Product details

Overview

74LCX00YMTR from STMicroelectronics is an automotive-grade, low-voltage CMOS quad dual-input NAND gate in SO-14 package, operating from 2.0 V to 3.6 V, with 5 V tolerant inputs, 4.3 ns max propagation delay at 3 V, and ±24 mA output drive capability. It serves as a logic-level translation and signal inversion component in 3.3 V systems interfacing with legacy 5 V buses.

For engineers reviewing the 74LCX00YMTR datasheet, 74LCX00YMTR pinout, 74LCX00YMTR application, or 74LCX00YMTR equivalent, this device is selected for automotive infotainment power sequencing, industrial PLC I/O conditioning, and 3.3 V/5 V mixed-signal interface design where input tolerance, speed-power balance, and AEC-Q100 compliance are critical.

Technical Context

The 74LCX00YMTR implements four independent NAND gates using sub-micron C2MOS technology, enabling rail-to-rail 5 V input compatibility while operating at 3.3 V supply. Its symmetrical output impedance (|IOH| = IOL ≥ 24 mA at VCC = 3 V) ensures matched rise/fall times and low skew (≤1.0 ns).

It features built-in power-down protection on all inputs/outputs, latch-up immunity >500 mA per JESD17, and ESD robustness rated at 2000 V HBM, 200 V MM, and 1000 V CDM - essential for automotive under-hood and industrial control environments.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Operating Range	2.0 V to 3.6 V - enables direct integration into 3.3 V logic domains without level shifters.
Input Voltage Tolerance	0 V to 5.5 V - allows safe connection to 5 V TTL/CMOS sources without external clamping.
tPD (Max)	4.3 ns at VCC = 3.0–3.6 V, CL = 50 pF - matches AC/ACT family speed at half the supply voltage.
IOL / IOH (Min)	±24 mA at VCC = 3.0–3.6 V - drives standard PCI bus loads and multiple 74LVC inputs.
Propagation Skew	≤1.0 ns - ensures deterministic timing across all four gates in synchronous logic paths.
ESD Rating (HBM)	2000 V - exceeds automotive electronics stress requirements per ISO 10605.
Temperature Range	−40 °C to +85 °C - qualified per AEC-Q100 Grade 3 for under-dash automotive applications.

Pinout & Package

74LCX00YMTR is housed in a 14-pin SOIC (SO-14) package with standard 1.27 mm pitch, 8.55–8.75 mm body length, and ECOPACK® RoHS-compliant finish.

Pin/Terminal	Circuit Role	Design Meaning
1, 4, 9, 12 (1A–4A)	NAND Gate Input A	5 V tolerant logic inputs accepting 0–5.5 V signals; internally clamped to VCC/GND.
2, 5, 10, 13 (1B–4B)	NAND Gate Input B	Identical electrical behavior to A inputs; supports dual-input logic evaluation per gate.
3, 6, 8, 11 (1Y–4Y)	NAND Gate Output	Push-pull CMOS outputs with symmetrical sourcing/sinking; compatible with LVTTL/LVCMOS loads.
7	GND	Reference ground for all internal circuitry and I/O; requires low-impedance PCB return path.
14	VCC	Primary power supply pin (2.0–3.6 V); decoupling capacitor (100 nF) required within 5 mm.

Key Features

Feature	Design Value
5 V tolerant inputs	Enables seamless interface between 3.3 V logic and 5 V peripherals without external resistors or translators.
Power-down protection	Prevents back-driving and current leakage when VCC = 0 V, supporting hot-swap and partial-power-down modes.
Symmetrical output drive	Guarantees matched tPLH/tPHL (≤10% difference), reducing jitter in clock distribution and data strobing.
AEC-Q100 qualification	Validated for automotive Grade 3 operation (−40 °C to +85 °C) with advanced screening per AEC-Q001/Q002.
Low dynamic power	CPD = 35 pF enables <1 mW per gate at 10 MHz - suitable for battery-backed and thermally constrained modules.

Applications

Automotive Body Control Module

Industrial PLC Digital Input Card

Use Scenario: Signal conditioning of 5 V sensor switch inputs (e.g., door latch, seatbelt buckle) before feeding 3.3 V microcontroller GPIOs.

IC Role / Device Role / Timing Role: Level-translating NAND gate performing active-low debouncing and noise filtering via RC-NAND configuration.

Use Value: Eliminates need for discrete level shifters and reduces BOM count by 3 components per channel while maintaining AEC-Q100 compliance.

Use Scenario: Isolating and inverting field-side 24 V digital inputs through optocoupler outputs into 3.3 V FPGA control logic.

IC Role / Device Role / Timing Role: Logic buffer and polarity inverter ensuring clean, fast, and glitch-free signal edge delivery to FPGA registers.

Use Value: Delivers 4.3 ns propagation delay and ≤1 ns skew across four channels - critical for synchronized multi-channel sampling at 20+ kHz.

Embedded Computer Power Sequencing

Consumer Audio System Mute Control

Use Scenario: Generating precise enable/disable sequences for multiple 3.3 V/1.8 V power rails during system boot and shutdown.

IC Role / Device Role / Timing Role: Combinational logic element implementing AND/NAND-based dependency trees for rail activation order.

Use Value: Supports 24 mA drive strength to directly control multiple PMIC EN pins without buffering, reducing layout area and routing complexity.

Use Scenario: Implementing hardware mute logic that activates only when both audio source select and amplifier enable signals are asserted.

IC Role / Device Role / Timing Role: Dual-input NAND gate acting as a synchronous mute gate with zero added latency in analog signal path control.

Use Value: Achieves <5 ns total propagation uncertainty - prevents audible click/pop artifacts during mute/unmute transitions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad NAND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC00APWR	Non-automotive grade; 1.65–3.6 V VCC range; 5 V tolerant inputs; 3.7 ns tPD (typ.) at 3.3 V.	Lacks AEC-Q100 qualification and extended temperature validation; not approved for automotive production.	Select for cost-sensitive industrial or consumer designs where −40 °C to +85 °C operation is sufficient but automotive qualification is unnecessary.
74LVX00M	Lower drive (±12 mA at 3 V); wider VCC range (2.7–3.6 V); no AEC-Q100 qualification; same SO-14 footprint.	Insufficient output current for PCI bus or multi-load driving; limited thermal margin in high-ambient environments.	Choose only for ultra-low-power applications where 12 mA drive suffices and automotive reliability is not required.

Compared with SN74LVC00APWR and 74LVX00M, the 74LCX00YMTR uniquely combines AEC-Q100 Grade 3 qualification, 24 mA drive, and 5 V input tolerance in SO-14 - making it the only drop-in solution for automotive 3.3 V logic interface where functional safety and long-term supply continuity are mandated.

FAQ

Is 74LCX00YMTR pin-compatible with standard 74LS00 or 74HC00?

Yes - it is pin- and function-compatible with the 74-series 00 family, including 74LS00 and 74HC00, occupying the same SO-14 footprint and implementing identical truth tables. However, its 5 V tolerant inputs and 2.0–3.6 V supply range differ from 74LS00 (4.75–5.25 V) and 74HC00 (2–6 V), requiring appropriate VCC biasing.

Can 74LCX00YMTR operate reliably at 2.0 V supply?

Yes - the device is fully specified down to 2.0 V VCC, with guaranteed VIH = 2.0 V and VIL = 0.8 V over −40 °C to +85 °C. Propagation delay increases to 5.1 ns (max) at 2.7 V, and DC output drive remains ≥12 mA, supporting low-voltage battery-powered subsystems.

What is the significance of "YMTR" in the part number?

The "YMTR" suffix denotes automotive-grade qualification: "Y" indicates AEC-Q100 Grade 3 compliance and enhanced screening per AEC-Q001/Q002, while "MTR" specifies SO-14 packaging in tape-and-reel format (1000 units/reel), optimized for SMT assembly in automotive production lines.

Does 74LCX00YMTR require external pull-up or pull-down resistors on unused inputs?

No - unused inputs may be tied directly to VCC or GND. The device includes internal power-down protection and input clamping diodes; floating inputs are not permitted due to potential increased ICC and undefined logic states, but no external resistors are needed for termination.
