74LS04, but electrical compatibility is limited. While pin positions match, the MC74ACT04NG requires 4.5–5.5 V supply and offers TTL-compatible inputs - unlike 74HC04 (2–6 V, CMOS inputs) or 74LS04 (4.75–5.25 V, bipolar, higher ICC). Direct substitution without verifying voltage and loading conditions may cause malfunction.
Does the MC74ACT04NG support operation across the full industrial temperature range, and what is its thermal resistance?
Yes, the MC74ACT04NG is rated for −40°C to +85°C ambient operation. Its SOIC-14 package (Case 751A) has a junction-to-air thermal resistance (θJA) of 116°C/W, enabling reliable operation without forced airflow in typical industrial enclosures. Maximum junction temperature remains within 150°C under worst-case power dissipation (≤1077 mW in still air at 25°C).
What is the ESD tolerance and latch-up immunity of the MC74ACT04NG, and how are these verified?
The MC74ACT04NG achieves >2000 V HBM and >1000 V CDM ESD ratings per JESD22-A114 and JESD22-C101 standards. Latch-up immunity exceeds 100 mA (tested per EIA/JESD78 at 85°C), ensuring robustness against transient overstress events. These specifications are validated in onsemi's qualification testing and documented in the official MC74AC04/D datasheet revision 10.
