Product details
Overview
74VCX132MX from Fairchild Semiconductor is a low-voltage quad 2-input NAND gate IC with Schmitt trigger inputs, 1.4V–3.6V VCC operation, 3.6V-tolerant I/O, and 3.3 ns max propagation delay at 3.3V. It delivers noise-immune signal conditioning in mixed-voltage digital interfaces, such as level-shifting between 1.8V/2.5V logic domains and noisy sensor input conditioning.
For engineers reviewing the 74VCX132MX datasheet, pinout, applications, or equivalent options, key selection criteria include hysteresis voltage (0.3–1.2 V), output drive strength (±24 mA @ 3.0V), power-off high-impedance behavior, Quiet Series™ EMI reduction, and DQFN-14 package compatibility with space-constrained PCB layouts.
Technical Context
The 74VCX132MX implements four independent NAND gates, each with asymmetric input thresholds enabling hysteresis-positive-going Vt+ ranges from 1.2 V to 2.2 V and negative-going Vt− from 0.2 V to 0.8 V depending on VCC. This architecture converts slow-rising or noisy analog-like signals into clean digital edges without external RC networks.
It operates across 1.4V–3.6V supply rails while maintaining full 3.6V I/O tolerance, allowing direct interfacing with legacy 3.3V systems even when powered from 1.8V. Its Quiet Series™ circuitry suppresses simultaneous switching noise, reducing dynamic ground bounce and radiated emissions during high-speed transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.4V to 3.6V - enables dual-supply domain bridging (e.g., 1.8V core ↔ 3.3V I/O) |
| Input Hysteresis (ΔVt) | 0.3V to 1.2V - rejects noise up to ±600 mV on slow-switching inputs like mechanical switches or analog sensors |
| tPD Max | 3.3 ns @ VCC = 3.3V, CL = 30 pF - supports >100 MHz toggle rates in clean-edge generation paths |
| IOH/IOL | ±24 mA @ 3.0V - drives multiple standard CMOS loads or small LEDs without external buffers |
| I/O Voltage Tolerance | 3.6V - allows safe connection to 3.3V buses while operating from 1.8V supply, eliminating level shifters |
| Power-off High-Z | Inputs and outputs enter high-impedance state when VCC = 0V - prevents back-driving and bus contention in hot-swap or power-gated systems |
| ESD Rating | HBM ≥ 2000V - withstands handling in non-ESD-controlled assembly environments |
Pinout & Package
Packaged in a Pb-free, leadless 14-terminal DQFN (JEDEC MO-241, 2.5 × 3.0 mm) with wettable flank terminations for automated optical inspection. The DQFN footprint minimizes board area and improves thermal performance over SOIC/TSSOP variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 12, 13 | Input (A1/B1, A2/B2, A3/B3, A4/B4) | Four independent NAND input pairs; Schmitt-triggered for noise rejection |
| 3, 6, 10, 11 | Output (Y1, Y2, Y3, Y4) | Active-low NAND outputs; 3.6V-tolerant, ±24 mA drive capability |
| 7 | GND | Ground reference for all logic and I/O; must be low-inductance connection |
| 14 | VCC | Primary power supply (1.4V–3.6V); decoupling capacitor required within 5 mm |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt Trigger Inputs | Enables reliable edge detection on slow or noisy signals (e.g., pushbutton debouncing, thermistor interface) |
| 3.6V-Tolerant I/O | Permits interoperability with 3.3V peripherals while powered from 1.8V/2.5V rails-no external level translators needed |
| Quiet Series™ EMI Reduction | Reduces simultaneous switching output (SSO) noise by controlling slew rate and internal current steering |
| Power-Off High-Z | Prevents current leakage or bus contention during power sequencing or standby modes |
| Latchup Immunity | Exceeds JEDEC JESD78 Class II (≥100 mA) - robust against transient-induced latchup in industrial environments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate with Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC132APWR | Same 14-pin TSSOP package; lower hysteresis (0.1V typ), no 3.6V I/O tolerance - requires VCC-referenced I/O | Best suited for pure 3.3V-only systems; unsuitable for mixed-voltage interfacing | Select when cost is prioritized over voltage flexibility and EMI performance |
| 74AUP1G132GW,125 | Single-gate SOT353 package; ultra-low ICC (0.9 µA), but only ±4 mA drive and no 3.6V tolerance | Targeted at battery-powered IoT nodes requiring nanowatt sleep current, not multi-gate signal conditioning | Select for ultra-low-power, space-constrained designs where only one NAND function is needed |
Compared with SN74LVC132APWR and 74AUP1G132GW,125, the 74VCX132MX uniquely combines quad-gate density, 3.6V I/O tolerance, and Quiet Series™ EMI suppression-making it optimal for compact, mixed-voltage industrial control boards where signal integrity and layout simplicity are critical.

FAQ
What is the minimum supply voltage for reliable operation of the 74VCX132MX?
The 74VCX132MX is specified to operate down to 1.4V VCC, with guaranteed DC and AC performance including hysteresis and output drive. At 1.4V, output sink/source capability drops to ±2 mA, sufficient for driving high-impedance CMOS inputs but not LEDs or transmission lines. Full ±24 mA drive requires ≥3.0V VCC.
Does the 74VCX132MX require external pull-up or pull-down resistors on unused inputs?
Yes - per Fairchild's Recommended Operating Conditions, floating or unused inputs on the 74VCX132MX must be held HIGH or LOW to prevent increased ICC, oscillation, or undefined output states. Schmitt trigger inputs do not eliminate this requirement; they only improve noise margin on actively driven inputs.
Can the 74VCX132MX safely interface with a 5V microcontroller GPIO?
No - although the 74VCX132MX tolerates up to 3.6V on inputs and outputs, applying 5V violates its Absolute Maximum Rating of 4.6V and risks permanent damage. For 5V system interfacing, use a dedicated level shifter or a 5V-tolerant logic family such as 74LVT or 74ALVC.
Is the 74VCX132MX pin-compatible with the standard 74HC132 in SOIC-14?
Yes - the 74VCX132MX shares identical pin assignments with the 74HC132 in SOIC-14 (M14A) and TSSOP-14 (MTC14) packages. However, the DQFN-14 variant (74VCX132BQX) has different pad layout and is not mechanically interchangeable. Always verify package-specific footprint before substitution.
What does "Quiet Series™" mean for the 74VCX132MX in practical design terms?
Quiet Series™ refers to Fairchild's proprietary output-stage design that reduces simultaneous switching noise (SSN) by controlling current slew rate and minimizing ground bounce. In practice, this means the 74VCX132MX generates less radiated EMI and causes fewer signal integrity issues on shared power/ground planes compared to standard VCX or HC logic, easing EMC compliance.
