onsemi MC74AC10M

Overview

MC74AC10M from onsemi is a triple 3-input NAND gate logic IC in SOEIAJ-14 (JEDEC MS-012) package, operating at 2.0–6.0 V supply, delivering ±24 mA output drive, with propagation delays as low as 4.0 ns (tPHL/tPLH @ VCC = 5.0 V, CL = 50 pF), and used in digital control, address decoding, and bus interface circuits.

For engineers reviewing the MC74AC10M datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, real-world timing behavior, package mechanical data, functional alternatives, and supply-chain readiness for industrial and embedded logic design.

Technical Context

The MC74AC10M implements three independent 3-input NAND gates in a single monolithic CMOS device, compatible with both AC and ACT logic families. Its TTL-compatible input thresholds are not supported - only the MC74ACT10 variant has that feature; MC74AC10M uses standard CMOS input levels (VIH = 2.1 V min @ VCC = 3.0 V).

It operates across −40 °C to +85 °C ambient, supports 50 pF capacitive loads, and exhibits rail-to-rail output swing (VOH ≥ 2.9 V @ VCC = 3.0 V, I_OH = −24 mA; VOL ≤ 0.1 V @ I_OL = 24 mA). Input leakage remains ≤ ±1.0 μA over temperature and voltage range.

FAQ

What logic family does MC74AC10M belong to, and how does it differ from MC74ACT10?

MC74AC10M belongs to the 74AC (Advanced CMOS) logic family, characterized by CMOS input thresholds and high-speed operation. Unlike MC74ACT10, which features TTL-compatible inputs (VIH = 2.0 V min @ VCC = 4.5 V), MC74AC10M uses standard CMOS thresholds (VIH = 2.1 V min @ VCC = 3.0 V). This makes MC74AC10M unsuitable for direct interfacing with legacy TTL outputs without level shifting, whereas MC74ACT10 can accept TTL logic levels directly. Both share identical pinout and package options including MC74AC10M.

What is the maximum recommended capacitive load for MC74AC10M outputs?

The MC74AC10M is characterized and guaranteed for operation with up to 50 pF total load capacitance per output, as confirmed in the AC Characteristics table (CL = 50 pF test condition). Driving loads exceeding 50 pF will increase propagation delay nonlinearly and may cause waveform degradation or timing violations. For heavier loads, external buffer stages or series termination should be used. The MC74AC10M datasheet specifies no derating beyond this value, and all timing parameters assume CL = 50 pF.

Does MC74AC10M support 3.3 V operation, and what are its key DC parameters at that voltage?

Yes, MC74AC10M fully supports 3.3 V operation within its 2.0–6.0 V supply range. At VCC = 3.3 V, VIH is guaranteed ≥ 1.9 V (min), VIL ≤ 1.1 V (max), VOH ≥ 3.1 V (min at I_OH = −24 mA), and VOL ≤ 0.35 V (max at I_OL = 24 mA). Propagation delay increases to ~6.5 ns typical (vs 4.0 ns at 5 V), and ICC remains ≤ 40 μA. These values are extracted from the 74AC DC/AC tables in the official MC74AC10/D datasheet, confirming MC74AC10M's robustness in mixed-voltage 3.3 V systems.

Is MC74AC10M pin-compatible with other 74-series triple 3-input NAND packages like PDIP-14 or TSSOP-14?

MC74AC10M (SOEIAJ-14) shares identical pin numbering and logic function mapping with all standard 14-pin 74xx10 variants, including PDIP-14 (MC74AC10N), SOIC-14 (MC74AC10D), and TSSOP-14 (MC74ACT10DTR2). Pin 1–3 = Gate 1 inputs/outputs, Pin 4–6/8 = Gate 2, Pin 9–12 = Gate 3, Pin 7 = GND, Pin 14 = VCC. However, physical package dimensions differ: SOEIAJ-14 has 5.10 mm width vs SOIC-14's 3.90 mm, so PCB footprints are not interchangeable without layout revision. The MC74AC10M pinout itself is fully standardized.

What thermal considerations apply to MC74AC10M in continuous operation?

MC74AC10M has a maximum junction temperature (T_J) rating of 140 °C and operates over −40 °C to +85 °C ambient. Its thermal resistance θ_JA for SOEIAJ-14 is approximately 120 °C/W (typical, per onsemi package modeling). With max ICC = 40 μA and worst-case dynamic power (CPD = 25 pF), total power dissipation stays below 5 mW at 5 MHz toggle rate - resulting in negligible self-heating (<0.6 °C rise). No heatsinking is required; standard 2-layer PCB copper pour under the exposed pad (if present) is sufficient. The MC74AC10M datasheet confirms no thermal derating needed below 85 °C ambient.
