Product details
Overview
74LCX10SJ from Fairchild Semiconductor is a low-voltage triple 3-input NAND gate IC with 5V-tolerant inputs, operating from 2.3V to 3.6V VCC, delivering ≤4.9 ns propagation delay at 3.3V and ±24 mA output drive at 3.0V - used in mixed-voltage logic interfacing between 3V and 5V systems.
For engineers reviewing the 74LCX10SJ datasheet, pinout, applications, or equivalent options, key selection considerations include 5V input tolerance, 3.3V-compatible timing performance, high-drive capability for bus loading, and Pb-free SOP-14 packaging per EIAJ TYPE II.
Technical Context
The 74LCX10SJ implements three independent 3-input NAND gates in a single 14-pin SOP package, with all inputs rated for up to 7V DC - enabling safe connection to 5V signal sources while powered from 3.3V or 2.5V supplies. Its advanced CMOS process ensures rail-to-rail output swing and low dynamic power dissipation.
Each gate features high-impedance power-down behavior when VCC = 0V, and patented noise/EMI reduction circuitry improves signal integrity in dense PCB layouts. Input leakage is ≤±5.0 µA across 2.3–3.6V VCC, and latch-up immunity exceeds 500 mA per JEDEC JESD78.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3V to 3.6V - supports standard 2.5V/3.3V logic domains without level shifters |
| Input Voltage Tolerance | Up to 7V - allows direct interface with 5V TTL/CMOS outputs |
| tPD Max | 4.9 ns at VCC = 3.3V, CL = 50 pF - meets high-speed 3.3V system timing budgets |
| IOH/IOL | ±24 mA at VCC = 3.0V - drives multiple 3.3V CMOS loads or small capacitive buses |
| Power-Down Leakage | <10 µA - maintains low standby current when VCC is off |
| ESD Rating | HBM >2000V, MM >200V - robust handling in automated assembly environments |
Pinout & Package
Pb-Free 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3 mm wide, Package Number M14D.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 5, 6, 11 | C1, C2, C3 Inputs | Third input of each NAND gate - compatible with legacy 5V control lines |
| 7 | GND | Ground reference for all logic and I/O - must be connected for proper operation |
| 14 | VCC | Positive supply - powers internal logic; range 2.3–3.6V only |
| 8, 9, 10 | O1, O2, O3 Outputs | Active-low NAND outputs - full rail-to-rail swing, ±24 mA sink/source capability |
Key Features

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 | Same 3.3V VCC range but 5.5V input tolerance only - not 7V-rated | Suitable for 3.3V-only systems; less robust for mixed 5V/3.3V interconnect | Prefer 74LCX10SJ where legacy 5V signal sources are present |
| SN74AHC10DR | Wider VCC range (2–5.5V), but no 5V-tolerant inputs - requires external clamping for 5V inputs | Used in single-supply 5V designs; incompatible with direct 5V input interfacing | Select 74LCX10SJ when interfacing 5V peripherals to 3.3V logic without redesign |
Compared with 74LVC10PW and SN74AHC10DR, the 74LCX10SJ uniquely combines 7V input tolerance, 3.3V-speed performance, and Pb-free SOP packaging - making it the only option that eliminates level shifters while maintaining industrial-grade ESD and latch-up immunity.

FAQ
What is the maximum input voltage rating for the 74LCX10SJ?
The 74LCX10SJ supports DC input voltages up to 7V across all input pins (A1–C3), independent of VCC level. This allows direct connection to 5V logic families without external protection components. The specification is verified per Absolute Maximum Ratings in the Fairchild DS500453 datasheet and applies under both static and dynamic conditions.
Can the 74LCX10SJ operate at 2.5V VCC?
Yes, the 74LCX10SJ is fully specified for operation at 2.5V VCC (within the 2.3–3.6V range). At 2.5V, typical tPD is ≤5.9 ns with CL = 30 pF, and output drive is ≥±8 mA. All DC and AC parameters remain guaranteed per the Recommended Operating Conditions table in the official datasheet.
Does the 74LCX10SJ have 3-state outputs?
No, the 74LCX10SJ does not feature 3-state outputs - it provides standard push-pull CMOS outputs only. Each of the three NAND gates has a dedicated output pin (O1–O3) with no enable/disable control. For bus-oriented applications requiring tri-state capability, consider the 74LCX125 or 74LCX244 instead.
What is the thermal performance of the 74LCX10SJ in its SOP-14 package?
The 74LCX10SJ in Pb-free SOP-14 (M14D) package has a junction-to-ambient thermal resistance (θJA) of approximately 120°C/W under standard JEDEC test conditions. With typical ICC ≤10 µA and IOH/IOL ≤24 mA, self-heating remains negligible below 85°C ambient - no heatsinking is required in standard industrial applications.
Is the 74LCX10SJ RoHS compliant and halogen-free?
Yes, the 74LCX10SJ is Pb-free per JEDEC J-STD-020B and complies with EU RoHS Directive 2011/65/EU. Fairchild's documentation confirms halogen-free status for the M14D package variant. Full compliance documentation, including material declarations and test reports, is available through Aetrix Electronics upon request.
