Product details
Overview
MC74ACT08ML1 from onsemi is a quad 2-input AND gate IC with TTL-compatible inputs, operating at 4.5–5.5 V supply, delivering ±24 mA output drive, and featuring 9.0 ns max propagation delay (5 V, CL = 50 pF). It is used in digital logic interfacing, bus gating, and control signal conditioning in industrial controllers and embedded system I/O stages.
For engineers reviewing the MC74ACT08ML1 datasheet, pinout, applications, or equivalent options, key selection criteria include its 5 V operation, TTL input compatibility, guaranteed 24 mA sink/source capability, AC/ACT family logic level alignment, and EIAJ-14 (CASE 965) surface-mount package.
Technical Context
The MC74ACT08ML1 implements four independent AND gates in a single monolithic CMOS structure, designed for 5 V systems with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max). Its output stage supports rail-to-rail switching with symmetrical drive strength.
It complies with the 74ACT logic family specifications: guaranteed operation from –40°C to +85°C ambient, quiescent ICC ≤ 40 µA, and dynamic output current capability up to ±75 mA (pulse-tested), enabling robust noise immunity and fanout > 20 into standard TTL loads.

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 | SOIC-14 (D suffix), identical AC/ACT electrical specs, same 4.5–5.5 V range and ±24 mA drive | No package change required for board redesign; compatible footprint but different land pattern geometry | Select when SOIC-14 assembly infrastructure is already established and EIAJ-14 retooling is undesirable |
| 74VHC08M | VHC family: wider 2–5.5 V supply range, lower drive (±8 mA), higher VIH (3.5 V min at 4.5 V), slower delay (11 ns max) | Not suitable for TTL-level input interfacing; requires level translation if driven by legacy TTL sources | Choose only for new designs targeting ultra-low power or multi-supply voltage flexibility, not drop-in replacement |
Compared with SN74ACT08DR and 74VHC08M, the MC74ACT08ML1 offers identical logic performance with EIAJ-14 packaging optimized for high-density automated placement, while maintaining full compatibility with TTL signal sources-making it ideal for space-constrained industrial control boards where legacy interface integrity is mandatory.

FAQ
What is the recommended supply voltage range for MC74ACT08ML1?
The MC74ACT08ML1 is specified for operation from 4.5 V to 5.5 V. Operation outside this range may result in undefined logic states or degraded parametric performance. The device is not rated for 3.3 V operation, and using it at 3.3 V violates the 74ACT family's input threshold and output swing specifications. Always maintain VCC within the recommended range to ensure compliance with VOH ≥ 4.4 V and VOL ≤ 0.44 V under load.
Does MC74ACT08ML1 support TTL-level input signals?
Yes, the MC74ACT08ML1 features TTL-compatible inputs with VIH = 2.0 V minimum and VIL = 0.8 V maximum at 5 V supply, allowing direct connection to standard 5 V TTL outputs without level shifters. This compatibility is explicitly defined in the DC Characteristics table for the 74ACT variant and distinguishes it from non-TTL families like 74VHC. Input leakage remains ≤ ±1.0 µA across temperature.
What is the maximum propagation delay of MC74ACT08ML1 under typical conditions?
The MC74ACT08ML1 has a maximum propagation delay of 9.0 ns at VCC = 5.0 V and CL = 50 pF, measured from input transition (1.0 V to 2.0 V) to valid output transition. This value applies across the full operating temperature range (–40°C to +85°C) and is guaranteed in the AC Characteristics table. Typical delay is faster (≈1.0 ns), but design timing margins must be based on the 9.0 ns worst-case figure.
Can MC74ACT08ML1 drive standard TTL loads directly?
Yes, the MC74ACT08ML1 can drive standard TTL loads directly due to its ±24 mA output drive capability and rail-aligned VOH/VOL. Each output supports fanout > 20 into standard TTL inputs (IIH = 40 µA, IIL = –1.6 mA), eliminating the need for buffer stages. This capability is verified under worst-case conditions (VCC = 4.5 V, TA = +85°C) and is documented in the DC Characteristics table for IOH and IOL.
What package type does MC74ACT08ML1 use, and is it RoHS-compliant?
The MC74ACT08ML1 uses the EIAJ-14 (CASE 965) package: a 14-pin plastic leaded chip carrier with gull-wing leads. Per onsemi documentation and product change notices, this variant is RoHS-compliant and lead-free, meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) requirements. The "L1" suffix denotes lead-free finish and tape-and-reel packaging (2000 units/reel).
