Product details
Overview
MC74LCXU04DTR2 from onsemi is a low-voltage CMOS unbuffered hex inverter operating from 1.65 V to 5.5 V, featuring 5 V-tolerant inputs, 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 logic-level translation and signal inversion component in mixed-voltage digital systems such as industrial controllers and portable instrumentation.
For engineers reviewing the MC74LCXU04DTR2 datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options for voltage-flexible inverter design.
Technical Context
The MC74LCXU04DTR2 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 input structure supports safe interfacing with 5 V TTL logic while powered from as low as 1.65 V.
All six inverters share a common VCC (Pin 14) and GND (Pin 7) supply pair, operate over −40 °C to +125 °C, and exhibit matched propagation delays (tPLH/tPHL ≤ 4.6 ns at 1.65–1.95 V) and output skew ≤1.0 ns across outputs under identical conditions.
Key Specifications

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 max VCC (3.6 V); no 5 V input tolerance; 3.3 ns delay at 3.3 V. | Restricted to 3.3 V-only systems; requires external clamping for 5 V inputs. | Select when cost and footprint are prioritized over 5 V interface capability. |
| 74LVCU04PW,118 | Same 5 V-tolerant inputs and 1.65–5.5 V range; slightly higher ICC (20 µA typ). | Functionally identical but sourced from Nexperia; pinout and timing match MC74LCXU04DTR2. | Preferred for dual-sourcing in high-volume industrial designs requiring second-source assurance. |
Compared with SN74LVC04APWR, MC74LCXU04DTR2 enables direct 5 V TTL interfacing without redesign; versus 74LVCU04PW,118, it offers lower quiescent current and tighter output skew-critical for timing-sensitive mixed-voltage systems.

FAQ
What is the maximum input voltage rating for MC74LCXU04DTR2?
The MC74LCXU04DTR2 supports DC input voltages from −0.5 V to +6.5 V, enabling safe interfacing with 5 V TTL outputs even when powered from 1.65 V to 3.3 V supplies. This 5 V-tolerant feature is explicitly specified in the Absolute Maximum Ratings table and confirmed across all operating conditions in the datasheet.
Does MC74LCXU04DTR2 require external pull-up resistors on unused inputs?
Yes, per the datasheet recommendation on page 3, unused inputs of the MC74LCXU04DTR2 must be tied to either GND or VCC to prevent floating states that could increase ICC and cause unpredictable switching. The device does not include internal pull-up or pull-down resistors.
What is the propagation delay variation between outputs of MC74LCXU04DTR2?
The MC74LCXU04DTR2 guarantees output-to-output skew (tOSHL/tOSLH) ≤1.0 ns for VCC = 3.0–3.6 V, measured across any two outputs switching in the same direction. This tight skew is critical for synchronous signal inversion in timing-critical applications like clock buffering and test equipment.
Can MC74LCXU04DTR2 operate reliably at 125 °C junction temperature?
Yes, the MC74LCXU04DTR2 is fully characterized and rated for continuous operation from −40 °C to +125 °C ambient temperature, with junction temperature limited to +150 °C. Its DC and AC specifications-including VIH/VIL thresholds and propagation delay-are guaranteed across this full range.
Is MC74LCXU04DTR2 pin-compatible with standard SOIC-14 versions of the same device?
No-MC74LCXU04DTR2 uses a TSSOP-14 package (Case 948G) with 0.65 mm pitch, while SOIC-14 versions (e.g., MC74LCXU04DR2G) use 1.27 mm pitch and larger footprint. Pin numbering and function mapping are identical, but PCB layout and soldering process differ significantly.
