Product details
Overview
MC74VHC2G17MU3TCG from onsemi is a dual non-inverting Schmitt trigger buffer IC operating from 2.0 V to 5.5 V, featuring CMOS-level input thresholds, 4.0 ns typical propagation delay at 5 V, ±8 mA output drive, and overvoltage-tolerant I/O up to 5.5 V. It serves as a noise-immune signal conditioner in digital interface and level-shifting circuits.
For engineers reviewing the MC74VHC2G17MU3TCG datasheet, pinout, applications, or equivalent options, key selection criteria include Schmitt-trigger hysteresis (0.3–1.6 V), UDFN6 package footprint (1.0 × 1.0 mm), IOFF partial power-down support, and −55 °C to +125 °C industrial temperature range.
Technical Context
The MC74VHC2G17MU3TCG integrates two independent Schmitt-trigger buffers with hysteresis-VT+ = 2.20–3.85 V and VT− = 0.9–1.65 V at VCC = 3.0–5.5 V-enabling reliable noise rejection on slow or noisy input signals. Its CMOS input thresholds align with standard logic families across the full 2.0–5.5 V supply range.
It supports tri-state-compatible operation via IOFF circuitry that disables I/O leakage when VCC = 0 V, and delivers rail-to-rail output swing with VOH ≥ 2.34 V and VOL ≤ 0.52 V at 8 mA sink/source under worst-case conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports single-supply operation across 3.3 V and 5 V systems without level translation |
| tPD (Typ) | 4.0 ns at VCC = 5 V, CL = 15 pF - enables high-speed signal conditioning in timing-critical paths |
| VT+ / VT− | 2.20 V / 0.90 V min at VCC = 3.0 V - provides 1.3 V hysteresis for robust noise immunity on analog-like inputs |
| IOL / IOH | 8 mA sink / 4 mA source at VCC = 4.5 V - drives multiple 74VHC inputs or small capacitive loads directly |
| IOFF Leakage | <10 µA at VCC = 0 V - prevents back-powering and ensures safe partial power-down in mixed-voltage systems |
| Operating Temp | −55 °C to +125 °C - qualified for automotive under-hood, industrial control, and harsh-environment applications |
| Package | UDFN6 (1.0 × 1.0 mm, 0.35 mm pitch) - ultra-compact footprint for space-constrained PCB layouts |
Pinout & Package
MC74VHC2G17MU3TCG is housed in a 6-pin UDFN package (Case 517BX), 1.0 mm × 1.0 mm, 0.35 mm pitch, with wettable flank terminals for automated optical inspection. Pin 1 is marked by a rotated orientation (90° clockwise) in tape-and-reel packaging.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Y1) | Output 1 | Non-inverting buffered output of A1; rail-to-rail CMOS compatible |
| 2 (A2) | Input 2 | Schmitt-trigger input with hysteresis; tolerant to slow edges and noise |
| 3 (A1) | Input 1 | Schmitt-trigger input with identical threshold behavior to A2 |
| 4 (Y2) | Output 2 | Non-inverting buffered output of A2; electrically isolated from Y1 |
| 5 (GND) | Ground | Reference return for all internal circuitry and I/O; must be low-impedance |
| 6 (VCC) | Supply | Primary power rail; decoupling capacitor required within 2 mm for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| CMOS-level Schmitt thresholds | Enables direct interfacing with 3.3 V/5 V microcontrollers and sensors without external biasing |
| IOFF partial power-down | Prevents current backflow and system-level contention when VCC is off or ramping |
| Overvoltage-tolerant I/O | Accepts inputs up to 5.5 V regardless of VCC level-supports mixed-voltage domain bridging |
| Low quiescent ICC | ≤40 µA max at VCC = 5.5 V - suitable for always-on monitoring and battery-backed subsystems |
| Pb-free, RoHS-compliant | Meets global environmental compliance requirements including halogen-free/BFR-free construction |
Applications
| Industrial Sensor Interface | Microcontroller Input Conditioning |
|---|---|
Use Scenario: Analog sensor outputs (e.g., thermistor, potentiometer) feed into noisy industrial environments with EMI and long traces. IC Role / Device Role / Timing Role: Schmitt-trigger buffer cleans slow-rising/falling analog-derived logic signals before MCU sampling. Use Value: 1.3 V hysteresis at 3.0 V supply rejects >300 mV of superimposed noise, eliminating false triggers in PLC I/O modules. | Use Scenario: Pushbutton or mechanical switch inputs connected directly to GPIO pins of an ARM Cortex-M microcontroller. IC Role / Device Role / Timing Role: Debounces and sharpens switch transitions while providing voltage-level compatibility. Use Value: Eliminates need for external RC networks or firmware debouncing; 4.0 ns tPD preserves real-time response in safety-critical edge detection. |
| Legacy Bus Signal Restoration | Level Translation Between Voltage Domains |
Use Scenario: TTL or LSTTL signals degrade over long PCB traces or cables in legacy test equipment or instrumentation. IC Role / Device Role / Timing Role: Restores signal integrity and fan-out capability using Schmitt-trigger regeneration. Use Value: Drives up to 10 74VHC loads per output while rejecting ground bounce and crosstalk-induced glitches. | Use Scenario: Interfacing a 5 V legacy peripheral (e.g., UART transceiver) with a 3.3 V FPGA or SoC I/O bank. IC Role / Device Role / Timing Role: Acts as unidirectional level shifter with overvoltage-tolerant inputs and rail-aligned outputs. Use Value: Accepts 5 V inputs at VCC = 3.3 V and outputs clean 0–3.3 V logic-no external resistors or direction control needed. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G17DBVR | Lower VCC range (1.65–5.5 V); 3.5 ns tPD at 3.3 V; no IOFF | Lacks partial power-down protection; unsuitable for hot-swap or mixed-power domains | Select when cost and speed at 3.3 V are prioritized over robustness in power-gated systems |
| 74AUP2G17GW,125 | Ultra-low power (ICC < 1 µA); wider temp range (−40 to +125 °C); 12 ns tPD at 3.3 V | Slower propagation; optimized for battery-powered IoT nodes, not high-speed interfaces | Select when sub-µA static current dominates design constraints and timing margin allows >10 ns delay |
Compared with SN74LVC2G17DBVR and 74AUP2G17GW,125, the MC74VHC2G17MU3TCG uniquely combines industrial temperature rating, IOFF-enabled partial power-down, and 4.0 ns speed at 5 V-making it optimal for automotive body controllers and industrial PLCs requiring both noise immunity and system-level power management.

FAQ
What is the input hysteresis voltage of the MC74VHC2G17MU3TCG at 3.0 V supply?
The MC74VHC2G17MU3TCG exhibits a hysteresis voltage (VH) of 0.30 V minimum and 1.20 V maximum at VCC = 3.0 V, with typical values of 0.57 V at 25 °C. This hysteresis ensures reliable switching in the presence of noise or slow input transitions, and is confirmed in the DC Electrical Characteristics table for the MC74VHC2G17 variant on page 4 of the official datasheet.
Does the MC74VHC2G17MU3TCG support partial power-down functionality?
Yes, the MC74VHC2G17MU3TCG supports partial power-down via its IOFF feature: when VCC = 0 V, input and output leakage remains below 10 µA, preventing back-current flow and enabling safe operation in mixed-power-domain systems. This behavior is explicitly specified in the DC Electrical Characteristics table on page 4 of the datasheet.
What is the maximum operating temperature range for the MC74VHC2G17MU3TCG?
The MC74VHC2G17MU3TCG is rated for operation from −55 °C to +125 °C, as stated in the Recommended Operating Conditions table on page 3 of the datasheet. This extended range qualifies it for under-hood automotive, industrial motor control, and outdoor infrastructure applications where ambient temperatures exceed commercial-grade limits.
Can the MC74VHC2G17MU3TCG accept 5 V inputs while powered from a 3.3 V supply?
Yes-the MC74VHC2G17MU3TCG features overvoltage-tolerant inputs rated up to 5.5 V regardless of VCC level. When operated at VCC = 3.3 V, it safely accepts 5 V logic inputs without damage or clamping, making it ideal for level-shifting between legacy 5 V peripherals and modern 3.3 V controllers.
What package type and dimensions does the MC74VHC2G17MU3TCG use?
The MC74VHC2G17MU3TCG uses the UDFN6 package (Case 517BX): 1.0 mm × 1.0 mm body size, 0.35 mm lead pitch, and wettable flank terminals. Mechanical dimensions-including A (0.45–0.55 mm height), b (0.12–0.22 mm terminal width), and e (0.35 mm pitch)-are fully specified on page 7 of the datasheet.
