Product details

Overview

74VCX00MX from ON Semiconductor is a low-voltage quad 2-input NAND gate IC designed for logic-level translation and signal conditioning in mixed-supply systems. It operates from 1.2V to 3.6V V_CC, supports 3.6V-tolerant inputs/outputs, delivers ≤2.8ns propagation delay at 3.3V, and provides ±24mA drive strength at 3.0V - enabling use in battery-powered portable interfaces and voltage-scalable digital control circuits.

For engineers reviewing the 74VCX00MX datasheet, pinout, applications, or equivalent options, key selection considerations include its power-off high-impedance I/O behavior, JEDEC MO-241 DQFN-14 package compatibility, static drive capability across multiple V_CC rails, and compliance with JEDEC J-STD-020B lead-free standards.

Technical Context

The 74VCX00MX implements four independent 2-input NAND gates using advanced CMOS process technology optimized for speed-power trade-offs in sub-3.6V domains. Its input structure enables safe interfacing with higher-voltage (up to 3.6V) logic families while powered from as low as 1.2V, and its output stage maintains rail-to-rail swing and defined drive strength across V_CC = 1.2V–3.6V.

It features power-off high-impedance inputs and outputs - critical for hot-swap and partial-power-down system architectures - and meets JEDEC 78 latch-up immunity requirements (>250mA) and ESD robustness per HBM >2000V and MM >250V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.2V to 3.6V - supports single-supply operation across ultra-low-voltage microcontrollers, FPGAs, and mixed-voltage I/O domains.
Propagation Delay (t_PD)	≤2.8ns max at V_CC = 3.3V, CL = 30pF - enables timing-critical glue logic in high-speed digital subsystems.
I/O Voltage Tolerance	3.6V tolerant inputs and outputs - allows direct connection to 3.3V or 2.5V logic without level shifters.
Output Drive (I_OH/I_OL)	±24mA at V_CC = 3.0V - sufficient to drive multiple standard CMOS loads or small capacitive buses.
Power-Off High-Z	Inputs and outputs enter high-impedance state when V_CC = 0V - prevents back-driving and signal contention during power sequencing.
Operating Temperature	–40°C to +85°C - qualified for industrial-grade embedded control and communications equipment.

Pinout & Package

74VCX00MX is packaged in a 14-terminal depopulated quad very-thin flat no-lead (DQFN) per JEDEC MO-241, 2.5 mm × 3.0 mm footprint, with exposed die attach pad (DAP) for thermal enhancement. Pin assignments follow standard 74-series logic layout with dual-in-line functional grouping.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 8, 9, 11, 12	Gate Inputs (A1/B1, A2/B2, A3/B3, A4/B4)	Four independent NAND gate input pairs - each pair accepts 3.6V-tolerant logic signals regardless of V_CC.
3, 6, 10, 13	Gate Outputs (Y1–Y4)	CMOS-compatible outputs with rail-to-rail swing and ±24mA drive at 3.0V - support fan-out to ≥10 LVTTL loads.
7	GND	Ground reference for all logic and power domains - must be low-inductance connected to system ground plane.
14	V_CC	Primary supply input - powers internal logic and defines output voltage swing; supports 1.2V–3.6V range.
DAP (Bottom Center)	Die Attach Pad	Thermally conductive but electrically isolated copper pad - requires PCB thermal via connection for optimal junction temperature control.

Key Features

Feature	Design Value
Wide V_CC operating range	1.2V to 3.6V enables interoperability between legacy 3.3V systems and emerging ultra-low-power 1.2V SoCs.
3.6V-tolerant I/O	Eliminates external level translators when interfacing with 3.3V or 2.5V peripherals in mixed-voltage designs.
Power-off high-impedance I/O	Prevents current leakage and bus contention during power-down or hot-plug events in modular systems.
Low dynamic power dissipation	CPD = 20pF typical - reduces switching current and heat generation in high-frequency toggle applications.
JEDEC-compliant DQFN packaging	MO-241 footprint ensures mechanical compatibility with automated SMT assembly and IPC-7351 land patterns.

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	Operates 1.65V–3.6V; 3.6V-tolerant I/O; t_PD ≤ 3.7ns @ 3.3V; SOIC/TSSOP only - no DQFN option.	Lacks power-off high-Z; not suitable for hot-swap or partial-power-down systems.	Select when board space permits SOIC/TSSOP and power sequencing is fully controlled.
74AUP00GW,115	Ultra-low-power variant: V_CC = 0.8V–3.6V; t_PD ≤ 6.2ns @ 3.3V; DQFN-14 package; lower drive (±4mA @ 3.0V).	Optimized for energy-constrained always-on sensors - insufficient drive for bus buffering or LED control.	Select when minimizing quiescent current (<1µA) is primary; avoid for load-driving roles.

Compared with SN74LVC00APWR and 74AUP00GW,115, the 74VCX00MX uniquely combines 1.2V operation, 3.6V I/O tolerance, power-off high-Z, and ±24mA drive in a DQFN-14 package - making it the only option supporting both ultra-low-voltage logic and robust peripheral interfacing in compact industrial designs.

Manufacturer

ON Semiconductor (formerly Fairchild Semiconductor) is a global supplier of energy-efficient semiconductor solutions for automotive, industrial, cloud computing, medical, and IoT applications.

The VCX logic family - including the 74VCX00MX - was engineered for voltage-scalable digital interfacing in mixed-supply systems, emphasizing I/O tolerance, low-voltage operation, and robustness in thermally constrained environments.

FAQ

Is the 74VCX00MX still in active production?

No - the 74VCX00MX is marked DISCONTINUED and NOT RECOMMENDED FOR NEW DESIGN per ON Semiconductor's official documentation. However, Aetrix Electronics maintains limited legacy inventory and supports existing production programs with traceable, date-code-controlled stock and lifecycle coordination services for the 74VCX00MX.

What package variants does the 74VCX00MX use?

The 74VCX00MX specifically uses the 14-terminal DQFN package per JEDEC MO-241 (2.5 mm × 3.0 mm), designated MLP14A in ON Semiconductor's ordering nomenclature. Unlike the SOIC (74VCX00M) or TSSOP (74VCX00MTC) variants, the 74VCX00MX has no leads and requires thermal pad soldering to the PCB.

Does the 74VCX00MX support true 1.2V logic operation?

Yes - the 74VCX00MX is fully specified down to V_CC = 1.2V, with guaranteed VOH/VOL, VIH/VIL thresholds, and ±100µA output drive at that rail. Input thresholds scale with V_CC (e.g., VIH = 0.65 × V_CC), ensuring noise margin preservation across the full 1.2V–3.6V range.

Can unused inputs on the 74VCX00MX be left floating?

No - per the datasheet's Recommended Operating Conditions, floating or unused inputs must be held HIGH or LOW using pull-up/pull-down resistors. Leaving inputs unconnected risks increased ICC, erratic switching, and potential latch-up due to intermediate voltage states on CMOS inputs.

What is the function of the DAP (Die Attach Pad) on the 74VCX00MX?

The DAP is an exposed copper thermal pad on the underside of the DQFN package. It is electrically isolated but thermally conductive - intended to be soldered to a PCB thermal pad with vias to internal ground or power planes. Proper DAP connection reduces junction-to-board thermal resistance by up to 30%, critical for sustained operation at 85°C ambient.
