Product details
Overview
M74HC132YTTR 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, ±4mA symmetrical output drive, and input hysteresis of ~1.2V at 5V - used for noise-immune signal conditioning in digital interface circuits.
For engineers reviewing the M74HC132YTTR datasheet, M74HC132YTTR pinout, M74HC132YTTR application, or M74HC132YTTR equivalent, key selection criteria include Schmitt-trigger input thresholds (VP/VN), hysteresis voltage (VH), output drive capability at VCC = 4.5V/6V, temperature range (-55°C to +125°C), and TSSOP-14 thermal derating (6.1mW/°C).
Technical Context
The M74HC132YTTR implements four independent Schmitt-trigger NAND gates using silicon-gate C2MOS technology, each with hysteresis (~20% VCC) enabling clean edge regeneration from slow or noisy inputs. Its symmetrical output impedance ensures matched tPLH/tPHL delays (≤27ns max at 6V, -55°C to +125°C).
All inputs feature ESD and transient overvoltage protection. The device is functionally and pin-compatible with standard 74-series 132 logic, supporting direct replacement in legacy HC designs while delivering improved noise immunity and rail-to-rail operation across 2–6V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Operating Range | 2V to 6V - supports mixed-voltage system interfacing (e.g., 3.3V logic driving 5V-tolerant loads) |
| Propagation Delay (tPD) | 11ns (typ.) at VCC = 6V - enables reliable timing in ≤30MHz digital control loops |
| Hysteresis Voltage (VH) | 0.8–1.7V (varies with VCC) - rejects up to ~1.7V of low-frequency noise on input signals |
| Output Drive (IOH/IOL) | ±4mA min at VCC = 4.5V - sufficient to drive multiple 74HC inputs or small capacitive loads (<50pF) |
| Quiescent ICC | 1µA max at TA = 25°C - enables ultra-low-power standby in battery-backed systems |
| Operating Temperature | -55°C to +125°C - qualified for automotive under-hood and industrial motor-control environments |
Pinout & Package
TSSOP-14 (4.9 × 6.4 mm, 0.65 mm pitch), thin shrink small outline package with exposed pad not present; optimized for automated SMT assembly and moderate power dissipation (450 mW @ 65°C, derated 6.1 mW/°C above).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | Input A (Gate 1–4) | Schmitt-triggered NAND input; accepts slow-rising/falling signals without oscillation |
| 2, 5, 10, 13 | Input B (Gate 1–4) | Second Schmitt-triggered NAND input per gate; hysteresis centered at VP/VN thresholds |
| 3, 6, 8, 11 | Output Y (Gate 1–4) | Push-pull CMOS output; drives high/low with matched rise/fall times (tTLH ≈ tTHL) |
| 7 | GND | Logic ground reference; must be low-impedance return path for all output switching currents |
| 14 | VCC | Positive supply; decoupling capacitor (100nF) required within 5 mm for stable AC performance |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables robust debouncing of mechanical switches and recovery of degraded clock/data edges |
| Pin/function compatibility with 74HC132 | Direct drop-in replacement in existing PCB layouts without redesign or firmware change |
| Balanced propagation delays (tPLH ≅ tPHL) | Maintains 50% duty cycle integrity in clocked logic paths and oscillator feedback loops |
| High noise immunity (VH ≈ 1.2V @ 5V) | Rejects common-mode noise on long traces or shared I/O lines in industrial PLC backplanes |
Applications
| Industrial Sensor Interface | Automotive Body Control |
|---|---|
Use Scenario: Converting noisy analog sensor outputs (e.g., thermistor voltage dividers) into clean digital logic levels for microcontroller ADC trigger or interrupt generation. IC Role / Device Role / Timing Role: Signal conditioner and noise filter at front-end of data acquisition chain. Use Value: Eliminates need for external RC filtering and software debouncing, reducing BOM count and firmware latency. | Use Scenario: Debouncing door switch, trunk latch, or seat position sensor signals before routing to body control module (BCM) MCU inputs.

IC Role / Device Role / Timing Role: Level-shifting logic element with hysteresis to tolerate slow slew rates from older ASICs. Use Value: Avoids timing violations caused by marginal rise/fall times in mixed-technology interconnects. | Use Scenario: Replacing obsolete 74LS132 in aging test equipment or medical device control panels requiring extended temperature support. IC Role / Device Role / Timing Role: Pin-identical functional upgrade with lower power and wider VCC range. Use Value: Extends product lifecycle without PCB rework; supports modern 3.3V supply rails while retaining LS logic behavior. |
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, SOIC-14 package; higher thermal resistance (7 mW/°C derating); no TSSOP footprint | Preferred for through-hole prototyping or boards lacking fine-pitch SMT capability | Select when board assembly process does not support TSSOP or thermal margin exceeds 450 mW |
| 74LVC132PW | Lower VCC range (1.65–5.5V); higher speed (tPD = 7.1ns typ. @ 3.3V); different input thresholds (Vhys ≈ 0.5V @ 3.3V) | Better suited for 3.3V-only systems with tight timing budgets and lower noise margin requirements | Select only if system operates strictly at 3.3V and requires sub-10ns delay; not drop-in for 5V or mixed-rail use |
Compared with SN74HC132DR and 74LVC132PW, the M74HC132YTTR uniquely balances wide supply range (2–6V), robust hysteresis (≥1.2V at 5V), and TSSOP-14 space efficiency - making it optimal for retrofitting legacy 5V designs into compact, thermally constrained industrial modules.

FAQ
What is the maximum input frequency supported by M74HC132YTTR?
The M74HC132YTTR has no specified maximum clock frequency, as it is a combinational logic device. Its usable input edge rate is limited by propagation delay (≤27ns max) and transition time (≤22ns max), supporting clean signal conditioning up to ~15 MHz for square-wave inputs with CL = 50 pF. Higher frequencies require verification with actual load and layout.
Can M74HC132YTTR operate reliably at 3.3V supply?
Yes - the M74HC132YTTR is fully specified from 2V to 6V, including 3.3V operation. At VCC = 3.3V, typical hysteresis is ~0.7V, VOH ≥ 3.15V, VOL ≤ 0.33V (at IOL = 4mA), and propagation delay is ≤26ns over full temperature range, meeting standard 3.3V HC logic interface requirements.
Does M74HC132YTTR have built-in ESD protection?
Yes - all inputs include integrated protection circuits against static discharge and transient overvoltage, rated to ±20mA DC input diode current per pin. It meets HBM ESD specifications per JEDEC JESD22-A114 (≥2kV), though external TVS devices are still recommended for high-energy transients in industrial environments.
Is the TSSOP-14 package of M74HC132YTTR RoHS compliant and lead-free?
Yes - the M74HC132YTTR (TTR suffix) is manufactured in a RoHS-compliant, lead-free process per EU Directive 2011/65/EU and STMicroelectronics' qualified green packaging standards. The device carries the "RoHS" marking on reel labels and conforms to JEDEC J-STD-020 moisture sensitivity level MSL3 (260°C peak reflow).
