Product details
Overview
M74HC132TTR from STMicroelectronics is a high-speed CMOS quad 2-input Schmitt-trigger NAND gate in TSSOP-14 package, operating from 2V to 6V supply, with typical propagation delay of 11ns at 6V, hysteresis voltage of 1.2V (typ.) at 4.5V, and output drive capability of ±4mA. It enables robust signal conditioning in noisy industrial sensor interfaces.
For engineers reviewing the M74HC132TTR datasheet, M74HC132TTR pinout, M74HC132TTR application, or M74HC132TTR equivalent, key selection criteria include input hysteresis width (≥1.1V at VCC=4.5V), symmetrical output impedance, wide VCC range (2–6V), and guaranteed operation from –55°C to +125°C.
Technical Context
The M74HC132TTR implements four independent Schmitt-trigger NAND gates using silicon-gate C2MOS technology, each with input hysteresis of ~20% VCC-enabling clean digital conversion of slow-rising or noisy analog-like signals. Its TTL-compatible input thresholds (VP ≈ 2.7V, VN ≈ 1.6V at VCC = 4.5V) ensure reliable logic interpretation across temperature.
All inputs feature integrated ESD protection circuits, and outputs deliver balanced rise/fall times (tPLH ≅ tPHL) and matched |IOH|/IOL (≥4mA min). The device is functionally and pin-compatible with the standard 74HC00 but adds Schmitt-trigger input behavior for noise immunity.
Key Specifications

|---|---|
| VCC Range | 2V to 6V - supports single-supply operation across battery-powered and industrial 3.3V/5V systems |
| Propagation Delay | 11ns (typ.) at VCC=6V - enables ≥30MHz toggle rates in clocked logic paths |
| Hysteresis Voltage | 1.1V (min.) at VCC=4.5V - rejects >1.1V peak-to-peak noise on input signals |
| Output Drive | ±4mA (min.) - directly drives LED indicators or fan-out to ≥10 74HC inputs |
| Input Leakage | ±1µA (max.) at TA=125°C - preserves signal integrity in high-impedance sensor node interfaces |
| Operating Temp | –55°C to +125°C - qualified for under-hood automotive and industrial control environments |
| Quiescent ICC | 10µA (max.) at TA=85°C - enables ultra-low-power wake-up detection in always-on circuits |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A–4A Inputs | Schmitt-trigger NAND gate inputs; accept slow or noisy signals with hysteresis |
| 2, 5, 10, 13 | 1B–4B Inputs | Second inputs per gate; identical hysteresis and threshold behavior |
| 3, 6, 8, 11 | 1Y–4Y Outputs | Active-low NAND outputs; rail-to-rail swing, symmetrical sourcing/sinking |
| 7 | GND | Digital ground reference; decoupling capacitor must be placed adjacent |
| 14 | VCC | Positive supply (2–6V); requires local 100nF ceramic bypass near pin |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | 20% VCC hysteresis ensures noise rejection without external RC components |
| Pin-compatible with 74HC00 | Drop-in replacement for standard NAND gates when hysteresis is required |
| Wide VCC range (2–6V) | Eliminates level-shifting between 3.3V microcontrollers and 5V legacy peripherals |
| Balanced propagation delays | tPLH ≅ tPHL minimizes duty-cycle distortion in clocked signal conditioning |
| ESD-protected inputs | Withstands ±2kV HBM - reduces need for external TVS in exposed I/O designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC132DR | Same logic function and hysteresis; SOIC-14 package (larger footprint, higher thermal resistance) | Preferred for prototyping or through-hole rework; not suitable for space-constrained PCBs | Select when board layout allows SOIC and thermal dissipation >450mW is needed |
| 74LVC132PW | Lower VCC range (1.65–5.5V); higher drive (±24mA); no guaranteed operation below –40°C | Optimized for 3.3V-only portable systems; lacks extended temperature qualification | Select only for commercial-temp consumer designs requiring higher drive strength |
Compared with SN74HC132DR and 74LVC132PW, the M74HC132TTR uniquely combines TSSOP-14 miniaturization, full –55°C to +125°C qualification, and 2–6V flexibility-making it optimal for space- and reliability-critical industrial and automotive control nodes.

FAQ
Is M74HC132TTR compatible with 3.3V microcontroller GPIOs?
Yes. With VCC = 3.3V, its input thresholds (VP ≈ 1.7V, VN ≈ 0.9V) and output VOH/VOL levels meet 3.3V LVTTL logic requirements. It accepts 3.3V inputs directly and drives 3.3V loads with ≥4mA sink/source, eliminating level shifters in mixed-voltage systems.
What is the maximum capacitive load this device can drive reliably?
The M74HC132TTR is characterized up to CL = 50pF in AC specs. At 6V VCC and 25°C, it maintains tPLH/tPHL ≤27ns into 50pF. For loads >50pF, propagation delay increases linearly-designers should limit total net capacitance to ≤75pF for timing-critical paths.
Does this part support hot insertion or live circuit connection?
No. M74HC132TTR lacks hot-swap protection features such as power-up/down sequencing or Ioff. Connecting while powered may cause bus contention or latch-up due to uncontrolled input voltage transitions. Always power-cycle the system before inserting or removing the device.
How does its hysteresis compare to standard 74HC14 inverters?
At VCC = 4.5V, M74HC132TTR offers VH ≈ 1.1V (min.), matching the 74HC14's typical hysteresis. However, unlike the inverter, it provides NAND logic functionality-enabling two-input noise-immune gating without adding external inverters or pull-ups.
