Product details
Overview
74VHC00MX from Fairchild Semiconductor is a quad 2-input NAND gate IC in 14-lead SOIC package, operating from 2.0V to 5.5V supply, delivering 3.7ns typical propagation delay at 5V, ±8mA output drive, and 2µA max quiescent current - used for logic-level translation and combinatorial control in mixed-voltage digital systems.
For engineers reviewing the 74VHC00MX datasheet, pinout, applications, or equivalent options, key selection criteria include input voltage tolerance (–0.5V to +7.0V), noise immunity (28% VCC min), power-down input protection, and compatibility with 74HC00-based designs requiring low-noise, low-power CMOS logic.
Technical Context
The 74VHC00MX implements four independent NAND gates using silicon-gate CMOS technology, with three-stage internal buffering to ensure stable output transitions and high noise immunity. Its input protection circuit allows safe operation across 0V–7V input voltages regardless of VCC, enabling robust interfacing between 3V and 5V domains.
It supports dual-supply system use (e.g., battery backup) and features dynamic noise margins (VIHD = 3.5V, VILD = 1.5V at 5V/50pF), quiet-output voltage limits (VOLP = 0.8V max), and guaranteed operation from –40°C to +85°C with 15pF–50pF load capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND - provides four independent Boolean NOT-AND gates in one package |
| Propagation Delay | 3.7ns typical at VCC = 5.0V, CL = 15pF - enables high-speed timing in synchronous logic paths |
| Supply Voltage Range | 2.0V to 5.5V - supports both 3.3V and 5V system rails without level shifters |
| Input Voltage Tolerance | –0.5V to +7.0V - prevents damage during hot-swap or supply sequencing mismatches |
| Output Drive | ±8mA at VCC = 4.5V - sufficient to drive multiple CMOS inputs or small capacitive loads |
| Quiescent Current | 2µA max at TA = 25°C - enables ultra-low static power in battery-powered or standby circuits |
| Noise Immunity | VNIH = VNIL = 28% VCC min - ensures reliable switching under EMI or ground bounce conditions |
Pinout & Package
74VHC00MX is housed in a 14-lead Small Outline Integrated Circuit (SOIC) package per JEDEC MS-012, 0.150" narrow body, with standard 1.27mm lead pitch and gull-wing terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 12, 13 | Inputs (A1/B1, A2/B2, A3/B3, A4/B4) | Four pairs of NAND gate inputs - each pair accepts independent logic signals |
| 3, 6, 10, 11 | Outputs (Y1, Y2, Y3, Y4) | Active-low NAND outputs - sink/source up to ±8mA with rail-to-rail swing |
| 7 | GND | Ground reference for all logic and power domains - must be low-impedance |
| 14 | VCC | Positive supply input - powers all four gates and internal protection circuitry |
Key Features
| Feature | Design Value |
|---|---|
| High-speed CMOS architecture | 3.7ns propagation delay at 5V matches TTL performance while retaining CMOS efficiency |
| Input overvoltage tolerance | Withstands –0.5V to +7.0V on any input regardless of VCC - eliminates need for external clamping diodes |
| Power-down input protection | Inputs remain protected and non-damaging even when VCC = 0V - critical for hot-plug or partial-power-down systems |
| Low dynamic noise | VOLP ≤ 0.8V ensures minimal ground bounce and crosstalk in dense PCB layouts |
| Pin/function compatibility | Direct replacement for 74HC00 in existing designs - no layout or firmware changes required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74VHC00DR | Same logic function, identical AC/DC specs, TI-manufactured SOIC-14 variant with identical pinout and JEDEC MS-012 footprint | No functional or interface difference - drop-in substitute with same thermal and electrical behavior | Select when sourcing from TI-authorized channels or requiring TI-specific qualification documentation |
| 74HC00D,653 | NXP variant in SOIC-14; slightly higher tPD (7ns typ. at 5V/50pF) and lower noise immunity (20% VCC) | Acceptable for non-critical timing paths but not recommended for high-noise or fast-edge applications | Choose only if cost sensitivity outweighs speed/noise requirements and legacy NXP BOM alignment is required |
Compared with SN74VHC00DR and 74HC00D,653, the 74VHC00MX delivers superior speed (3.7ns vs. 7ns), tighter noise margins (28% vs. 20% VCC), and broader input voltage tolerance (–0.5V to +7.0V), making it optimal for mixed-supply, noise-prone, or timing-critical digital interfaces.

FAQ
What is the maximum supply voltage rating for the 74VHC00MX?
The 74VHC00MX has an absolute maximum supply voltage (VCC) rating of +7.0V, though recommended operation is limited to 2.0V–5.5V. This 7V tolerance enables safe handling during transient overvoltage events or mismatched supply sequencing, but sustained operation above 5.5V voids specification compliance and may impact reliability.
Does the 74VHC00MX support 3.3V-only operation?
Yes, the 74VHC00MX fully supports 3.3V operation: VIH = 0.7 × VCC = 2.31V min, VIL = 0.3 × VCC = 0.99V max, and VOH/VOL meet 3.3V logic thresholds with margin. It drives ±8mA at 3.3V and maintains 5.5ns typical propagation delay (CL = 15pF), making it suitable for native 3.3V digital systems.
Is the 74VHC00MX pin-compatible with standard 74HC00 devices?
Yes, the 74VHC00MX is pin- and function-compatible with the 74HC00 family. Its SOIC-14 footprint (JEDEC MS-012), pin numbering, logic truth table, and terminal assignments match exactly - allowing direct substitution without PCB modification or firmware adjustment in existing 74HC00 designs.
What is the input protection capability of the 74VHC00MX?
Each input of the 74VHC00MX includes integrated protection that permits –0.5V to +7.0V applied independently of VCC, preventing damage during hot insertion, floating inputs, or supply sequencing faults. This eliminates need for external series resistors or clamps in mixed-voltage or battery-backed systems.
Can unused inputs on the 74VHC00MX be left floating?
No - unused inputs on the 74VHC00MX must be tied HIGH or LOW per datasheet requirement. Floating inputs cause increased ICC, unpredictable output states, and potential oscillation due to CMOS input stage metastability; this violates Recommended Operating Conditions and risks system-level malfunction.
