Product details
Overview
74LCX10MX from Fairchild Semiconductor is a low-voltage triple 3-input NAND gate IC with 5V-tolerant inputs, designed for level-shifting between 3V and 5V logic domains. It operates from 2.3V to 3.6V VCC, delivers ≤4.9 ns propagation delay at 3.3V, supports ±24 mA output drive at 3.0V, and features power-down high-impedance I/O for bus isolation in mixed-voltage systems.
For engineers reviewing the 74LCX10MX datasheet, pinout, applications, or equivalent options, key selection criteria include 5V input tolerance, sub-5 ns tPHL/tPLH at 3.3V, SOIC-14 package compatibility, and guaranteed 2.3–3.6V operation with <10 µA quiescent ICC.
Technical Context
The 74LCX10MX implements three independent 3-input NAND gates using advanced CMOS process technology, enabling high-speed switching while maintaining low static power consumption. Its input structure tolerates up to 7V DC, allowing direct interfacing of 5V peripherals to 3V microcontrollers without external level shifters.
All inputs and outputs support power-down high-impedance states when VCC = 0V, and patented noise/EMI reduction circuitry minimizes switching transients. Latch-up immunity exceeds 500 mA per JEDEC JESD78, and ESD robustness meets 2000V HBM and 200V MM.

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 |
|---|---|---|---|
| SN74LVC10APW | 3.3V-only inputs (max VI = 3.6V); no 5V tolerance | Requires external clamping or level shifters for 5V interface | Preferred where full 5V tolerance is unnecessary and lower cost is prioritized |
| 74ALVC10M | Higher speed (tPD ≤3.5 ns), but only 3.6V max input voltage | Not suitable for direct 5V signal interfacing; requires redesign for mixed-voltage nodes | Chosen when maximum speed is critical and all signals remain within 3.3V domain |
Compared with SN74LVC10APW and 74ALVC10M, the 74LCX10MX uniquely supports true 5V-tolerant inputs while maintaining sub-5 ns delay and industrial temperature range-making it the only drop-in solution for legacy 5V peripheral integration into new 3.3V designs without layout changes.

FAQ
What is the maximum input voltage the 74LCX10MX can tolerate?
The 74LCX10MX supports DC input voltages up to 7.0V regardless of VCC level, enabling direct connection to 5V TTL or CMOS outputs without external protection. This 5V-tolerant feature is verified across the full −40°C to +85°C operating range and is specified in the Absolute Maximum Ratings table of the official Fairchild DS500453 datasheet.
Does the 74LCX10MX support power-down high-impedance I/O states?
Yes, the 74LCX10MX exhibits power-down high-impedance behavior on both inputs and outputs when VCC = 0V. This is explicitly documented in the Features section and DC Electrical Characteristics table, ensuring safe bus isolation during power sequencing or standby modes without risk of back-driving or leakage current paths.
What package type is used for the 74LCX10MX?
The 74LCX10MX uses a 14-lead Small Outline Integrated Circuit (SOIC) package, JEDEC MS-012 compliant, 0.150" narrow body width, with Pb-free terminations per JEDEC J-STD-020B. This matches the ordering code suffix "MX", where "M" denotes SOIC and "X" indicates tape-and-reel packaging.
What is the typical propagation delay of the 74LCX10MX at 3.3V?
The 74LCX10MX has a maximum propagation delay of 4.9 ns (tPHL/tPLH) at VCC = 3.3V ±0.3V, CL = 50pF, and TA = 25°C. Typical values are lower, but design margins must use the max specification. This delay is confirmed in the AC Electrical Characteristics table of DS500453 and applies uniformly across all three NAND gates.
Is the 74LCX10MX compatible with 2.5V logic systems?
Yes, the 74LCX10MX is fully specified down to 2.3V VCC, making it compatible with 2.5V nominal systems. At VCC = 2.5V ±0.2V, it guarantees tPD ≤5.9 ns and supports ≥8 mA output drive, satisfying timing and loading requirements for 2.5V FPGA I/O banks and ASIC glue logic.
