Product details
Overview
MC74VHC00D from onsemi is a quad 2-input NAND gate in SOIC-14 (Case 751A) packaging, designed for high-speed CMOS logic interfacing across 2 V to 5.5 V supply rails. It delivers 3.7 ns typical propagation delay at 5 V, supports 50 mA output drive per pin, and tolerates input voltages up to 7 V-enabling robust 3 V/5 V mixed-voltage system interoperation in digital control and signal conditioning circuits.
For engineers reviewing the MC74VHC00D datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated SOIC-14 pin mapping, confirmed DC/AC electrical specs across temperature, noise immunity metrics, and two functionally comparable alternatives with documented parameter-level differences.
Technical Context
The MC74VHC00D implements four independent NAND gates using silicon-gate CMOS technology, with three-stage internal circuitry including buffered outputs for enhanced noise immunity and stable switching. Its inputs are overvoltage-tolerant (−0.5 V to +7.0 V), allowing safe interfacing between 3 V logic domains and legacy 5 V systems without level shifters.
It operates across −55°C to +125°C with guaranteed performance at VCC = 2.0–5.5 V, exhibits balanced tPLH/tPHL propagation delays, and integrates power-down protection on all inputs to prevent latch-up during partial power sequencing. The device meets ESD standards >2000 V HBM and >200 V machine model.

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 | Lower VCC min (1.65 V), faster tPD (3.1 ns typ), but VIN max = VCC + 0.5 V only - no 7 V tolerance. | Preferred for 1.8 V systems; unsuitable where 5 V signals interface to 3.3 V supply without external clamping. | Select when operating below 2.0 V or requiring sub-3.5 ns delay; verify input protection separately. |
| 74AHC00PW,118 | Wider VCC range (2–5.5 V), identical 7 V VIN tolerance, but tPD = 4.2 ns (typ) and ICC = 4 µA (max) - higher static current. | Drop-in replacement in footprint and function; trades 0.5 ns speed for slightly higher quiescent power. | Choose for pin-compatible upgrade path where minor speed reduction is acceptable and sourcing favors Nexperia. |
Compared with SN74LVC00APWR and 74AHC00PW,118, the MC74VHC00D uniquely combines 7 V input tolerance with 3.7 ns speed and 2 µA ICC - making it optimal for mixed-voltage industrial control where robustness and low static power are prioritized over marginal speed gains.

FAQ
What is the maximum input voltage rating for MC74VHC00D?
The MC74VHC00D supports digital input voltages from −0.5 V to +7.0 V, independent of VCC. This overvoltage tolerance allows safe interfacing of 5 V signals into a 3.3 V-powered MC74VHC00D without external clamping diodes or level shifters - a key advantage in mixed-voltage system design where the MC74VHC00D serves as glue logic between disparate logic families.
Does MC74VHC00D support operation at 2.0 V supply?
Yes, MC74VHC00D is fully specified for operation at VCC = 2.0 V minimum, with guaranteed tPD ≤ 14.5 ns (at −55°C to +125°C, CL = 50 pF) and VIH ≥ 1.50 V. This makes the MC74VHC00D suitable for battery-powered applications where supply voltage may sag near 2.0 V, while maintaining functional NAND logic behavior and noise margins.
Is MC74VHC00D pin-compatible with standard TTL NAND gates?
The MC74VHC00D uses the industry-standard 14-pin SOIC layout for quad 2-input NAND gates (pin 1 = A1, pin 2 = B1, pin 3 = Y1, etc.), matching the pinout of 74LS00, 74HC00, and 74AHC00. While electrically distinct due to CMOS input structure and rail-to-rail output swing, the MC74VHC00D is functionally and physically pin-compatible - enabling drop-in replacement in existing layouts where VCC and loading conditions align.
What is the output drive capability of MC74VHC00D?
Each output of the MC74VHC00D can sink or source up to ±25 mA DC current, meeting or exceeding standard TTL fan-out requirements. At VCC = 5.0 V and IOL = 8 mA, VOL is guaranteed ≤ 0.55 V; at IOH = −8 mA, VOH is ≥ 3.70 V. This drive strength allows direct connection to LEDs, small relays, and multiple CMOS inputs without buffer stages - a core design value of the MC74VHC00D in space-constrained control logic.
How does MC74VHC00D handle power-down conditions?
The MC74VHC00D incorporates power-down protection on all inputs, preventing damaging current flow when inputs are driven while VCC is absent or below 0.8 V. This feature avoids latch-up risk during hot-plug events or partial power sequencing - a critical reliability attribute in modular systems where the MC74VHC00D may be powered independently from upstream signal sources.
