Product details
Overview
MC74VHC132MELG from onsemi is a quad 2-input NAND Schmitt trigger IC in SOIC-14 package, operating from 2.0 V to 5.5 V, with 4.9 ns typical propagation delay at 5.0 V, 28% VCC noise immunity, and TTL-compatible input thresholds for MC74VHCT variants. It functions as a noise-immune line receiver in digital interface conditioning circuits.
For engineers reviewing the MC74VHC132MELG datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, Schmitt-trigger hysteresis values, input/output voltage compatibility across 3.3 V/5.0 V domains, thermal resistance (116 °C/W), and real-world use cases in signal conditioning and level translation.
Technical Context
The MC74VHC132MELG implements four independent Schmitt-trigger NAND gates using silicon-gate CMOS technology, achieving bipolar-speed performance with CMOS power efficiency. Its three-stage internal architecture includes a buffer output stage that enhances noise immunity and stabilizes switching behavior.
Input hysteresis (VH = 0.3–1.6 V, depending on VCC) enables reliable operation with slow-rising/falling signals, while input structures tolerate up to 5.5 V - allowing safe interfacing between 3 V and 5 V systems without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND with Schmitt-trigger inputs for noise rejection and clean signal squaring |
| Propagation Delay | 4.9 ns typical at VCC = 5.0 V, CL = 15 pF - enables high-speed digital signal conditioning |
| Hysteresis Voltage (VH) | 0.30–0.50 V typical (VCC = 3.0–5.5 V) - ensures robust noise margin against EMI-induced glitches |
| Supply Range | 2.0 V to 5.5 V - supports mixed-voltage system integration including 3.3 V and 5.0 V rails |
| Input Voltage Tolerance | −0.5 V to +6.5 V - permits hot-plug and battery-backup-safe interfacing with overvoltage transients |
| Output Swing | Full-rail CMOS-level outputs (VOH ≥ 4.4 V, VOL ≤ 0.1 V at VCC = 4.5 V, IOL = 50 µA) - drives standard logic loads directly |

Pinout & Package
MC74VHC132MELG is housed in a Pb-free SOIC-14 (Case 751A) package measuring 8.75 mm × 3.90 mm × 1.75 mm, with 1.27 mm pitch, 116 °C/W junction-to-ambient thermal resistance, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 12, 13 | NAND Input (A1/B1/A2/B2/A3/B3/A4/B4) | Dual Schmitt-trigger inputs per gate - accept slow edges and reject noise below hysteresis threshold |
| 3, 6, 10, 11 | NAND Output (Y1/Y2/Y3/Y4) | Pull-up/pull-down capable CMOS outputs - drive downstream logic or analog comparators directly |
| 7 | GND | Ground reference for all logic stages and internal bias networks - must be low-impedance for stable hysteresis |
| 14 | VCC | Primary supply rail - powers all four gates and internal hysteresis circuitry; tolerant of 6.5 V max transient |
Key Features
| Feature | Design Value |
|---|---|
| High Noise Immunity | VNIH = VNIL = 28% VCC - rejects common-mode noise on long traces or unshielded cables |
| Power-Down Input Protection | Inputs remain high-impedance and non-latching when VCC = 0 V - prevents back-driving during partial power-down |
| Level Translation Capability | Accepts 3.3 V logic inputs while delivering full 5.0 V CMOS output swings - eliminates need for discrete translators |
| Latchup Immunity | >100 mA latchup current rating - withstands transient overcurrent events without destructive failure |
| Low Dynamic Noise | VOLP ≤ 0.8 V (max) - minimizes ground bounce and crosstalk in dense PCB layouts |
Applications
| Industrial Sensor Interface | Automotive Body Control |
|---|---|
Use Scenario: Conditioning slow-rising analog sensor outputs (e.g., thermistor-based temperature monitors) into clean digital signals for microcontroller ADC triggering. IC Role / Device Role / Timing Role: Schmitt-trigger NAND acts as edge-squaring line receiver, converting noisy or sluggish analog thresholds into precise logic transitions. Use Value: Eliminates external RC filtering and comparator stages, reducing BOM count and board area while improving timing predictability. | Use Scenario: Debouncing mechanical switch inputs (e.g., door lock actuators, seat position sensors) before feeding to vehicle body control module. IC Role / Device Role / Timing Role: Quad NAND provides independent hysteresis per switch channel, rejecting contact bounce and EMI in 12 V automotive environments. Use Value: Enables direct connection of unconditioned switches to MCU GPIOs without firmware debouncing overhead or external components. |
| Legacy System Upgrade | IoT Edge Node Signal Conditioning |
Use Scenario: Interfacing 5 V TTL legacy peripherals (e.g., RS-232 line drivers, optocoupler outputs) with modern 3.3 V microcontrollers. IC Role / Device Role / Timing Role: Level translator leveraging VCC = 5 V and 3.3 V-tolerant inputs - accepts TTL logic levels while driving full-swing CMOS outputs. Use Value: Avoids dedicated level-shifter ICs or resistor-divider networks, simplifying design and ensuring deterministic timing margins. | Use Scenario: Cleaning up RF-sensitive GPIO signals (e.g., PIR motion detector outputs, environmental sensor alerts) in battery-powered smart home nodes. IC Role / Device Role / Timing Role: Low-power Schmitt NAND gate suppresses EMI-induced false triggers and stabilizes wake-up event detection. Use Value: Reduces false wake-ups and extends battery life by eliminating software-based filtering and enabling hardware-triggered interrupts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger NAND applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV132APWR | Lower VCC range (2.0–5.5 V), higher ICC (max 20 µA vs. 2 µA), same SOIC-14 pinout | Optimized for LV logic families; less suitable for mixed 3.3 V/5.0 V translation due to reduced output swing at 3.3 V | Select when prioritizing TI ecosystem compatibility and lower cost over ultra-low quiescent current |
| 74LVC132PW,118 | Wider operating temp (−40°C to +125°C), identical hysteresis and propagation delay, TSSOP-14 only | Requires PCB redesign for TSSOP footprint; better suited for space-constrained designs needing extended temperature range | Select when board space is critical and thermal environment exceeds −55°C to +125°C spec of MC74VHC132MELG |
Compared with SN74LV132APWR and 74LVC132PW,118, MC74VHC132MELG offers superior quiescent current (2 µA max), broader industrial temperature support (−55°C to +125°C), and native 5.0 V output swing - making it optimal for legacy interface and high-reliability signal conditioning where power and noise immunity are primary constraints.

FAQ
What is the maximum supply voltage for MC74VHC132MELG?
The absolute maximum DC supply voltage (VCC) for MC74VHC132MELG is +6.5 V, though recommended operation is limited to 2.0 V to 5.5 V. Exceeding 6.5 V risks permanent damage. This headroom allows safe handling of transient overvoltages in industrial environments without external clamping.
Does MC74VHC132MELG support 3.3 V input signals when powered at 5.0 V?
Yes, MC74VHC132MELG accepts 3.3 V logic inputs while operating at VCC = 5.0 V. Its input structure tolerates voltages up to 5.5 V and exhibits CMOS-compatible thresholds - enabling seamless 3.3 V-to-5.0 V level translation without external components.
What is the hysteresis voltage (VH) of MC74VHC132MELG at 5.0 V supply?
At VCC = 5.0 V, the typical hysteresis voltage (VH) of MC74VHC132MELG is 0.50 V, with a minimum of 0.30 V and maximum of 1.60 V across temperature. This ensures robust noise rejection for signals with slow edges or high EMI exposure in industrial settings.
Can MC74VHC132MELG be used as a standalone line receiver?
Yes, MC74VHC132MELG is explicitly designed as a line receiver for slow input signals. Its Schmitt-trigger inputs eliminate chatter from noisy or slowly transitioning waveforms - making it ideal for direct connection to mechanical switches, analog comparators, or long cable runs without external filtering.
Is MC74VHC132MELG RoHS compliant and Pb-free?
Yes, MC74VHC132MELG is Pb-free and RoHS compliant, as confirmed in the official onsemi datasheet (Rev. 8, February 2024). The "G" suffix in the part marking indicates compliance, and the SOIC-14 package uses lead-free terminations meeting JEDEC J-STD-020 standards.
