Product details
Overview
MM74HCT00MTC from onsemi is a quad 2-input NAND gate IC fabricated in advanced silicon-gate CMOS technology, offering TTL/LS pin-out and threshold compatibility, 14 ns typical propagation delay (tPLH/tPHL), ±25 mA output drive, and operation across −55°C to +125°C. It serves as a low-power, drop-in replacement for 74LS00 in digital logic interfacing between TTL, NMOS, and CMOS systems.
For engineers reviewing the MM74HCT00MTC datasheet, pinout, applications, or equivalent options, key selection considerations include its LS-compatible input thresholds (VIH = 2.0 V, VIL = 0.8 V), guaranteed 18 ns max propagation delay at 5 V/25°C, 4.5–5.5 V supply range, and TSSOP-14 package with Pb-free and halide-free construction.
Technical Context
The MM74HCT00MTC implements four independent 2-input NAND gates in a single monolithic CMOS die, with inputs protected by internal clamp diodes to VCC and GND. Its logic thresholds and DC drive capability (VOH ≥ 3.7 V at 4.0 mA, VOL ≤ 0.4 V) ensure reliable interfacing with legacy LS-TTL loads.
Designed for mixed-technology system integration, it operates over an extended industrial temperature range (−55°C to +125°C) and supports fast switching with 15 pF load capacitance. AC performance is specified at 5.0 V ±10%, with tTHL/tTLH ≤ 22 ns and CPD = 30 pF for dynamic power estimation.
Key Specifications
| Parameter | Value and Actual Design Meaning |

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 |
|---|---|---|---|
| SN74HCT00DR | SOIC-14 package (5.3 mm × 6.2 mm); identical electrical specs and timing; same VCC range and temperature grade | Preferred where board space allows larger SOIC footprint and hand-soldering is required | Select when mechanical compatibility with legacy SOIC layouts is prioritized over miniaturization |
| 74VHC00M | Higher speed (7.5 ns typ. tPD); wider VCC range (2–5.5 V); lower ICC (2 µA typ.); but reduced drive (±8 mA) | Better suited for low-voltage, ultra-low-power designs; not recommended for LS-TTL load driving | Choose for new designs targeting <2 V operation or sub-µA standby, but verify load compatibility |
Compared with SN74HCT00DR and 74VHC00M, the MM74HCT00MTC uniquely balances LS-TTL compatibility, TSSOP miniaturization, and full industrial temperature support - making it optimal for space-constrained upgrades requiring zero layout change and guaranteed legacy interoperability.

FAQ
What is the maximum operating temperature for the MM74HCT00MTC?
The MM74HCT00MTC is fully specified and guaranteed to operate from −55°C to +125°C. This extended temperature range is validated per onsemi's qualification standards and supports deployment in under-hood automotive, industrial motor drives, and outdoor infrastructure applications where ambient thermal stress exceeds commercial-grade limits. The MM74HCT00MTC maintains its 18 ns max propagation delay and VIH/VIL thresholds across this full range.
Is the MM74HCT00MTC pin-compatible with the 74LS00?
Yes, the MM74HCT00MTC is pin-out and logic-threshold compatible with the 74LS00. All 14 pins map identically: inputs, outputs, VCC, and GND occupy the same positions, and VIH (2.0 V) and VIL (0.8 V) match LS-TTL specifications. This allows direct substitution in existing designs without PCB modification - the MM74HCT00MTC retains the same functional behavior while reducing quiescent current by orders of magnitude.
What is the recommended decoupling for the MM74HCT00MTC?
A 0.1 µF ceramic capacitor placed as close as possible to the VCC (Pin 14) and GND (Pin 7) pins is the recommended decoupling for the MM74HCT00MTC. This minimizes high-frequency supply noise induced by fast CMOS switching transients. For systems with multiple MM74HCT00MTC devices or high-speed clock domains, adding a bulk 4.7 µF tantalum or aluminum electrolytic capacitor nearby further stabilizes the local 5 V rail. The MM74HCT00MTC's 30 pF CPD value informs dynamic current estimation.
Does the MM74HCT00MTC support mixed-voltage interfacing?
No, the MM74HCT00MTC is designed for 5 V nominal operation (4.5–5.5 V supply) and does not support true mixed-voltage interfacing like dual-supply level shifters. Its inputs are TTL-compatible but not 3.3 V tolerant - applying 3.3 V signals directly may result in marginal VIH margin. For 3.3 V ↔ 5 V translation, external buffering or a dedicated level shifter is required. The MM74HCT00MTC functions reliably only within its specified VCC and input voltage ranges.
What packaging and environmental compliance does the MM74HCT00MTC meet?
The MM74HCT00MTC is supplied in a Pb-free and halide-free TSSOP-14 package (Case 948G), compliant with JEDEC J-STD-020B for moisture sensitivity level 1 (MSL1) and RoHS Directive 2011/65/EU (RoHS 3). It contains no intentionally added lead, brominated flame retardants, or antimony trioxide. The marking "HCT 00A" and Pb-free indicator (microdot or "G") appear on the top surface, confirming conformance. The MM74HCT00MTC is suitable for lead-free reflow soldering profiles up to 260°C peak.
