Product details
Overview
MC74LCXU04DTG 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 TTL/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 MC74LCXU04DTG datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options - all grounded in onsemi's official Rev. 13 datasheet (April 2026).
Technical Context
The MC74LCXU04DTG implements six independent unbuffered inverter stages 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.
Each inverter exhibits matched propagation delays (tPLH/tPHL ≤ 3.3 ns at VCC = 4.5–5.5 V) and output skew ≤ 1.0 ns (at VCC = 3.0–3.6 V), enabling precise timing alignment across multiple inverted signals in clock distribution or bus control paths.
Key Specifications

| Input Voltage Tolerance | −0.5 V to +6.5 V - allows direct connection to 5 V TTL outputs without external level shifters |
| Propagation Delay (max) | 3.3 ns at VCC = 4.5–5.5 V - supports >100 MHz toggle rates in high-speed digital control loops |
| Quiescent Supply Current | 10 µA - reduces standby power in always-on sensor interface or IoT edge node applications |
| Output Drive Strength | ±24 mA - sufficient to drive 50 pF loads with <4.6 ns delay at 1.65–1.95 V, ensuring robust fanout |
| ESD Withstand (HBM) | >4000 V - exceeds JEDEC JESD22-A114-A requirements for handling in automated assembly |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A0 (Input) | Inverter stage 0 input - high-impedance TTL-compatible node accepting 0–5.5 V logic levels |
| 2 | O0 (Output) | Inverter stage 0 output - CMOS rail-to-rail output sourcing/sinking up to ±24 mA |
| 3 | A1 (Input) | Inverter stage 1 input - electrically identical to A0; no internal coupling between stages |
| 4 | O1 (Output) | Inverter stage 1 output - matched delay and skew relative to O0 per AC specs |

| 8 | O3 (Output) | Inverter stage 3 output - shares same VCC/GND pins; no isolation between output stages |
| 9 | A3 (Input) | Inverter stage 3 input - 5 V-tolerant; VI leakage ≤ ±5 µA at 3.6 V ensures low crosstalk |
| 10 | O4 (Output) | Inverter stage 4 output - dynamic LOW peak voltage ≤ 0.8 V (VCC = 3.3 V) limits ground bounce |
| 11 | A4 (Input) | Inverter stage 4 input - input capacitance 7 pF enables fast edge response with minimal loading |
| 12 | O5 (Output) | Inverter stage 5 output - output-to-output skew ≤ 1.0 ns ensures synchronous multi-bit inversion |
| 13 | A5 (Input) | Inverter stage 5 input - unused inputs must be tied to GND or VCC to prevent floating-state oscillation |
| 14 | VCC | Positive supply - powers all six inverters; ICC increase ≤ 500 µA per active input above VCC − 0.6 V |

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 - requires external clamping for 5 V interface | Restricted to 3.3 V-only systems; unsuitable for mixed-voltage designs with 5 V peripherals | Select when operating exclusively at ≤3.6 V and cost-per-unit is prioritized over interface flexibility |
| 74AHC04PW,118 | Wider VCC range (2–5.5 V), but VI max = VCC + 0.5 V - not 5 V-tolerant at VCC < 4.5 V | Cannot safely accept 5 V inputs below 4.5 V supply; requires careful voltage-domain partitioning | Choose for higher drive strength (±8 mA @ 2 V) where 5 V input compatibility is unnecessary |
Compared with SN74LVC04APWR and 74AHC04PW,118, the MC74LCXU04DTG uniquely combines true 5 V input tolerance across its entire 1.65–5.5 V supply range, sub-4 ns propagation delay at 1.65 V, and 10 µA quiescent current - making it the only option for low-voltage, mixed-signal, and automotive-grade hex inversion without external components.

FAQ
What is the maximum input voltage the MC74LCXU04DTG can safely accept?
The MC74LCXU04DTG supports DC input voltages from −0.5 V to +6.5 V regardless of VCC level, enabling direct connection to 5 V TTL outputs even when powered from 1.65 V. This 5 V-tolerant capability is explicitly guaranteed in the Absolute Maximum Ratings table and confirmed by VI = 5.5 V operation in Recommended Operating Conditions.
Does the MC74LCXU04DTG require external pull-up or pull-down resistors on unused inputs?
Yes - per datasheet Section 3 (Recommended Operating Conditions), all unused inputs of the MC74LCXU04DTG must be tied to either GND or VCC to prevent floating states that could cause excessive supply current, oscillation, or increased EMI. The device does not include internal termination resistors.
What is the typical propagation delay of the MC74LCXU04DTG at 3.3 V supply?
At VCC = 3.0–3.6 V and TA = −40 °C to +85 °C, the MC74LCXU04DTG 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 with CL = 50 pF and RL = 500 Ω.
Is the MC74LCXU04DTG compatible with both LVTTL and LVCMOS logic families?
Yes - the MC74LCXU04DTG is explicitly characterized as both LVTTL and LVCMOS compatible in its Features section and meets VIH/VIL thresholds for both standards across its full 1.65–5.5 V VCC range, supporting interoperability with FPGAs, microcontrollers, and ASICs using either interface.
What package type does the MC74LCXU04DTG use, and is it RoHS-compliant?
The MC74LCXU04DTG uses a 14-lead TSSOP package (Case 948G) with 0.65 mm pitch and is Pb-free, halogen-free/BFR-free, and RoHS-compliant per onsemi's documentation. Its moisture sensitivity level is rated at Level 1, allowing unlimited floor life under standard handling conditions.
