onsemi MC74ACT10NG

Overview

MC74ACT10NG from onsemi is a triple 3-input NAND gate in high-performance silicon-gate CMOS technology, featuring TTL-compatible inputs, ±24 mA output drive capability, 5.0 V nominal supply operation, and SOIC-14 Pb-free packaging. It performs combinational logic inversion with propagation delays as low as 1.0 ns (tPLH/tPHL) at 5.0 V and 50 pF load, enabling use in digital control, address decoding, and bus interface circuits.

For engineers reviewing the MC74ACT10NG datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, package dimensions, functional role in logic families, and validated alternative options for industrial and embedded system design.

Technical Context

The MC74ACT10NG implements three independent 3-input NAND gates using advanced CMOS process technology optimized for speed-power trade-offs. Its TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensure interoperability with legacy bipolar logic while maintaining CMOS low power consumption.

Each gate supports rail-to-rail output swing, delivers ±24 mA DC output current, and operates across −40°C to +85°C ambient temperature. Propagation delay is characterized at CL = 50 pF and VCC = 5.0 V ±0.5 V, with guaranteed tPLH/tPHL ≤ 10.0 ns over full temperature range.

FAQ

What logic family does MC74ACT10NG belong to, and how does it differ from standard 74AC devices?

The MC74ACT10NG belongs to the 74ACT logic family, distinguished by TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at 5 V), unlike 74AC devices which have CMOS thresholds (VIH ≈ 3.5 V). This allows MC74ACT10NG to interface directly with 74LS and other bipolar logic without level shifters, while retaining CMOS output drive and low power consumption. The MC74ACT10NG is not interchangeable with MC74AC10 due to these input threshold differences.

Can MC74ACT10NG operate at 3.3 V supply voltage?

No, MC74ACT10NG is not rated for 3.3 V operation. Its recommended operating VCC range is strictly 4.5 V to 5.5 V, as confirmed in the "Recommended Operating Conditions" table on page 2 of the datasheet. At 3.3 V, input thresholds become undefined, output drive collapses, and timing parameters are unguaranteed. For 3.3 V systems, consider 74LVC10 or 74AHC10 instead of MC74ACT10NG.

What is the maximum capacitive load MC74ACT10NG can drive while maintaining specified propagation delay?

The MC74ACT10NG propagation delay specifications (tPLH/tPHL ≤ 10.0 ns) are guaranteed only at CL = 50 pF, as stated in the AC Characteristics table on page 4. Driving larger loads increases delay nonlinearly; for example, at CL = 100 pF, typical delay rises to ~14 ns. To maintain timing integrity, keep total net capacitance-including trace, via, and input capacitance of driven devices-below 50 pF, or add appropriate series termination if driving longer traces.

Does MC74ACT10NG support mixed-voltage interfacing-for example, driving a 3.3 V input?

Yes, MC74ACT10NG outputs meet 3.3 V logic-high requirements: VOH ≥ 4.4 V at VCC = 4.5 V ensures solid HIGH recognition by 3.3 V CMOS inputs (VIH ≥ 2.0 V). However, its 5 V output swing may exceed absolute maximum ratings of some 3.3 V devices; verify that the driven part's VI(max) ≥ 5.5 V or use a resistive divider/clamp diode if necessary. MC74ACT10NG itself does not accept 3.3 V inputs reliably due to its TTL input thresholds.

Is MC74ACT10NG pin-compatible with other 14-lead triple NAND packages like SN74LS10 or CD74HC10?

MC74ACT10NG shares the same 14-pin SOIC footprint and identical pinout (per Figure 1) with SN74LS10 and CD74HC10, making it physically mountable in the same PCB land pattern. However, electrical compatibility is conditional: it is functionally and pin-compatible with SN74LS10 (TTL inputs/outputs), but not with CD74HC10 (which has CMOS thresholds and 2–6 V VCC range). Always verify VCC, input thresholds, and timing margins before substitution.
