Product details

Overview

74LVX02MTR from STMicroelectronics is a low-voltage CMOS quad 2-input NOR gate with 5V-tolerant inputs, operating from 2V to 3.6V supply, delivering 4.5ns typical propagation delay at 3.3V, 4mA output drive, and 2µA max quiescent current - used in level-shifting logic interfaces between 5V and 3.3V systems.

For engineers reviewing the 74LVX02MTR datasheet, 74LVX02MTR pinout, 74LVX02MTR application, or 74LVX02MTR equivalent, key selection criteria include 5V input tolerance, symmetrical 4mA I_OH/I_OL, sub-5ns speed at 3.3V, ESD immunity (2kV), and SO-14 package compatibility with legacy 74-series footprints.

Technical Context

The device implements four independent NOR gates using sub-micron C2MOS technology with buffered outputs for high noise immunity. Each gate features identical input thresholds (V_IL = 0.8V, V_IH = 2.0V at V_CC = 3V) and rail-to-rail 5V-tolerant inputs independent of supply voltage.

Dynamic performance is characterized by balanced t_PLH ≅ t_PHL, low quiet-output noise (V_OLP = 0.3V typ.), and skew <1.0ns across outputs under 50pF load - enabling reliable timing in synchronous logic translation and fanout distribution.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2V to 3.6V - supports battery-powered 3.3V systems with 1.2V data retention
t_PD (typ)	4.5ns at V_CC = 3.3V, CL = 15pF - enables high-speed logic interfacing below 220MHz toggle rate
I_OH/I_OL	±4mA min - drives standard TTL loads and multiple CMOS inputs without buffering
V_IH/V_IL	2.0V/0.8V at V_CC = 3.0V - ensures robust noise margin (>0.7V) in noisy 3.3V environments
Input Tolerance	0–7V independent of V_CC - allows direct connection to 5V signals without external resistors
I_CC (max)	2µA at T_A = 25°C - enables ultra-low-power operation in always-on control logic

Pinout & Package

74LVX02MTR is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package per JEDEC MS-012, with gull-wing leads, 1.27mm pitch, and tape-and-reel packaging (MTR suffix).

Pin/Terminal	Circuit Role	Design Meaning
1, 4, 10, 13	1Y, 2Y, 3Y, 4Y	Active-low NOR gate outputs - each capable of sourcing/sinking 4mA with rail-aligned VOH/VOL
2, 5, 8, 11	1A, 2A, 3A, 4A	First input per gate - 5V tolerant, no clamping required when driven from 5V sources
3, 6, 9, 12	1B, 2B, 3B, 4B	Second input per gate - identical electrical specs to A inputs, enabling symmetric dual-input logic
7	GND	Ground reference - shared return for all four gates; decoupling capacitor placement critical for noise suppression
14	V_CC	Positive supply - must be stabilized within 2V–3.6V; power-down protection prevents backfeed during V_CC off-state

Key Features

Feature	Design Value
5V-tolerant inputs	Accepts 0–7V input voltages regardless of V_CC state - eliminates level-shifters in mixed-voltage board designs
Symmetrical output drive	\|I_OH\| = \|I_OL\| ≥ 4mA - ensures matched rise/fall times and reduces signal distortion in clocked paths
Low dynamic noise	V_OLP = 0.3V (typ) at V_CC = 3.3V - minimizes ground bounce and crosstalk in dense PCB layouts
ESD protection	2kV HBM on all pins - meets industrial IEC 61000-4-2 Level 2 requirements without external TVS diodes

Applications

Industrial PLC I/O Expansion

Portable Medical Sensor Interface

Use Scenario: Isolating and conditioning digital status signals from 5V field sensors into a 3.3V microcontroller-based logic controller.

IC Role / Device Role / Timing Role: Level-translating NOR gate performing active-low enable logic and signal inversion prior to optocoupler input.

Use Value: Eliminates discrete resistor-divider networks while maintaining noise margin >0.7V and supporting 220MHz maximum toggle rate.

Use Scenario: Debouncing mechanical switches and combining alarm triggers from multiple low-power biosensors in battery-operated diagnostic devices.

IC Role / Device Role / Timing Role: Glue logic element implementing reset arbitration and fault-condition OR-ing with sub-5ns decision latency.

Use Value: Draws only 2µA quiescent current and retains valid logic states down to 1.2V supply - extending battery life in sleep-mode operation.

Automotive Body Control Module

IoT Edge Node Power Sequencing

Use Scenario: Interfacing legacy 5V CAN transceiver status lines with a 3.3V automotive MCU's GPIO interrupt inputs.

IC Role / Device Role / Timing Role: Voltage-adapting combinatorial logic block ensuring glitch-free wake-up signal generation under load dump conditions.

Use Value: Withstands 7V transient input excursions and maintains functional integrity across –40°C to +125°C ambient range.

Use Value: Balanced t_PLH/t_PHL ensures deterministic 10ns timing window between enable edges - preventing rail collapse during startup.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad NOR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC02APWR	Lower V_CC min (1.65V), higher speed (3.5ns typ), but only 5.5V input tolerant	Preferred for 1.8V–3.3V-only systems requiring faster switching; not suitable for direct 5V input interfacing	Select when system operates strictly ≤3.3V and needs tighter timing margins
74AHC02PW,118	Wider V_CC range (2–5.5V), higher drive (8mA), but no 5V-tolerant inputs relative to V_CC	Requires external clamping for 5V inputs; better for single-supply 5V or mixed 3.3V/5V designs with protection circuitry	Choose when interfacing to 5V sources is handled externally and higher output current is needed

Compared with SN74LVC02APWR and 74AHC02PW,118, the 74LVX02MTR uniquely combines true 5V input tolerance with sub-5ns speed and ultra-low 2µA standby current - making it optimal for cost-sensitive, battery-powered 3.3V systems interfacing legacy 5V peripherals without added components.

FAQ

Can 74LVX02MTR operate with a 1.8V supply?

No. The recommended operating V_CC range is 2.0V to 3.6V. At 1.8V, the device does not meet guaranteed DC specifications including V_IH, V_IL, and output drive strength. Data retention is supported down to 1.2V, but functional operation requires minimum 2.0V.

Is 74LVX02MTR pin-compatible with standard 74HC02?

Yes - it is pin- and function-compatible with the 74-series 02 logic family, including 74HC02 and 74LS02. All 14 pins match in assignment and physical layout, though electrical behavior (voltage levels, speed, drive) differs due to LVX's low-voltage CMOS process and 5V-tolerant inputs.

What is the maximum capacitive load this device can drive reliably?

The AC characteristics table specifies guaranteed timing up to 50pF load. While the device may function beyond that, propagation delay increases nonlinearly above 50pF, and output ringing or undershoot may occur. For loads >50pF, buffer stages or transmission line termination should be considered.

Does 74LVX02MTR require external pull-up or pull-down resistors on unused inputs?

No - unused inputs may be tied directly to V_CC or GND. The internal structure includes no floating-gate risk, and the 5V-tolerant input protection diodes ensure safe biasing. Leaving inputs unconnected is not recommended due to potential noise coupling and increased ICC.
