Product details
Overview
74LCX04MTR from STMicroelectronics is a low-voltage CMOS hex inverter with 5V-tolerant inputs, designed for 3.3V logic systems interfacing to 5V signal environments. It delivers symmetrical output drive (±24mA at VCC = 3V), 5.2ns max propagation delay at 3V, and operates across 2.0–3.6V supply range-enabling PCI bus-level performance in portable and mixed-voltage embedded control applications.
For engineers reviewing the 74LCX04MTR datasheet, 74LCX04MTR pinout, 74LCX04MTR application, or 74LCX04MTR equivalent, key selection criteria include 5V input tolerance, rail-to-rail output swing at 3.3V, power-down protection on all I/Os, balanced tPLH/tPHL delays, and SO-14 package compatibility with legacy 74-series footprints.
Technical Context
This device implements six independent CMOS inverters using sub-micron C2MOS process technology, enabling high-speed operation with low static power. Its input structure incorporates dual-diode clamping and series resistors to sustain 5V signals while powered from 3.3V, and its output stage features matched P/N channel drive strength for consistent rise/fall times.
The IC guarantees latch-up immunity >500mA per JESD17 and ESD robustness of >2kV HBM, supporting reliable deployment in industrial control backplanes and hot-pluggable modules. All I/Os remain high-impedance during power-down (VCC = 0V), preventing bus contention in partial-power-down system states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0V to 3.6V - supports battery-backed 3.3V systems with 1.5V data retention |
| tPD (Max) | 5.2ns at VCC = 3.0–3.6V - matches AC/ACT speed at half the supply voltage |
| IOL / IOH | ±24mA at VCC = 3.0–3.6V - drives standard PCI loads without external buffers |
| Input Tolerance | 0V to 5.5V - enables direct connection to 5V TTL/CMOS outputs |
| Power-Down Protection | IOK ≤ ±50mA, IIK ≤ ±50mA - prevents damage when VCC = 0V and I/O biased to 5V |
| ESD Rating | HBM > 2000V - meets MIL-STD-883 Method 3015 for handling in non-ESD-controlled areas |
Pinout & Package
74LCX04MTR is supplied in a 14-pin SOIC (SO-14) package with 1.27mm pitch, compliant with JEDEC MS-012 and PO13G mechanical standards. Body dimensions: 8.55–8.75mm × 5.8–6.2mm × 1.75mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,3,5,9,11,13 | 1A–6A | Independent logic inputs; each accepts 0–5.5V regardless of VCC state |
| 2,4,6,8,10,12 | 1Y–6Y | Inverted outputs; actively driven HIGH/LOW with matched impedance (|IOH| = IOL) |
| 7 | GND | Reference ground for all internal circuitry and I/O clamp diodes |
| 14 | VCC | Primary supply pin; powers internal logic and output drivers; must be decoupled locally |
Key Features
| Feature | Design Value |
|---|---|
| 5V-tolerant inputs | Enables seamless interface between 3.3V logic domains and legacy 5V peripherals without level shifters |
| Symmetrical output drive | Ensures matched rise/fall times (tPLH ≅ tPHL), reducing timing skew in synchronous buses |
| Power-down I/O protection | Prevents current injection and latch-up when VCC is off but I/O lines remain active at 5V |
| Low dynamic power | CPD = 41pF at 3.3V - reduces switching current by >60% vs. equivalent 5V AC-family devices |
Applications
| Industrial PLC I/O Modules | PCI Bus Interface Logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC04APWR | Lower ICC (max 10µA), identical VCC range (1.65–3.6V), but only 5V-tolerant on inputs-not outputs | Lacks power-down protection; unsuitable where VCC may be unpowered while I/O remains live | Select when full 5V I/O tolerance is unnecessary and ultra-low static current is critical |
| 74ALVC04PW | Higher speed (tPD = 3.3ns typ), same SO-14 footprint, but no 5V-tolerant inputs-requires external clamping | Not compatible with direct 5V input interfacing; needs additional protection circuitry | Select only in pure 3.3V systems where maximum speed outweighs interface flexibility |
Compared with SN74LVC04APWR and 74ALVC04PW, the 74LCX04MTR uniquely combines 5V input tolerance, power-down I/O protection, and PCI-compliant drive strength in a single SO-14 package-making it the only choice for mixed-voltage hot-swap interfaces requiring zero external components.

FAQ
Can 74LCX04MTR safely drive a 50Ω transmission line?
No. Its output stage is rated for ±24mA into resistive loads, not 50Ω RF termination. Driving such a line would exceed VOL/VOH specs and cause excessive power dissipation. Use a dedicated line driver (e.g., SN65LVDS1) for controlled-impedance signaling.
Does 74LCX04MTR support partial power-down of individual gates?
No. Power-down protection applies globally when VCC = 0V; all six inverters enter high-Z state simultaneously. There is no per-gate enable/disable control-gates cannot be independently powered or isolated.
What is the maximum input frequency for reliable operation?
While not explicitly specified, the 5.2ns max propagation delay implies reliable operation up to ~100MHz for clean square-wave inputs with <10ns/V slew rate. For sustained high-frequency use, ensure CL ≤ 50pF and maintain proper PCB layout to minimize ringing.
Is the SO-14 package RoHS-compliant and lead-free?
Yes. The 74LCX04MTR SO-14 package is RoHS-compliant and lead-free, conforming to EU Directive 2011/65/EU. Lead finish is matte tin, and the device meets JEDEC J-STD-020 moisture sensitivity level MSL3.
