Product details
Overview
MC74LCX06MG from onsemi is a low-voltage CMOS hex inverter with six independent open-drain outputs, operating from 1.65 V to 5.5 V supply and featuring 5.0 V-tolerant inputs. It delivers 24 mA output sink capability at 3.0 V, supports wired-OR/AND logic functions, and exhibits near-zero static supply current (10 µA), making it suitable for level-shifting and bus interface applications in mixed-voltage systems.
For engineers reviewing the MC74LCX06MG datasheet, pinout, applications, or equivalent options, key selection considerations include its open-drain architecture, VIH/VIL voltage thresholds across VCC ranges, propagation delay down to 3.2 ns at 5 V, and compatibility with both LVTTL and LVCMOS logic families in multi-rail designs.
Technical Context
The MC74LCX06MG implements six identical inverting buffer stages, each with high-impedance TTL-compatible inputs and open-drain NMOS outputs. Its input structure tolerates up to 5.5 V regardless of VCC, enabling safe interfacing with legacy 5 V logic while powered from 1.65–3.3 V rails.
Each output supports active-low wired-OR functionality and external pull-up configuration without speed penalty. The device operates across –40 °C to +125 °C, with latchup immunity exceeding 100 mA and ESD robustness >2000 V HBM - critical for industrial and automotive subsystems requiring reliable signal conditioning.
Key Specifications

Pinout & Package
MC74LCX06MG is packaged in a 14-lead SOIC (Small Outline Integrated Circuit) per case 751A, with 1.27 mm pitch and Pb-free finish. Pin 1 is A0 (input), pin 2 is O0 (open-drain output), continuing alternately through A5/O5; pin 7 is GND and pin 14 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A5 | Inverter Input | High-impedance TTL-compatible inputs accepting 0–5.5 V signals regardless of VCC |
| O0–O5 | Open-Drain Output | NMOS drain-only outputs requiring external pull-up; enable wired-OR logic and level translation |
| VCC | Power Supply | Primary supply rail (1.65–5.5 V); powers internal logic but not output pull-up path |
| GND | Ground Reference | Common return for all inputs, outputs, and internal circuitry; must be low-impedance |
Key Features
| Feature | Design Value |
|---|---|
| 5 V–tolerant inputs | Enables seamless interfacing between 3.3 V microcontrollers and 5 V peripherals without external translators |
| Open-drain outputs | Supports bidirectional bus protocols (e.g., I²C) and active-low wired-OR logic sharing across multiple drivers |
| 24 mA sink capability | Drives standard LEDs directly or terminates 3.3 V/5 V buses with minimal external components |
| Sub-µA static current | Reduces standby power in portable and energy-sensitive applications such as sensor nodes and remote controls |
| Latchup immunity >100 mA | Ensures reliability under transient overvoltage or ESD events in harsh electrical environments |
Applications
| I²C Bus Level Shifting | LED Driver Interface |
|---|---|
Use Scenario: Translating signals between a 3.3 V microcontroller and 5 V I²C sensors or EEPROMs. IC Role / Device Role / Timing Role: Acts as bidirectional open-drain level shifter for SDA/SCL lines, preserving protocol timing integrity. Use Value: Eliminates need for dedicated level-shifter ICs; leverages inherent 5 V–tolerant inputs and open-drain outputs to maintain I²C compliance. | Use Scenario: Driving multiple indicator LEDs from a low-voltage MCU GPIO with shared anode configuration. IC Role / Device Role / Timing Role: Provides inverted, current-sinking output stage compatible with common-anode LED arrays. Use Value: Delivers 24 mA per channel at 3.0 V - sufficient for bright visual indicators without discrete transistors. |

IC Role / Device Role / Timing Role: Inverts and conditions individual reset signals before combining via open-drain wired-OR topology. Use Value: Ensures monotonic reset assertion/deassertion across mixed-voltage subsystems while meeting tight timing budgets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter with open-drain applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC06A | Same 1.65–5.5 V VCC range and open-drain outputs, but only 5 V–tolerant inputs (not 5.5 V); slightly higher ICC (max 10 µA vs. 10 µA typical) | Valid for 5 V logic interfacing but lacks margin for 5.5 V transients; lower ESD rating (2000 V HBM vs. >2000 V) | Preferred when cost sensitivity outweighs need for extended input voltage margin and enhanced ESD robustness |
| 74LVC06APW | TSSOP-14 package instead of SOIC-14; identical electrical specs including 5.5 V input tolerance and 24 mA sink capability | Same functional behavior but requires PCB layout change due to different footprint and thermal characteristics | Select when board space constraints favor TSSOP or when thermal performance under sustained load is prioritized |
Compared with SN74LVC06A and 74LVC06APW, the MC74LCX06MG offers superior input voltage margin (5.5 V vs. 5.0 V), identical sink strength, and higher latchup immunity - making it preferable for automotive and industrial applications where voltage transients and long-term reliability are critical.

FAQ
What is the maximum input voltage rating for MC74LCX06MG?
The MC74LCX06MG supports DC input voltages up to 5.5 V, independent of VCC level. This specification allows safe interfacing with 5 V logic sources even when the device is powered from as low as 1.65 V - a key advantage over standard LVC devices limited to 5.0 V input tolerance. This margin accommodates transient overshoot and ensures robust operation in noisy environments.
Does MC74LCX06MG require external pull-up resistors on its outputs?
Yes, MC74LCX06MG requires external pull-up resistors on all O0–O5 outputs because they are open-drain NMOS structures with no internal pull-up. The value depends on bus capacitance and rise time requirements - typical values range from 1 kΩ (for fast edges on low-capacitance lines) to 10 kΩ (for I²C-compliant buses). Without pull-ups, outputs remain floating in the high-impedance state.
Can MC74LCX06MG operate at 1.8 V supply voltage?
Yes, MC74LCX06MG is fully specified to operate at 1.8 V VCC, with guaranteed performance including propagation delay ≤6.5 ns and 24 mA sink capability at 3.0 V (derated at lower voltages). Its 1.65–5.5 V operating range makes it ideal for modern low-power systems using 1.8 V core logic while retaining compatibility with higher-voltage peripherals.
Is MC74LCX06MG pin-compatible with MC74LCX05?
No, MC74LCX06MG is not pin-compatible with MC74LCX05. While both belong to the LCX family and share functional compatibility (hex inverter vs. hex buffer), MC74LCX05 has non-inverting outputs and different pin assignments. The MC74LCX06MG uses alternating input/output pins (A0/O0, A1/O1, etc.), whereas MC74LCX05 follows a grouped input-then-output layout - requiring PCB redesign for substitution.
What is the thermal resistance (θJA) of MC74LCX06MG in SOIC-14 package?
The MC74LCX06MG in SOIC-14 package (case 751A) has a junction-to-ambient thermal resistance (θJA) of 116 °C/W under standard JEDEC test conditions (76 mm × 114 mm, 2-ounce copper, still air). This value assumes minimum pad spacing on FR4 and is used to estimate junction temperature rise under load - critical for reliability validation in thermally constrained applications.
