Product details

Overview

74LVX02M from onsemi is a low-voltage quad 2-input NOR gate IC designed for level translation between 5 V and 3.3 V systems, featuring ±25 mA output drive, 3.3 V supply operation (2.0–3.6 V), −40 °C to +85 °C industrial temperature range, and TSSOP-14 WB package with Pb-free, RoHS-compliant construction. It serves as a logic interface in mixed-voltage digital subsystems.

For engineers reviewing the 74LVX02M datasheet, pinout, applications, or equivalent options, key selection criteria include input voltage tolerance up to 6.5 V, guaranteed simultaneous switching noise performance, dynamic threshold compliance at 3.3 V, and compatibility with 5 V-tolerant I/O in 3.3 V logic domains.

Technical Context

The 74LVX02M implements four independent 2-input NOR gates with TTL-compatible input thresholds and CMOS-compatible output swing. Its inputs tolerate 0–5.5 V regardless of VCC (2.0–3.6 V), enabling robust 5 V → 3.3 V signal translation without external biasing.

Propagation delay is specified down to 4.5 ns (typ) at 3.3 V with 15 pF load; output-to-output skew is ≤1.5 ns across all gates. The device guarantees dynamic noise immunity via characterized VOLP/VOLV (±0.5 V) and VIHD/VILD (2.0 V/0.8 V) under 50 pF capacitive loading.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	2.0 V to 3.6 V - Enables direct integration into 3.3 V power rails with margin for supply variation.
Input Voltage Tolerance	−0.5 V to +6.5 V - Supports interfacing with legacy 5 V logic without level shifters.
Output Drive	±25 mA - Sufficient to drive multiple LVTTL or LVCMOS loads at full speed.
Propagation Delay	4.5 ns (typ) at 3.3 V, CL = 15 pF - Meets timing requirements for sub-100 MHz synchronous logic.
Operating Temperature	−40 °C to +85 °C - Qualified for industrial-grade embedded control and communications equipment.
Quiescent ICC	20 μA max at 3.6 V - Ensures ultra-low static power in battery-backed or always-on logic circuits.
Input Capacitance	10 pF max - Minimizes loading on upstream drivers and preserves signal integrity at high frequencies.

Pinout & Package

TSSOP-14 WB (Case 948G), 4.9 mm × 4.4 mm body, 0.65 mm pitch, 1.2 mm max height, Pb-free, halogen-free, RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 8, 9, 11, 12	A0/B0–A3/B3 Inputs	Four independent NOR gate inputs; each pair (An, Bn) feeds one gate; 5 V tolerant.
3, 6, 10, 13	O0–O3 Outputs	Active-low NOR outputs; rail-to-rail swing referenced to VCC/GND; ±25 mA sink/source.
7	GND	Digital ground reference for all logic and I/O; must be low-impedance connection.
14	VCC	Primary supply for core logic and output buffers; decoupling capacitor required near pin.

Key Features

Feature	Design Value
5 V-tolerant inputs	Enables direct connection to 5 V microcontrollers or FPGAs while operating from 3.3 V supply.
Guaranteed simultaneous switching noise immunity	Validated VOLP/VOLV limits ensure stable outputs during multi-gate switching in dense PCB layouts.
Low dynamic threshold variation	VIHD ≥ 2.0 V and VILD ≤ 0.8 V at 3.3 V guarantee reliable logic recognition under fast edge rates.
Pb-free, halogen-free, RoHS-compliant packaging	Meets global environmental compliance mandates without compromising thermal or mechanical reliability.
Low power dissipation	CPD = 15 pF enables predictable dynamic current calculation: ICC(opr.) = (CPD × VCC × fIN + ICC)/4 per gate.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC02APW	Lower VCC min (1.65 V), higher max output drive (±24 mA), identical TSSOP-14 package but non-5 V tolerant inputs (max VI = VCC + 0.5 V).	Requires external level shifting when interfacing 5 V sources; better suited for pure 1.8–3.3 V systems.	Select when operating below 2.0 V or when 5 V tolerance is unnecessary and lower ICC is critical.
74LCX02MTCX	Same 5 V-tolerant inputs and TSSOP-14 package, but higher ICC (50 μA max), wider VCC range (2.0–3.6 V), and slightly slower propagation (6.6 ns typ at 3.3 V/15 pF).	Compatible drop-in replacement where tighter noise specs or lower quiescent current are not required.	Choose when cost sensitivity outweighs need for lowest dynamic noise or tightest skew.

Compared with SN74LVC02APW and 74LCX02MTCX, the 74LVX02M uniquely balances 5 V input tolerance, sub-5 ns typical propagation, and <20 μA max ICC - making it optimal for mixed-voltage industrial interfaces demanding both robustness and speed.

FAQ

What is the maximum input voltage the 74LVX02M can tolerate?

The 74LVX02M supports DC input voltages from −0.5 V to +6.5 V, independent of VCC. This allows direct connection to 5 V logic families without external level-shifting circuitry. The specification is validated across the full operating temperature range (−40 °C to +85 °C) and applies to all input pins (A0–B3) of the 74LVX02M.

Does the 74LVX02M require pull-up or pull-down resistors on unused inputs?

Yes - per the datasheet's Recommended Operating Conditions (Note 1), all unused inputs of the 74LVX02M must be terminated either HIGH or LOW; floating inputs are prohibited. This prevents increased ICC, erratic output behavior, and potential damage due to undefined internal node states in the 74LVX02M.

What is the typical propagation delay of the 74LVX02M at 3.3 V?

The typical propagation delay (tPLH/tPHL) of the 74LVX02M is 4.5 ns at VCC = 3.3 V ±0.3 V with a 15 pF load and TA = 25 °C. Under worst-case conditions (TA = −40 °C to +85 °C, CL = 50 pF), the maximum delay is 11.5 ns - a value guaranteed across all four NOR gates in the 74LVX02M.

Is the 74LVX02M pin-compatible with other 74-series NOR gate packages?

The 74LVX02M uses the standard 14-pin TSSOP-14 WB footprint (Case 948G) with identical pinout to industry-standard quad 2-input NOR gates like the 74HC02 and 74LVC02. However, electrical compatibility depends on voltage tolerances and drive strength - the 74LVX02M's 5 V-tolerant inputs distinguish it from non-tolerant variants.

What does the "M" suffix in 74LVX02M indicate?

The "M" in 74LVX02M denotes the TSSOP-14 WB package variant per onsemi's ordering nomenclature. It corresponds to the orderable part number 74LVX02MTCX, where "TCX" specifies tape-and-reel packaging (2500 units). The marking "LVX 02" appears on the top surface of the 74LVX02M device.
