Product details
Overview
MC74LVX132MG from onsemi is a quad 2-input Schmitt-trigger NAND gate in TSSOP-14 package, operating at 2.0–3.6 V supply, with 5.8 ns typical propagation delay at 3.3 V and ±25 mA output drive capability. It enables robust noise-immune signal conditioning in mixed-voltage digital interfaces between 3.0 V and 5.0 V systems.
For engineers reviewing the MC74LVX132MG datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, validated pin functions, real-world use cases for hysteresis-based signal cleanup, and two confirmed alternative logic devices with documented functional and parametric differences.
Technical Context
The MC74LVX132MG implements four independent Schmitt-trigger NAND gates using silicon-gate CMOS technology. Each gate features input hysteresis (typical 0.3–1.6 V depending on VCC), enabling reliable squaring of slow-rising or noisy signals without oscillation.
Its inputs tolerate up to 6.5 V, allowing direct interfacing between 3.3 V logic domains and legacy 5.0 V systems. The device includes power-down input protection and exceeds 300 mA latchup immunity per JEDEC JESD78.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger NAND logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV132APWR | Same 2.0–5.5 V supply range; 7.5 ns tPD @ 3.3 V; no 6.5 V input tolerance | Lacks overvoltage input protection - requires external clamping for 5 V interface use | Select when full 5.5 V operation is needed but 6.5 V tolerance is unnecessary and cost is prioritized |
| 74LVC132PW,118 | 3.3 V only (1.65–3.6 V); 5.2 ns tPD @ 3.3 V; 5.5 V tolerant inputs | Lower VCC min enables single-supply 1.8 V/3.3 V mixed systems; not suitable for 2.0 V-only rails | Choose for ultra-low-power IoT edge nodes where 1.8 V compatibility and sub-5 ns speed outweigh input overvoltage needs |
Compared with SN74LV132APWR and 74LVC132PW,118, the MC74LVX132MG uniquely combines 2.0 V minimum operation, 6.5 V input tolerance, and Schmitt-trigger hysteresis - making it the only option among the three for robust 3.3 V/5.0 V boundary interfacing in harsh industrial environments without added protection components.

FAQ
What is the minimum supply voltage for reliable operation of the MC74LVX132MG?
The MC74LVX132MG is specified for reliable operation down to 2.0 V supply voltage, as confirmed in the Recommended Operating Conditions table. At 2.0 V, its positive input threshold (VT+) remains ≥1.15 V and propagation delay stays within datasheet limits - enabling use in battery-powered systems with brown-out conditions or multi-rail power architectures where 3.3 V may dip transiently.
Does the MC74LVX132MG support direct connection to 5 V logic inputs?
Yes, the MC74LVX132MG supports direct connection to 5 V logic inputs because its absolute maximum input voltage rating is +6.5 V, and its recommended input voltage range extends to 5.5 V. This allows safe interfacing with 5 V microcontrollers, sensors, or transceivers without external level-shifting components - a key differentiator versus standard LV logic families.
How does the Schmitt-trigger input hysteresis of the MC74LVX132MG improve noise immunity?
The MC74LVX132MG's Schmitt-trigger inputs provide 0.30–1.60 V hysteresis (VT+ − VT−), meaning the rising and falling input thresholds differ significantly. This prevents multiple output transitions when input signals cross the threshold slowly or with superimposed noise - a critical advantage in industrial environments with EMI, long cables, or unshielded sensor wiring where standard NAND gates would oscillate.
What is the maximum output current drive capability of the MC74LVX132MG?
The MC74LVX132MG delivers ±25 mA DC output current per pin, verified in the Maximum Ratings table. This allows direct driving of moderate capacitive loads (e.g., 50 pF traces), LEDs with series resistors, or fan-out to up to 10 standard CMOS inputs - eliminating need for external buffers in many interface applications.
Is the MC74LVX132MG pin-compatible with the standard MC74LVX00?
Yes, the MC74LVX132MG has identical pin configuration and function to the MC74LVX00 quad 2-input NAND gate, as explicitly stated in the datasheet: "Pin configuration and function are the same as the MC74LVX00, but the inputs have hysteresis." This allows drop-in replacement in existing designs where Schmitt-trigger behavior is added without PCB redesign.
