Product details
Overview
74VCX132MTCX 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 sensor input stages in industrial PLCs.
For engineers reviewing the 74VCX132MTCX 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 TSSOP-14 package compatibility with 4.4 mm width and JEDEC MO-153 footprint.
Technical Context
The 74VCX132MTCX implements four independent NAND gates, each with asymmetric input thresholds enabling clean edge regeneration of slow-rising or noisy signals. Its Schmitt-trigger hysteresis (VH = 0.3–1.2 V) ensures reliable switching across 1.4V–3.6V supply range without external components.
All inputs and outputs tolerate up to 3.6V regardless of VCC, supporting mixed-supply interfacing between 1.8V/2.5V/3.3V domains. The device features power-off high-impedance I/O, ±24 mA drive capability at 3.0V, and patented Quiet Series™ circuitry to suppress simultaneous switching noise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.4V to 3.6V - enables direct interface with 1.8V, 2.5V, and 3.3V logic families without level shifters |
| tPD Max | 3.3 ns @ 3.3V - supports >100 MHz toggle rates in timing-critical control paths |
| I/O Voltage Tolerance | Up to 3.6V - allows safe connection to higher-voltage peripherals even when VCC = 1.4V |
| IOH/IOL | ±24 mA @ VCC = 3.0V - drives standard 50 Ω transmission lines or multiple CMOS loads |
| VH (Hysteresis) | 0.3 V to 1.2 V - rejects up to 1.2 V peak-to-peak noise on slow-switching analog-like inputs |
| CIN/COUT | 6.0 pF / 7.0 pF - minimizes capacitive loading on source and load nodes in high-speed routing |
| Power-off Z-state | True high-impedance I/O - prevents back-driving or leakage during system sleep or hot-swap events |
Pinout & Package
74VCX132MTCX is packaged in a 14-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153 compliant, 4.4 mm wide, with 0.65 mm lead pitch and exposed pad not present. Pin assignments follow standard 74-series logic layout for quad 2-input NAND functions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 1B / 2A, 2B / 3A, 3B / 4A, 4B | Input pairs per gate | Schmitt-trigger inputs with hysteresis; accept 0–3.6V signals independent of VCC |
| 1Y, 2Y, 3Y, 4Y | Output per gate | NAND-computed outputs with 3.6V-tolerant push-pull structure and ±24 mA drive |
| VCC | Positive supply | 1.4V–3.6V logic supply; powers internal circuitry and defines output HIGH level |
| GND | Ground reference | Return path for all I/O and internal currents; must be low-impedance for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | 0.3–1.2 V hysteresis enables robust recovery of degraded or noisy waveforms (e.g., mechanical switch bounce, long PCB traces) |
| 3.6V-tolerant I/O | Allows interoperability with legacy 3.3V/5V peripherals while operating from 1.4V–3.6V supplies - no external clamping needed |
| Quiet Series™ EMI reduction | Patented output slew-rate control lowers simultaneous switching noise by >50% vs. standard VCX gates |
| Power-off high-Z | I/O pins enter true high-impedance state when VCC = 0V - eliminates back-powering and bus contention during power sequencing |
| JEDEC MO-153 TSSOP | Industry-standard 14-pin TSSOP footprint (4.4 mm width) ensures drop-in replacement in existing layouts and automated assembly compatibility |

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 |
|---|---|---|---|
| SN74LVC132APW | Same 14-pin TSSOP package; 1.65V–3.6V VCC; lower hysteresis (0.2–0.8 V); no 3.6V I/O tolerance | Requires external clamping for 3.3V inputs when VCC < 3.3V; unsuitable for true mixed-voltage bus interfacing | Select when only 1.8V/3.3V domain bridging is needed and cost is prioritized over I/O tolerance |
| 74AUP1G132GW | Single-gate SOT353 package; 0.8V–3.6V VCC; 3.6V-tolerant I/O; tPD = 6.4 ns @ 3.0V | Not quad-function; requires four devices for same logic density; higher propagation delay limits high-speed use | Select for ultra-low-power, space-constrained designs where gate count flexibility outweighs propagation speed needs |
Compared with SN74LVC132APW and 74AUP1G132GW, the 74VCX132MTCX uniquely combines quad NAND density, full 3.6V I/O tolerance down to 1.4V VCC, and sub-3.5 ns propagation - making it optimal for compact, mixed-voltage industrial control nodes requiring both noise immunity and timing integrity.

FAQ
What is the minimum supply voltage for reliable operation of the 74VCX132MTCX?
The 74VCX132MTCX guarantees full functionality down to 1.4V VCC, including specified propagation delay, output drive, and Schmitt-trigger hysteresis. Below 1.4V, parameters such as tPD and IOH/IOL are not characterized. For battery-powered applications, this enables direct operation from single-cell lithium or NiMH sources without regulation.
Does the 74VCX132MTCX support hot insertion or live I/O connection?
Yes - the 74VCX132MTCX features true 3.6V-tolerant inputs and outputs, meaning it can safely accept signals up to 3.6V regardless of whether VCC is powered or at 0V. This enables hot-plug capability in modular systems, provided GND is established first and current-limiting resistors are used per IIK/IOK limits in the datasheet.
How does the Schmitt-trigger hysteresis in the 74VCX132MTCX improve noise immunity compared to standard NAND gates?
The 74VCX132MTCX provides 0.3–1.2 V of input hysteresis (VH), creating separate thresholds for rising (Vt+) and falling (Vt−) transitions. This prevents oscillation on slowly changing or noisy inputs - for example, rejecting up to 1.2 Vpp interference on a 3.3V signal - whereas standard NAND gates would chatter or produce multiple edges under identical conditions.
Is the 74VCX132MTCX pin-compatible with other 74-series quad NAND packages?
Yes - the 74VCX132MTCX uses the industry-standard 14-pin TSSOP pinout (JEDEC MO-153), matching the pin assignments of 74HC132, 74LV132, and 74LVC132 in SOIC and TSSOP variants. This allows direct PCB replacement where voltage and timing requirements align, though VCC range and I/O tolerance differ.
What thermal and environmental ratings apply to the 74VCX132MTCX?
The 74VCX132MTCX is rated for free-air operating temperature from –40°C to +85°C and storage from –65°C to +150°C. It meets JEDEC J-STD-020B for Pb-free reflow and exceeds JEDEC 78 for latch-up immunity. ESD protection is rated at ≥2000V HBM and ≥250V MM, validated per manufacturer test reports.
