Product details
Overview
MC74LCXU04DG 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 SOIC-14 packaging. It serves as a level-shifting logic buffer in battery-powered microcontroller I/O expansion and industrial sensor interface circuits.
For engineers reviewing the MC74LCXU04DG datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, SOIC-14 terminal mapping, real-world use cases, and two validated alternative parts with functional and application-level distinctions.
Technical Context
The MC74LCXU04DG implements six independent unbuffered inverter stages with high-impedance TTL-compatible inputs that reduce loading on upstream drivers, and LVTTL/LVCMOS-compatible outputs optimized for switching noise immunity. Its input voltage tolerance up to 5.5 V enables direct connection to legacy 5 V TTL logic without external level shifters.
Each inverter stage operates with rail-to-rail output swing, supports full 1.65–5.5 V VCC range, and maintains guaranteed VIH/VIL thresholds across temperature (−40 °C to +125 °C). Output drive capability is ±24 mA at 3.0–4.5 V, with dynamic switching characteristics characterized under 30–50 pF loads.

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 | Lower VCC min (1.65 V same), but only 3.6 V input tolerance - requires external clamping for 5 V inputs. | Best suited for pure 3.3 V or dual-supply 1.8 V/3.3 V systems where 5 V interfacing is absent. | Select when cost and footprint are prioritized over 5 V tolerance; verify input protection in mixed-voltage designs. |
| 74AHC04PW,118 | Wider VCC range (2–5.5 V), higher drive (±8 mA @ 2 V), but no 5 V input tolerance - VI max = VCC + 0.5 V. | Preferred in high-noise 5 V-only systems requiring faster propagation (2.5 ns typ) and stronger noise immunity. | Choose for 5 V-only applications needing tighter skew and lower dynamic power; avoid if interfacing with 5 V TTL. |
Compared with SN74LVC04APWR and 74AHC04PW,118, the MC74LCXU04DG uniquely combines 5 V input tolerance with sub-5 ns delay and 10 µA quiescent current - making it the only option among the three qualified for direct 5 V-to-1.8 V level translation without external components.

FAQ
What is the maximum input voltage rating for MC74LCXU04DG?
The MC74LCXU04DG supports DC input voltages up to 5.5 V, independent of VCC. This 5 V-tolerant feature allows direct connection to 5 V TTL outputs without risk of damage or latchup, even when VCC is as low as 1.65 V. The absolute maximum rating is specified in the datasheet's Maximum Ratings table and confirmed across temperature ranges.
Does MC74LCXU04DG require external pull-up or pull-down resistors on unused inputs?
Yes - per the datasheet's Recommended Operating Conditions section, all unused inputs of the MC74LCXU04DG must be tied to a valid logic level (either GND or VCC). Leaving inputs floating can cause increased ICC, oscillation, or excessive power dissipation due to undefined input states affecting internal CMOS structure.
What is the typical propagation delay of MC74LCXU04DG at 3.3 V supply?
At VCC = 3.3 V and TA = +25 °C, the typical propagation delay (tPLH/tPHL) of MC74LCXU04DG is 3.6 ns, with a maximum of 3.6 ns guaranteed across −40 °C to +85 °C per the AC Electrical Characteristics table. This value is measured under standard load conditions (RL = 500 Ω, CL = 50 pF).
Is MC74LCXU04DG compatible with both LVTTL and LVCMOS logic families?
Yes - the MC74LCXU04DG is explicitly specified as LVTTL and LVCMOS compatible in its datasheet features. Its VIH and VIL thresholds meet LVTTL requirements at 3.3 V (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and LVCMOS thresholds across 1.65–5.5 V VCC, enabling seamless integration into mixed-logic-system designs.
What package type is used for MC74LCXU04DG, and is it RoHS-compliant?
MC74LCXU04DG uses the SOIC-14 (Case 751A) package with Pb-free finish, confirmed in the Ordering Information table and Package Dimensions section. It is fully RoHS-compliant, halogen-free/BFR-free, and rated MSL Level 1 - meaning it can be stored indefinitely without dry-pack requirements prior to reflow soldering.
