Product details
Overview
74VHC00SJX from Fairchild Semiconductor is a quad 2-input NAND gate in 14-lead SOP (EIAJ TYPE II, 5.3mm wide) packaging, operating across 2.0V–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 embedded systems.
For engineers reviewing the 74VHC00SJX 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, low dynamic noise (VOLP ≤ 0.8V), and compatibility with 74HC00 logic families.
Technical Context
The 74VHC00SJX implements four independent 2-input 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 application of 0V–7V signals regardless of VCC, enabling robust interfacing between 3V and 5V domains.
It supports dual-supply system operation (e.g., battery backup), features rail-to-rail input voltage range (0V to VCC), and guarantees DC performance over –40°C to +85°C with propagation delays specified at CL = 15pF and CL = 50pF loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND - provides four independent gate functions per package for compact combinational logic design |
| Propagation Delay | 3.7ns typical at VCC = 5.0V, CL = 15pF - enables high-speed timing-critical control paths in digital systems |
| Supply Voltage Range | 2.0V to 5.5V - supports operation across 3.3V and 5V logic domains without level shifters |
| Output Drive | ±8mA at VCC = 4.5V - sufficient to drive multiple CMOS inputs or small capacitive loads directly |
| Input Voltage Tolerance | –0.5V to +7.0V - prevents damage during hot-insertion or mismatched supply conditions |
| Quiescent Current | 2µA max at TA = 25°C - enables ultra-low static power in battery-powered or standby-mode circuits |
| Noise Immunity | 28% VCC minimum (VIH/VIL hysteresis) - ensures reliable switching in electrically noisy industrial environments |
Pinout & Package
74VHC00SJX is housed in a 14-lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm wide (Package Code M14D), with standard 1.27mm lead pitch and gull-wing terminations compatible with reflow soldering.
| 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 independent NAND inputs; each pair drives one gate; all inputs tolerate –0.5V to +7.0V |
| 3, 6, 10, 11 | Outputs (Y1–Y4) | CMOS-compatible push-pull outputs capable of sourcing/sinking ±8mA at 4.5V |
| 7 | GND | Ground reference for all logic and power domains; must be connected to system common ground |
| 14 | VCC | Positive supply rail (2.0V–5.5V); powers all four gates and internal protection circuitry |
Key Features
| Feature | Design Value |
|---|---|
| High-speed CMOS architecture | 3.7ns tPD at 5V - matches TTL speed while retaining CMOS power efficiency |
| Input protection circuitry | 0V–7V input tolerance independent of VCC - eliminates need for external clamping diodes |
| Power-down input safeguard | All inputs protected against floating states - prevents unintended current paths when VCC = 0 |
| Low dynamic output noise | VOLP ≤ 0.8V at CL = 50pF - reduces crosstalk and signal integrity issues in dense PCB layouts |
| Pin/function compatibility | Direct replacement for 74HC00 - enables drop-in upgrade path with no layout or firmware changes |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC00N | Slower tPD (15ns typ. at 5V), higher ICC (40µA max), narrower input voltage margin (0V–VCC only) | Limited to single-supply 5V systems; not suitable for 3V operation or mixed-voltage interfaces | Select when cost sensitivity outweighs speed/power requirements and system operates exclusively at 5V |
| SN74LVC00APWR | Lower VCC range (1.65V–5.5V), higher speed (3.5ns typ.), but no input overvoltage tolerance beyond VCC + 0.5V | Requires external clamping for >5.5V inputs; unsuitable for hot-swap or battery-backup scenarios with voltage mismatch | Prefer for ultra-low-voltage (1.8V) designs where input overvoltage protection is not required |
Compared with 74VHC00SJX, 74HC00N trades speed and power efficiency for legacy compatibility, while SN74LVC00APWR extends low-voltage operation but removes the critical ±7V input tolerance - making 74VHC00SJX uniquely suited for robust mixed-supply and industrial interface roles.

FAQ
What is the maximum input voltage rating for the 74VHC00SJX?
The 74VHC00SJX supports DC input voltages from –0.5V to +7.0V, independent of VCC level. This allows safe interfacing with higher-voltage signals (e.g., 5V inputs into a 3.3V-powered system) without external protection components. The specification is guaranteed per Absolute Maximum Ratings and validated across temperature.
Is the 74VHC00SJX pin-compatible with the 74HC00 series?
Yes, the 74VHC00SJX is pin- and function-compatible with the 74HC00 family. It uses identical pin assignments (14-pin SOP), truth table behavior, and logic function mapping. This enables direct substitution in existing 74HC00 designs without PCB or schematic modifications.
What is the typical propagation delay of the 74VHC00SJX at 3.3V supply?
At VCC = 3.3V ± 0.3V and CL = 15pF, the 74VHC00SJX exhibits a typical propagation delay (tPLH/tPHL) of 5.5ns. This value is specified in the AC Electrical Characteristics table and confirmed across –40°C to +85°C operating range.
Does the 74VHC00SJX require pull-up or pull-down resistors on unused inputs?
Yes - per Recommended Operating Conditions, all unused inputs on the 74VHC00SJX must be terminated to either VCC or GND. Floating inputs are prohibited, as they may cause excessive ICC, unpredictable output states, or increased susceptibility to noise-induced switching.
What package type does the 'SJX' suffix indicate for the 74VHC00SJX?
The 'SJX' suffix denotes the 14-lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm wide (JEDEC MO-153 not applicable; EIAJ TYPE II is distinct), with tape-and-reel packaging ('X' suffix). This package has 1.27mm lead pitch and gull-wing leads suitable for surface-mount assembly.
