Product details
Overview
74LVQ00SJX from Fairchild Semiconductor is a low-voltage quad 2-input NAND gate IC designed for 3.3 V logic systems, featuring guaranteed incident-wave switching into 75 Ω transmission lines, 10 ns typical propagation delay at 3.3 V, and simultaneous switching noise immunity. It operates across −40°C to +85°C and supports industrial control bus interfacing.
For engineers reviewing the 74LVQ00SJX datasheet, pinout, applications, or equivalent options, key selection criteria include its 2.0–3.6 V supply range, ±12 mA output drive, guaranteed output-to-output skew ≤1.5 ns, and EIAJ TYPE II SOP-14 package compatibility with high-density PCB layouts.
Technical Context
The 74LVQ00SJX implements four independent TTL-compatible 2-input NAND gates in a single monolithic CMOS structure optimized for 3.3 V operation. Its design guarantees dynamic threshold performance and simultaneous switching noise suppression under heavy capacitive loads.
AC timing is characterized with CL = 50 pF and includes tPLH/tPHL ≤10.0/8.5 ns (max) at VCC = 3.3 V ±0.3 V, and output-to-output skew tOSHL/tOSLH ≤1.5 ns - all specified over full temperature range and validated per JEDEC MS-012 and EIAJ TYPE II mechanical standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 3.6 V - enables direct interface with 3.3 V microcontrollers and FPGAs without level translation |
| VOH / VOL | ≥2.9 V / ≤0.1 V at IOUT = ±12 mA - ensures robust noise margins in noisy industrial environments |
| tPLH / tPHL | ≤10.0 / ≤8.5 ns max at 3.3 V, CL = 50 pF - supports >50 MHz toggle rates in synchronous logic paths |
| Output Skew | ≤1.5 ns - critical for time-aligned enable/control signals in multi-channel data routing |
| Input Thresholds | VIH = 2.0 V, VIL = 0.8 V at VCC = 3.3 V - compatible with LVTTL and mixed-voltage system inputs |
| Dynamic Drive | IOLD = 36 mA, IOHD = −25 mA - sustains fast edge rates on 75 Ω transmission lines without termination resistors |
| Power Dissipation | CPD = 22 pF - predicts <1.5 mW static power at 10 MHz clocking, enabling low-heat-density logic arrays |
Pinout & Package
74LVQ00SJX is housed in a 14-lead Small Outline Package (SOP), EIAJ TYPE II, 5.3 mm wide, with standard dual-in-line pin spacing and gull-wing leads suitable for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 11, 12 | Gate Inputs (A1/B1, A2/B2, A3/B3, A4/B4) | Four independent 2-input NAND gate inputs; each pair drives one output; unused inputs must be tied HIGH or LOW |
| 3, 6, 10, 13 | Gate Outputs (Y1, Y2, Y3, Y4) | Active-low open-drain–compatible CMOS outputs; capable of driving 12 mA sink/source with rail-to-rail swing |
| 7 | GND | Logic ground reference; decoupling capacitor placement adjacent to this pin minimizes ground bounce |
| 14 | VCC | Positive supply input; requires local 0.1 µF ceramic bypass capacitor between Pin 14 and Pin 7 |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed incident-wave switching | Validated into 75 Ω transmission lines - eliminates need for external series termination in video/data bus designs |
| Simultaneous switching noise immunity | Specified dynamic threshold behavior ensures stable logic levels during multi-output transitions |
| Pin-to-pin skew control | ≤1.5 ns max skew across all four outputs - enables synchronized enable/disable of parallel peripherals |
| Low-voltage 3.3 V operation | Full functionality from 2.0 V to 3.6 V - supports battery-backed or low-power standby modes |
| Industrial temperature range | −40°C to +85°C operation - qualified for use in motor drives, PLC I/O modules, and outdoor telecom equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC00APWR | Higher drive (24 mA), lower CPD (15 pF), but no guaranteed 75 Ω incident-wave switching | Better for high-speed digital logic; less suited for unterminated transmission line interfaces | Prefer when maximum speed and lowest power dominate over transmission line integrity |
| 74AHC00PW,118 | Wider VCC range (2–5.5 V), higher VOH (4.4 V @ 5 V), but no skew or dynamic threshold guarantees | Supports mixed 3.3 V/5 V systems; lacks 74LVQ00SJX's noise-immunity specs for industrial noise | Choose for legacy 5 V backplane compatibility where simultaneous switching noise is not critical |
Compared with SN74LVC00APWR and 74AHC00PW,118, the 74LVQ00SJX uniquely delivers guaranteed 75 Ω transmission line drive and ≤1.5 ns output skew - making it the only option among the three qualified for noise-critical, high-speed industrial bus enable logic without added termination components.

FAQ
What is the recommended operating voltage range for the 74LVQ00SJX?
The 74LVQ00SJX is specified to operate reliably from 2.0 V to 3.6 V. Operation outside this range may cause undefined logic states or accelerated device degradation. At 3.3 V, it delivers optimal timing performance (tPLH/tPHL ≤10.0/8.5 ns) and output drive (±12 mA), making 3.3 V the preferred nominal supply for most applications using the 74LVQ00SJX.
Does the 74LVQ00SJX support direct connection to 75 Ω coaxial transmission lines?
Yes - the 74LVQ00SJX is explicitly guaranteed for incident-wave switching into 75 Ω transmission lines across its commercial temperature range, per datasheet Note 5. This capability eliminates the need for external series termination resistors in video, serial data, or industrial bus applications where the 74LVQ00SJX drives unterminated lines.
What is the maximum output skew between any two gates in the 74LVQ00SJX?
The 74LVQ00SJX guarantees an output-to-output skew of ≤1.5 ns for both tOSHL and tOSLH, as specified in the AC Electrical Characteristics table. This tight skew tolerance applies to any pair of outputs switching in the same direction and is validated over the full −40°C to +85°C operating range - a key requirement for synchronized control signal generation in the 74LVQ00SJX.
Can unused inputs on the 74LVQ00SJX be left floating?
No - unused inputs on the 74LVQ00SJX must be externally tied HIGH (to VCC) or LOW (to GND). Floating inputs can cause increased ICC, erratic output behavior, or excessive power dissipation due to intermediate voltage states at the CMOS input stage. This requirement is explicitly stated in Note 2 of the datasheet and applies to all four NAND gate inputs in the 74LVQ00SJX.
What package type does the 74LVQ00SJX use, and is it RoHS-compliant?
The 74LVQ00SJX uses a 14-lead Small Outline Package (SOP), EIAJ TYPE II, 5.3 mm wide (Package Number M14D). While the original Fairchild datasheet predates RoHS enforcement, current production lots supplied by Aetrix Electronics meet RoHS Directive 2011/65/EU and are lead-free, with matte tin lead finish - verified via material declarations for the 74LVQ00SJX.
