Product details
Overview
74LVX132MTR from STMicroelectronics is a low-voltage CMOS quad 2-input Schmitt NAND gate with 5V-tolerant inputs, operating from 2V to 3.6V supply, featuring 5.9ns typical propagation delay at 3.3V, 0.7V typical hysteresis, and ±4mA symmetrical output drive-used in noise-immune signal conditioning for 3.3V/5V mixed-voltage interface circuits.
For engineers reviewing the 74LVX132MTR datasheet, 74LVX132MTR pinout, 74LVX132MTR application, or 74LVX132MTR equivalent, key selection criteria include input hysteresis voltage (0.3–1.2V), 5V-tolerant input capability, quiescent current ≤2µA, symmetrical tPLH/tPHL delay matching, and SO-14 package compatibility with legacy 74-series logic footprints.
Technical Context
The device implements four independent Schmitt-trigger NAND gates using sub-micron C2MOS technology, each with built-in hysteresis (Vt+ = 2.2V, Vt− = 0.9V at VCC = 3.0V) to reject slow-rising/falling noise on input lines. Inputs accept 0–7V regardless of VCC, enabling robust level translation between 5V and 3.3V domains.
It features power-down protection on all inputs, 2kV ESD immunity per IEC 61000-4-2, and balanced output impedance (|IOH| = IOL ≥ 4mA). Dynamic noise suppression includes VOLP = 0.3V (typ.) and VIHD/VILD thresholds tightly specified at 2.2V/0.9V under 3.3V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0V to 3.6V - supports battery-powered 3.3V systems with 1.2V data retention |
| tPD (Typ) | 5.9ns at VCC = 3.3V, CL = 15pF - enables high-speed digital interfacing in compact timing-critical paths |
| Hysteresis (VH) | 0.3V to 1.2V - ensures reliable noise margin against EMI-induced glitches on slow edges |
| Input Tolerance | 0V to 7V - allows direct connection to 5V logic without external level shifters |
| ICC (Max) | 20µA at TA = −40°C to +85°C - minimizes standby power in always-on sensor nodes |
| Output Drive | ±4mA min - sustains clean logic transitions driving 50pF loads across temperature |
| VOLP (Typ) | 0.3V at VCC = 3.3V - reduces ground bounce and crosstalk in dense PCB layouts |
Pinout & Package
74LVX132MTR is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package, 3.9mm wide, with standard 1.27mm pitch and gull-wing leads. Pin 1 marked by notch or bevel; pin 7 = GND, pin 14 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A–4A | Independent Schmitt NAND input A for each gate - accepts 0–7V, immune to floating states |
| 2, 5, 10, 13 | 1B–4B | Independent Schmitt NAND input B for each gate - provides dual-threshold noise rejection |
| 3, 6, 8, 11 | 1Y–4Y | CMOS push-pull outputs - deliver rail-to-rail swing with matched rise/fall times |
| 7 | GND | Logic ground reference - decoupling capacitor placement critical for VOLP control |
| 14 | VCC | Positive supply - must be stabilized within 2V–3.6V; powers internal protection diodes |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs with hysteresis | Enables reliable switching on slow or noisy signals (e.g., mechanical switch debouncing, analog sensor thresholds) |
| 5V-tolerant inputs | Eliminates need for external level translators when interfacing legacy 5V microcontrollers or peripherals |
| Low dynamic noise (VOLP = 0.3V) | Reduces simultaneous switching noise in multi-gate logic arrays and mixed-signal PCBs |
| Power-down input protection | Permits safe hot-plug operation and zero-current draw when VCC = 0V, even with live inputs |
| ESD immunity (2kV HBM) | Meets industrial handling requirements without additional transient protection components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV132APWR | TI part with identical SO-14 pinout, 2V–5.5V VCC range, but lower hysteresis (0.2V typ) and higher ICC (10µA max) | Less effective on very slow edges; suitable where wider supply range outweighs noise margin needs | Prefer when system uses 5V logic rails or requires extended VCC flexibility |
| 74LVC132PW,118 | Nexperia part in TSSOP14; same 1.65V–3.6V range, but tighter VOLP (0.2V typ) and higher ESD rating (4kV HBM) | Better noise performance in high-density layouts; not pin-compatible with SO-14 footprint | Choose for space-constrained PCBs where TSSOP is acceptable and enhanced ESD is critical |
Compared with SN74LV132APWR and 74LVC132PW,118, the 74LVX132MTR offers superior hysteresis (0.3–1.2V) and lowest quiescent current (2µA), making it optimal for ultra-low-power, noise-prone 3.3V interfaces where SO-14 packaging is required.

FAQ
Can 74LVX132MTR operate with VCC = 1.8V?
No. The recommended operating VCC range is 2.0V to 3.6V. At 1.8V, the device may fail to meet guaranteed hysteresis, propagation delay, or output drive specifications. Data retention is supported down to 1.2V, but functional operation is not assured below 2.0V.
Is 74LVX132MTR pin-compatible with standard 74HC132?
Yes-pinout and logic function match the 74-series 132 family. However, 74LVX132MTR has Schmitt-trigger inputs (unlike HC132's non-hysteresis inputs), and operates only up to 3.6V VCC versus HC132's 6V maximum. Direct replacement requires verifying supply voltage and noise environment.
What is the maximum capacitive load this device can drive reliably?
The AC specs guarantee tPLH/tPHL performance up to 50pF load capacitance. Driving >50pF may increase propagation delay and degrade VOLP/VOLV margins. For loads exceeding 50pF, add series termination or buffer stages to maintain signal integrity and timing compliance.
Does 74LVX132MTR require external pull-up or pull-down resistors on unused inputs?
No. Unused inputs may be tied directly to VCC or GND. Due to built-in power-down protection and high-impedance inputs, floating inputs are electrically unsafe and must be avoided-but no external resistors are needed if properly terminated to rail.
