Product details
Overview
74LCX10SJX from Fairchild Semiconductor is a low-voltage triple 3-input NAND gate IC with 5V-tolerant inputs, operating at 2.3–3.6 V supply, delivering 4.9 ns max propagation delay at 3.3 V, ±24 mA output drive at 3.0 V, and designed for level-shifting between 3V logic and legacy 5V systems in digital interface circuits.
For engineers reviewing the 74LCX10SJX datasheet, pinout, applications, or equivalent options, key selection criteria include input voltage tolerance (up to 7 V), guaranteed 3.3 V AC timing, power-down high-impedance I/O states, ESD robustness (2000 V HBM), and JEDEC-compliant Pb-free SOP packaging.
Technical Context
The 74LCX10SJX implements three independent 3-input NAND gates using advanced CMOS process technology, enabling interoperability between 3.3 V and 5 V domains without external level shifters. Its inputs tolerate up to 7 V DC, satisfying mixed-voltage system interfacing requirements while maintaining rail-to-rail output swing referenced to VCC.
It features patented noise/EMI reduction circuitry and supports power-down mode with high-impedance inputs and outputs when VCC = 0 V. Latch-up immunity exceeds 500 mA per JEDEC JESD78, and it meets JEDEC J-STD-020B for Pb-free reflow compatibility.

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC10PW,118 | Lower ICC (1 µA typ), slightly slower tPD (5.5 ns @ 3.3 V), same 5 V-tolerant inputs | Preferred for ultra-low-power portable medical devices where quiescent current dominates thermal budget | Select when sub-µA standby current is mandatory and 0.6 ns timing margin is acceptable |
| SN74LVC10APW | Same electrical specs, but requires TI-specific thermal pad layout; no latch-up rating published | Suitable for TI-centric designs with existing LVC footprint libraries and thermal management plans | Choose only if leveraging TI's design ecosystem and validated PCB stack-up guidelines |
Compared with 74LCX10SJX, the 74LVC10PW offers lower static power but looser AC timing, while SN74LVC10APW matches performance but lacks published latch-up immunity-making 74LCX10SJX preferable for industrial environments with high ESD or ground fault risk.

Manufacturer
Fairchild Semiconductor was a U.S.-based designer of high-performance analog and mixed-signal semiconductors, acquired by ON Semiconductor in 2016; its legacy logic portfolio remains widely deployed in industrial and automotive systems.
The LCX family-including 74LCX10SJX-was engineered specifically for low-voltage, high-speed, mixed-voltage digital interfacing in space-constrained embedded systems with stringent EMI and reliability requirements.
FAQ
What is the maximum input voltage the 74LCX10SJX can safely withstand?
The 74LCX10SJX supports DC input voltages up to 7 V regardless of VCC level, enabling direct connection to 5 V buses without external protection. This specification is guaranteed across the full operating temperature range (−40°C to +85°C) and is validated per Absolute Maximum Ratings in the official Fairchild datasheet DS500453.
Does the 74LCX10SJX support power-down mode with high-impedance I/O?
Yes, the 74LCX10SJX enters a power-down state when VCC = 0 V, placing both inputs and outputs in high-impedance mode. This behavior is explicitly documented in the Features section of DS500453 and allows safe hot-plug operation in backplane or modular systems without signal contention.
What package type does the 74LCX10SJX use, and is it RoHS compliant?
The 74LCX10SJX uses a Pb-Free 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3 mm wide (package number M14D), and complies with JEDEC J-STD-020B for lead-free reflow soldering. It is RoHS compliant and marked with appropriate environmental labeling per Fairchild's documentation.
Can the 74LCX10SJX drive standard TTL loads?
Yes, the 74LCX10SJX delivers ±24 mA output drive at VCC = 3.0 V, sufficient to directly drive up to 10 LS-TTL inputs (each requiring 0.4 mA high-level and 1.6 mA low-level current). This capability is confirmed in the DC Electrical Characteristics table of DS500453 under IOH/IOL specifications.
Is the 74LCX10SJX pin-compatible with other members of the LCX family?
Yes, the 74LCX10SJX shares identical pinout and logic function with other LCX10 variants including 74LCX10M (SOIC) and 74LCX10MTC (TSSOP); all use the same 14-pin arrangement with A/B/C inputs and O outputs mapped identically per gate. This uniformity simplifies footprint reuse across package options.
