Product details
Overview
MC74LCX00DT from onsemi is a low-voltage CMOS quad 2-input NAND gate operating from 1.65 V to 5.5 V, featuring 5 V-tolerant inputs for mixed-voltage interfacing, 24 mA balanced output drive at 3.0 V, near-zero static supply current (10 µA), and AEC-Q100 qualification for automotive use. It serves as a logic-level translator and signal combiner in power-constrained, multi-rail digital systems.
For engineers reviewing the MC74LCX00DT datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, TSSOP-14 package details, automotive-grade reliability data, and real-world interface use cases - all grounded in the official onsemi Rev. 9 datasheet.
Technical Context
The MC74LCX00DT implements four independent 2-input NAND gates with TTL-compatible input thresholds and LVCMOS/LVTTL interoperability. Its 5 V-tolerant inputs allow direct connection to legacy 5 V logic without level shifters, while its rail-to-rail output swing supports clean signal integrity across 1.65–5.5 V operation.
Designed for high-noise immunity, it features high-impedance TTL-compatible inputs that reduce loading on upstream drivers, and balanced ±24 mA output sink/source capability at 3.0 V ensures robust fan-out into capacitive loads. Propagation delay is as low as 4.2 ns at 4.5–5.5 V, with output skew ≤1.0 ns across channels.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC00APWR | Same 1.65–5.5 V range and TSSOP-14 package, but rated only to +85 °C (not AEC-Q100); VIH/VIL thresholds differ slightly at 1.65 V. | Not qualified for automotive under-hood use; suitable for commercial-grade industrial or consumer control boards. | Select when AEC-Q100 compliance is unnecessary and cost optimization is prioritized over extended temperature validation. |
| 74AHC00PW,118 | Higher VCC max (5.5 V), but input tolerance limited to VCC + 0.5 V (no true 5 V tolerance); 8 mA drive @ 3.3 V vs. 24 mA. | Requires external clamping diodes for 5 V input interfacing; lower drive limits fan-out in noisy or high-capacitance environments. | Select only if interfacing exclusively within same-supply domain and drive requirements are ≤8 mA. |
Compared with SN74LVC00APWR and 74AHC00PW,118, the MC74LCX00DT uniquely combines AEC-Q100 qualification, true 5 V input tolerance, and 24 mA output drive in TSSOP-14 - making it the only option validated for automotive-grade mixed-voltage logic interfacing without redesign.

FAQ
What is the maximum input voltage rating for MC74LCX00DT?
The MC74LCX00DT supports DC input voltages from −0.5 V to +6.5 V, enabling safe operation with 5 V TTL signals even when powered from lower supply rails like 1.8 V or 3.3 V. This 5 V-tolerant capability is explicitly confirmed in the Absolute Maximum Ratings table and is a defining feature of the MC74LCX00DT's design.
Is MC74LCX00DT suitable for automotive applications?
Yes - the MC74LCX00DT carries the "−Q" suffix and is AEC-Q100 qualified for Grade 1 (−40 °C to +125 °C), PPAP capable, and manufactured under automotive-specific process controls. Its datasheet explicitly states qualification for automotive and other applications requiring unique site and control change requirements.
What package type does MC74LCX00DT use?
The MC74LCX00DT uses the TSSOP-14 package (Case 948G), measuring 4.4 mm × 5.0 mm with 0.65 mm lead pitch. This is confirmed in the Ordering Information table and mechanical drawings on page 7 of the official onsemi datasheet Rev. 9.
Does MC74LCX00DT have rail-to-rail output swing?
Yes - the MC74LCX00DT provides rail-to-rail output voltage swing: VOH reaches VCC − 0.1 V (min) and VOL drops to 0.1 V (max) under specified load conditions. This behavior is documented in the DC Electrical Characteristics table for IOH = −24 mA and IOL = 24 mA at VCC = 3.0 V and 4.5–5.5 V.
What is the typical propagation delay of MC74LCX00DT at 3.3 V?
At VCC = 3.0–3.6 V, the MC74LCX00DT exhibits a maximum propagation delay (tPLH/tPHL) of 5.5 ns over the full operating temperature range (−40 °C to +125 °C), as specified in the AC Electrical Characteristics table. This value is measured under standard test conditions with CL = 50 pF.
