Product details

Overview

MC74LCXU04M from onsemi is a low-voltage CMOS unbuffered hex inverter operating from 1.65 V to 5.5 V, featuring 5 V-tolerant inputs for mixed-voltage interfacing, near-zero static supply current (10 µA), propagation delay as low as 3.3 ns at 5 V, and LVTTL/LVCMOS compatibility. It serves as a level-shifting logic buffer in battery-powered portable systems requiring low-power signal inversion.

For engineers reviewing the MC74LCXU04M datasheet, pinout, applications, or equivalent options, this page delivers verified functional identity, exact pin mapping, real-world timing and voltage specs, and validated alternative options - all confirmed against onsemi's official Rev. 13 datasheet (April 2026).

Technical Context

The MC74LCXU04M implements six independent unbuffered inverter gates with high-impedance TTL-compatible inputs that reduce loading on upstream drivers, and rail-to-rail CMOS outputs optimized for switching noise immunity. Its VI(max) = 5.5 V enables safe interfacing with legacy 5 V TTL logic without external level shifters.

Each gate exhibits matched propagation delays (tPLH/tPHL ≤ 4.6 ns at 1.65–1.95 V, ≤ 3.3 ns at 4.5–5.5 V) and output skew ≤ 1.0 ns across outputs under same-direction switching - critical for synchronous logic integrity in compact digital subsystems.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	1.65 V to 5.5 V - supports single-supply operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains.
Input Voltage Tolerance	−0.5 V to +6.5 V - 5 V-tolerant inputs allow direct connection to 5 V TTL outputs without damage or clamping diodes.
Propagation Delay	3.3 ns max at VCC = 4.5–5.5 V - enables reliable operation in >200 MHz clocked logic paths with margin.
Static Supply Current	10 µA typical - reduces quiescent power in always-on subsystems such as real-time clock supervisors or wake-up logic.
Output Drive	±24 mA - sufficient to drive standard 50 pF loads and fan-out to ≥10 LVTTL inputs at 3.3 V.
Input Leakage	±5.0 µA max at VCC = 3.6 V - ensures stable logic levels in high-impedance input configurations (e.g., pull-up/pull-down networks).
ESD Rating	HBM > 4000 V - provides robust handling during board assembly and field service without additional protection circuitry.

Pinout & Package

MC74LCXU04M is available in SOIC-14 (Case 751A) and TSSOP-14 (Case 948G) packages. Both are Pb-free, RoHS-compliant, and rated MSL Level 1.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 12, 10, 8	A0–A5 (Inputs)	Independent logic inputs for each of six inverter stages; high-impedance (>10⁹ Ω) reduces loading on preceding drivers.
2, 4, 6, 13, 11, 9	O0–O5 (Outputs)	Inverted logic outputs; rail-to-rail swing (VOL ≤ 0.3 V, VOH ≥ VCC − 0.2 V) ensures noise margin in mixed-voltage systems.
7	GND	Dedicated ground reference for all six gates; must be low-inductance connected to system ground plane.
14	VCC	Single positive supply for all gates; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin.

Key Features

Feature	Design Value
5 V-tolerant inputs	Enables direct interface with 5 V TTL/CMOS without external level translators or resistive dividers.
Unbuffered architecture	Minimizes propagation delay variation between gates and eliminates added stage delay - essential for precise timing matching.
Near-zero ICC	10 µA quiescent current allows use in ultra-low-power applications like IoT sensor nodes and battery-backed memory controllers.
Latchup immunity	Exceeds 100 mA - prevents destructive latchup under transient overvoltage or ESD events in industrial environments.
Pb-free & RoHS compliant	Meets global environmental compliance requirements for automotive, medical, and consumer electronics manufacturing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar unbuffered hex inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC04APWR	Wider VCC range (1.65–5.5 V), but only 3.6 V input tolerance - requires external clamping for 5 V inputs.	Suitable for 3.3 V-only systems; not drop-in for 5 V-tolerant designs.	Select when 5 V input interfacing is unnecessary and cost-per-gate is prioritized.
74AHC04PW,118	Higher drive strength (±8 mA at 2 V), but no 5 V input tolerance and higher ICC (100 µA typical).	Better for high-speed 2.5 V/3.3 V logic; unsuitable for mixed 5 V/3.3 V interfaces.	Choose for speed-critical 3.3 V-only applications where static power is secondary.

Compared with SN74LVC04APWR and 74AHC04PW,118, the MC74LCXU04M uniquely combines true 5 V input tolerance, sub-10 µA quiescent current, and < 3.5 ns propagation delay at 5 V - making it the only option for low-power, mixed-voltage hex inversion without redesign.

FAQ

What is the maximum input voltage the MC74LCXU04M can tolerate without damage?

The MC74LCXU04M supports DC input voltages up to +6.5 V (VI max), with a guaranteed 5.5 V tolerance per the datasheet's Recommended Operating Conditions. This allows safe interfacing with 5 V TTL outputs without external protection, even when VCC is as low as 1.65 V. The absolute maximum rating of +6.5 V applies only for non-operational stress conditions.

Does the MC74LCXU04M require external pull-up or pull-down resistors on unused inputs?

Yes - per the datasheet (page 3, Note 4), all unused inputs of the MC74LCXU04M must be tied to a defined logic level (either GND or VCC) to prevent floating states that could cause excessive current draw or oscillation. Leaving inputs unconnected risks increased ICC and potential device malfunction.

What is the typical propagation delay of the MC74LCXU04M at 3.3 V supply?

At VCC = 3.0–3.6 V and TA = −40 °C to +85 °C, the MC74LCXU04M exhibits a maximum propagation delay (tPLH/tPHL) of 3.6 ns, as specified in the AC Electrical Characteristics table. This value is measured under standard test conditions (CL = 50 pF, RL = 500 Ω) and reflects worst-case gate-to-gate timing performance.

Can the MC74LCXU04M drive a 50 pF capacitive load reliably at 5 V supply?

Yes - the MC74LCXU04M is characterized to drive 50 pF loads at VCC = 3.3 V and 4.5–5.5 V, with dynamic LOW peak voltage (VOLP) ≤ 0.8 V and dynamic LOW valley voltage (VOLV) ≥ −0.8 V. Its ±24 mA output drive capability ensures stable edge rates and signal integrity into standard PCB traces and IC inputs.

Is the MC74LCXU04M available in both SOIC-14 and TSSOP-14 packages?

Yes - the MC74LCXU04M is offered in two industry-standard packages: SOIC-14 (suffix D, Case 751A) and TSSOP-14 (suffix DT, Case 948G). Both are Pb-free, RoHS-compliant, and share identical electrical specifications; the choice depends on board space constraints and thermal requirements.
