Product details
Overview
MC74LCX08MELG from onsemi is a quad 2-input AND gate IC operating from 1.65 V to 5.5 V, featuring 5.0 V-tolerant inputs for mixed-voltage interfacing, 24 mA balanced output drive at 3.0 V, near-zero static supply current (10 µA), and SOIC-14 packaging. It serves as a level-shifting logic buffer in low-power embedded control and industrial I/O subsystems.
For engineers reviewing the MC74LCX08MELG datasheet, pinout, applications, or equivalent options, key selection considerations include its 5 V-tolerant input capability, LVTTL/LVCMOS compatibility, propagation delay down to 4.0 ns at 5 V, ±24 mA output drive, and AEC-Q100 qualification for automotive-grade reliability.
Technical Context
The MC74LCX08MELG implements four independent 2-input AND gates in a single monolithic CMOS structure with TTL-compatible input thresholds and rail-to-rail output swing. Its input stage accepts up to 5.5 V regardless of VCC, enabling direct connection to legacy 5 V logic without external level shifters.
Each gate exhibits matched propagation delays (tPLH/tPHL ≤ 4.0 ns at VCC = 4.5–5.5 V) and low dynamic switching noise (VOLP ≤ 0.8 V, VOLV ≥ −0.8 V under defined CL conditions). The device supports operation from −40 °C to +125 °C and meets latchup immunity >100 mA per JEDEC JESD78.

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 |
|---|---|---|---|
| SN74LVC08APWR | Lower VCC min (1.65 V same), but only 5 V-tolerant up to 5.5 V VI; 24 mA drive at 3.3 V; no AEC-Q100 rating | Targeted at commercial/industrial systems; not validated for automotive temperature cycling or PPAP | Select when cost sensitivity outweighs automotive qualification needs and 5 V tolerance is sufficient |
| 74AHC08PW,118 | Wider VCC range (2–5.5 V); higher speed (tPD = 3.7 ns @ 5 V); 8 mA drive @ 3.3 V; no 5 V-tolerant input spec | Suitable for high-speed digital logic where input voltage matching is guaranteed; lacks mixed-voltage interface capability | Select when maximum speed is critical and all upstream logic operates at same VCC |
Compared with SN74LVC08APWR and 74AHC08PW,118, the MC74LCX08MELG uniquely combines automotive qualification, true 5 V-tolerant inputs, and 24 mA drive in a single SOIC-14 package-making it the only option for AEC-Q100-compliant designs requiring robust 5 V interfacing without level shifters.

FAQ
What is the maximum supply voltage for MC74LCX08MELG?
The MC74LCX08MELG supports a DC supply voltage (VCC) from −0.5 V to +6.5 V per absolute maximum ratings, with recommended operation from 1.65 V to 5.5 V. Exceeding 5.5 V in normal operation risks parametric degradation, though transient spikes up to 6.5 V are survivable per JEDEC stress limits. Always maintain VCC within 1.65–5.5 V for guaranteed functionality and lifetime reliability.
Does MC74LCX08MELG support 5 V logic inputs when powered from 3.3 V?
Yes, the MC74LCX08MELG features 5 V-tolerant inputs rated to VI = −0.5 V to +6.5 V, allowing safe connection of 5.0 V TTL outputs even when VCC = 3.3 V or lower. This eliminates the need for external level shifters in mixed-voltage systems and is confirmed in the datasheet's "5.0 V Tolerant Inputs" feature and VI specification.
What is the output drive capability of MC74LCX08MELG at 3.0 V?
At VCC = 3.0 V, the MC74LCX08MELG delivers ±24 mA output sink/source current, verified in the DC Electrical Characteristics table under VOH/VOL test conditions. This enables direct driving of multiple LVTTL loads or capacitive traces up to 50 pF while maintaining specified VOL ≤ 0.4 V and VOH ≥ 2.4 V.
Is MC74LCX08MELG qualified for automotive applications?
Yes, the MC74LCX08MELG is AEC-Q100 qualified and PPAP capable, as explicitly stated in the datasheet's Features section and Ordering Information table (e.g., MC74LCX08DTR2G−Q variant). It meets automotive reliability requirements including temperature cycling, humidity testing, and latchup immunity >100 mA.
What package type does MC74LCX08MELG use?
The MC74LCX08MELG uses a 14-lead SOIC (Small Outline Integrated Circuit) package per case outline 751A, with dimensions 8.55–8.75 mm × 3.80–4.00 mm, 1.27 mm lead pitch, and Pb-free (RoHS-compliant) finish. This is confirmed in the Ordering Information table and Mechanical Case Outline drawings on pages 2 and 7 of the datasheet.
