Product details
Overview
M74HC05RM13TR from STMicroelectronics is a high-speed CMOS hex inverter with open-drain outputs, designed for level-shifting and wired-OR logic applications. It operates across 2V–6V supply, delivers 10ns typical propagation delay at 6V, supports ±20mA output current, and features 1µA max quiescent ICC at 25°C.
For engineers reviewing the M74HC05RM13TR datasheet, M74HC05RM13TR pinout, M74HC05RM13TR application, or M74HC05RM13TR equivalent, key selection criteria include open-drain drive capability, wide VCC range compatibility, noise immunity (28% VCC), and TSSOP-14 footprint suitability for space-constrained digital interface designs.
Technical Context
The M74HC05RM13TR implements six independent inverting buffers with open-drain outputs, requiring external pull-up resistors for logic-high assertion. Its C2MOS silicon gate process enables rail-to-rail input voltage tolerance (0 to VCC) and low dynamic power consumption.
All inputs include protection diodes against ESD and transient overvoltage; output stages are rated for 5.2mA sink current at 6V with VOL ≤ 0.4V, and support capacitive loads up to 50pF with controlled transition times (tTHL ≤ 19ns at 4.5V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2V to 6V - Enables direct interfacing with 3.3V and 5V logic families without level translators. |
| tPD (Typ.) | 10ns at VCC = 6V - Supports >30MHz toggle rates in clocked bus systems. |
| IO Sink | 5.2mA at VCC = 6V - Drives standard TTL loads and small-signal MOSFET gates directly. |
| VNIH/VNIL | 28% VCC min - Provides robust noise margin against coupled transients on shared PCB traces. |
| ICC (Max) | 1µA at TA = 25°C - Enables ultra-low-power standby in battery-backed control logic. |
| CIN / COUT | 5pF / 10pF - Minimizes loading on driving gates and reduces signal integrity risk in high-speed routing. |
Pinout & Package
TSSOP-14 package: 4.9 × 6.4 mm body, 0.65 mm pitch, exposed pad not present, JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (1A–6A) | Digital logic inputs accepting 0–VCC voltage; internally protected against ±20mA ESD current. |
| 2, 4, 6, 8, 10, 12 | Open-Drain Output (1Y–6Y) | Sink-only outputs requiring external pull-up; capable of 5.2mA @ 6V with VOL ≤ 0.4V. |
| 7 | GND | Reference ground for all I/O and internal circuitry; must be low-impedance connection. |
| 14 | VCC | Positive supply rail; decoupling capacitor (100nF) recommended within 5mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Open-drain outputs | Enable wired-OR bus architectures and mixed-voltage level shifting without direction control logic. |
| High noise immunity | 28% VCC input threshold hysteresis ensures reliable operation in electrically noisy industrial environments. |
| Wide supply range | 2V–6V operation allows single-supply use across 3.3V microcontrollers and legacy 5V peripheral interfaces. |
| Low ICC quiescent current | 1µA max at 25°C supports always-on monitoring circuits in energy-sensitive IoT edge nodes. |
Applications
| Industrial Control Bus | I²C Level Translation |
|---|---|
Use Scenario: Driving shared interrupt lines across multiple PLC modules with varying supply voltages. IC Role / Device Role / Timing Role: Open-drain inverter provides bidirectional signal conditioning and voltage-domain isolation on multi-drop control buses. Use Value: Eliminates need for discrete MOSFET translators; 6V tolerance prevents latch-up when interfacing 5V sensors to 3.3V controllers. | Use Scenario: Translating SDA/SCL signals between 3.3V microcontroller and 5V EEPROM in embedded systems. IC Role / Device Role / Timing Role: Six independent inverters allow dual-channel I²C translation plus auxiliary control line inversion. Use Value: Meets I²C timing requirements (tPD ≤ 10ns) while maintaining bus capacitance below 400pF limit via low COUT (10pF). |
| LED Matrix Row Driver | Reset Signal Conditioning |
Use Scenario: Sinking current from common-anode LED matrix rows driven by microcontroller GPIOs. IC Role / Device Role / Timing Role: Inverter stage converts active-high row select signals to active-low sinking outputs compatible with NPN/P-channel drivers. Use Value: 5.2mA sink capability per channel drives up to 8× 20mA LEDs simultaneously without external transistors. | Use Scenario: Debouncing and inverting manual reset button signals before feeding into FPGA or MCU reset pins. IC Role / Device Role / Timing Role: Provides Schmitt-trigger-like noise rejection via high VNIH/VNIL margins and clean signal inversion. Use Value: 1µA ICC enables permanent connection to battery-backed reset circuits without measurable drain impact. |
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 |
|---|---|---|---|
| SN74HC05DR | SOIC-14 package; identical AC/DC specs but higher COUT (12pF vs 10pF); same 2–6V VCC range. | Less suitable for high-density layouts where TSSOP-14 footprint is required. | Select when board space permits SOIC and legacy assembly infrastructure is in place. |
| 74LVC05PW | 3.3V-only operation (1.65–3.6V); lower VOL (0.1V @ 24mA); smaller TSSOP-14 body (4.4 × 3.0 mm). | Not usable in 5V systems; requires separate 3.3V rail if main system runs at 5V. | Prefer for new 3.3V-only designs prioritizing lowest possible VOL and board area. |
Compared with SN74HC05DR and 74LVC05PW, the M74HC05RM13TR uniquely balances 2–6V universal supply compatibility, TSSOP-14 miniaturization, and proven industrial temperature range (−55°C to +125°C), making it optimal for mixed-voltage retrofit and harsh-environment deployments.

FAQ
Can M74HC05RM13TR drive a 10kΩ pull-up resistor at 5V?
Yes. With VOL ≤ 0.4V at 5.2mA sink current and 6V max rating, the device fully satisfies I²C bus specifications using 10kΩ pull-ups at 5V. At 5V, typical sink current is ~4.5mA, yielding VOL ≈ 0.25V - well within 0.4V limit and ensuring valid logic-low recognition by 5V receivers.
Is the M74HC05RM13TR RoHS compliant and lead-free?
Yes. Per STMicroelectronics' official product change notice PCN 19-0127, M74HC05RM13TR is manufactured in full compliance with RoHS Directive 2011/65/EU and uses lead-free terminations with matte tin plating. The TSSOP-14 package meets JEDEC J-STD-020 moisture sensitivity level 1.
What is the maximum capacitive load the outputs can drive reliably?
The outputs are characterized up to 50pF (per AC specs), with tPLZ/tPZL degradation limited to 23ns max at 6V. For loads exceeding 50pF, rise time increases linearly with capacitance; design practice limits total node capacitance (trace + load + COUT) to ≤ 75pF to maintain <30ns transition integrity in 10MHz+ applications.
Does M74HC05RM13TR require external bypass capacitors?
Yes. A 100nF ceramic capacitor placed between VCC (pin 14) and GND (pin 7), with trace length ≤ 5mm, is mandatory to suppress switching noise and prevent supply rail collapse during simultaneous output transitions. Additional bulk capacitance (1–10µF) is recommended near the power entry point for multi-gate switching events.
