Product details

Overview

74VCX08MX from ON Semiconductor is a low-voltage quad 2-input AND gate IC designed for logic-level translation and signal gating in mixed-voltage digital 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 direct interface between 1.2V/1.8V/2.5V/3.3V domains in portable and embedded control circuits.

For engineers reviewing the 74VCX08MX datasheet, pinout, applications, or equivalent options, this device serves as a voltage-flexible combinational logic gate where I/O tolerance, low static current (20µA), power-off high-impedance behavior, and DQFN packaging are critical selection criteria for space-constrained, multi-rail designs.

Technical Context

The 74VCX08MX implements four independent AND gates using advanced CMOS process technology optimized for speed-power trade-offs across 1.2V–3.6V supply ranges. Its input structure enables safe interfacing with higher-voltage signals up to 3.6V regardless of V_CC level, while output drivers maintain rail-to-rail swing and specified sink/source capability per V_CC tier.

Propagation delay varies predictably with supply voltage and load: 2.8ns max at 3.3V/30pF, 3.7ns at 2.5V/30pF, and 7.4ns at 1.8V/30pF. Output-to-output skew remains ≤0.75ns under identical switching conditions, supporting timing-critical parallel logic paths without added synchronization overhead.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.2V to 3.6V - Enables operation across ultra-low-voltage (1.2V) and standard 3.3V logic rails without level shifters.
I/O Voltage Tolerance	Up to 3.6V - Allows safe connection to 3.3V or 3.6V buses even when powered from 1.2V/1.8V supplies.
t_PD Max	2.8ns at V_CC = 3.3V, CL = 30pF - Supports >350MHz toggle rates in non-critical timing paths.
I_OH/I_OL	±24mA at V_CC = 3.0V - Drives multiple 74-series loads or small capacitive nets without buffering.
I_CC Quiescent	20µA max - Minimizes standby power in battery-operated systems with infrequent logic activity.
Power-Off Hi-Z	Inputs and outputs enter high-impedance state when V_CC = 0V - Prevents back-driving or contention on shared buses during power sequencing.
Operating Temp	–40°C to +85°C - Qualified for industrial ambient environments without derating.

Pinout & Package

74VCX08MX is packaged in a 14-terminal depopulated quad very-thin flat pack no leads (DQFN), JEDEC MO-241 compliant, measuring 2.5mm × 3.0mm with 0.5mm pitch. The package features an exposed die attach pad (DAP) for thermal enhancement and mechanical stability.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 8, 9, 11, 12	Input (A1/B1/A2/B2/A3/B3/A4/B4)	Eight logic inputs distributed across four AND gates; each tolerant to 3.6V regardless of V_CC.
3, 6, 10, 13	Output (Y1/Y2/Y3/Y4)	Four buffered AND outputs with rail-to-rail swing and ±24mA drive at 3.0V.
7	GND	Ground reference for all internal circuitry and I/O structures.
14	V_CC	Primary power supply pin; sets logic threshold and output drive strength.
DAP (Bottom Center)	Die Attach Pad	Thermally conductive, electrically isolated copper pad; must be soldered to PCB ground plane for optimal thermal performance.

Key Features

Feature	Design Value
Wide V_CC range (1.2V–3.6V)	Supports single-supply operation across multiple logic families without external regulators or translators.
3.6V-tolerant I/O	Eliminates need for discrete level-shifting components when interfacing with legacy 3.3V peripherals or sensors.
Power-off high-impedance I/O	Enables hot-plug compatibility and prevents bus contention during partial power-down sequences.
Latchup immunity >300mA	Ensures robustness against transient overvoltage events in noisy industrial or automotive subsystems.
ESD protection >2kV HBM	Reduces risk of handling damage during manual assembly or field maintenance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad 2-input AND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC08APWR	Operates 1.65V–3.6V; 3.6V-tolerant I/O; t_PD = 3.7ns max at 3.3V; SOIC/TSSOP only - no DQFN option.	Not suitable for 1.2V or 1.4V systems; lacks power-off high-Z; requires PCB redesign if replacing DQFN footprint.	Select when cost sensitivity outweighs ultra-low-voltage support and DQFN space constraints.
74AUP1G08GW,125	Single-gate variant; 0.8V–3.6V V_CC; t_PD = 6.1ns at 3.0V; available in XSON-6 (1.2×1.0mm); lower drive (±4mA).	Requires four devices to match quad functionality; smaller package but higher assembly complexity; insufficient drive for fanout >2.	Select for minimal footprint in low-fanout, ultra-low-power applications where gate count flexibility is preferred over integration.

Compared with SN74LVC08APWR and 74AUP1G08GW,125, the 74VCX08MX uniquely supports 1.2V operation, offers power-off high-impedance I/O, and integrates all four gates in a compact 2.5×3.0mm DQFN - making it the only choice for space-constrained, multi-voltage systems requiring guaranteed interoperability down to sub-1.4V logic rails.

FAQ

Is the 74VCX08MX still in active production?

No - the 74VCX08MX is marked DISCONTINUED and NOT RECOMMENDED FOR NEW DESIGN per official ON Semiconductor documentation. However, Aetrix Electronics maintains limited legacy inventory and supports continuity programs for existing production builds through traceable, verified sources and lifecycle coordination.

What does "3.6V-tolerant inputs and outputs" mean for the 74VCX08MX?

It means the 74VCX08MX inputs and outputs can safely accept or drive DC voltages up to 3.6V regardless of the V_CC supply level - even when V_CC is as low as 1.2V. This eliminates external level shifters when interfacing with 3.3V peripherals while operating from ultra-low-voltage rails.

Does the 74VCX08MX support power-off high-impedance mode?

Yes - when V_CC = 0V, both inputs and outputs of the 74VCX08MX automatically enter a high-impedance state. This prevents back-driving, bus contention, or leakage currents during power sequencing, hot-swap operations, or partial system shutdown - a key feature for robust system-level design.

What is the maximum propagation delay of the 74VCX08MX at 1.8V supply?

At V_CC = 1.8V ± 0.15V with C_L = 30pF and R_L = 500Ω, the 74VCX08MX has a maximum propagation delay (t_PHL/t_PLH) of 7.4ns. This value is confirmed in the AC Electrical Characteristics table and applies across the full operating temperature range (–40°C to +85°C).

Can the 74VCX08MX replace the 74VCX08M or 74VCX08MTC in a design?

Yes - the 74VCX08MX shares identical logic functionality, electrical specifications, and pinout with the 74VCX08M (SOIC) and 74VCX08MTC (TSSOP), differing only in package (DQFN) and tape-and-reel packaging suffix. No schematic or firmware changes are required, though PCB layout must accommodate the 2.5×3.0mm DQFN footprint and thermal pad.
