Product details
Overview
M74HC132RM13TR 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 symmetrical output drive (±4mA). It enables clean digital signal conditioning in noisy industrial sensor interfaces.
For engineers reviewing the M74HC132RM13TR datasheet, M74HC132RM13TR pinout, M74HC132RM13TR application, or M74HC132RM13TR equivalent, key selection criteria include input hysteresis width (0.6–1.4V), rail-to-rail input voltage range (0 to VCC), guaranteed 4mA output drive at 4.5V, and -55°C to +125°C operating temperature support.
Technical Context
The M74HC132RM13TR implements four independent Schmitt-trigger NAND gates using silicon-gate C2MOS technology, each with ~20% VCC hysteresis (e.g., 0.9V VH at 5V). Input thresholds are specified across voltage and temperature: VP = 2.3–3.15V and VN = 1.13–2.0V at 4.5V, enabling robust noise rejection for slow-rising signals.
It features symmetrical output impedance (|IOH| = IOL ≥ 4mA), balanced tPLH/tPHL propagation delays (≤27ns max at 6V), and low quiescent ICC ≤ 1µA at 25°C. All inputs include ESD and transient overvoltage protection circuits per absolute maximum ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2V to 6V - supports direct interface with 3.3V and 5V logic systems without level shifters |
| Propagation Delay (tPD) | 11ns (typ.) at VCC = 6V - enables reliable operation up to ~30MHz toggle frequency in buffered paths |
| Hysteresis Voltage (VH) | 1.2V (typ.) at VCC = 4.5V - rejects noise spikes <1.2V amplitude on slow analog-like inputs |
| Output Drive Current | ±4mA (min.) at VCC = 4.5V - sufficient to drive multiple 74HC inputs or small LED loads via series resistor |
| Input Leakage Current | ±0.1µA (max.) at TA = 25°C - negligible loading on high-impedance sensor outputs or RC timing networks |
| Operating Temperature | -55°C to +125°C - qualified for under-hood automotive, industrial PLC, and outdoor embedded control |
| Input Capacitance | 5pF (typ.) - minimizes signal distortion on long PCB traces or capacitive touch inputs |
Pinout & Package
TSSOP-14 package: 4.9 × 6.4 mm body, 0.65 mm pitch, 14-pin surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A–4A Inputs | Schmitt-trigger NAND inputs - accept slow-rising signals (e.g., from thermistors or mechanical switches) without oscillation |
| 2, 5, 10, 13 | 1B–4B Inputs | Second input per gate - enables standard NAND logic function with hysteresis on both inputs |
| 3, 6, 8, 11 | 1Y–4Y Outputs | Push-pull CMOS outputs - provide rail-to-rail swing and drive capability into 50pF load |
| 7 | GND | Digital ground reference - must be connected to system ground plane for stable threshold behavior |
| 14 | VCC | Positive supply - decoupling capacitor (100nF) required within 5mm for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Quad Schmitt-trigger NAND gates | Four independent gates with identical hysteresis - eliminates need for external RC debouncing in switch interfaces |
| Rail-to-rail input voltage range | 0V to VCC - accepts analog sensor outputs directly without clamping diodes or biasing |
| Low power consumption | ICC ≤ 1µA (max.) at 25°C - suitable for battery-backed monitoring nodes with multi-year runtime |
| ESD and transient protection | ±20mA input diode current rating - withstands common-mode transients in industrial I/O modules |
| Pin-compatible with 74HC00 | Same pinout as standard quad NAND - allows drop-in replacement where Schmitt input behavior is needed |
Applications
| Industrial Switch Debouncing | Motor Control Feedback Conditioning |
|---|---|
Use Scenario: Mechanical limit switches and emergency stop buttons generate contact bounce and EMI in factory automation panels. IC Role / Device Role / Timing Role: Schmitt NAND gate acts as hardware debouncer and noise filter before PLC input sampling. Use Value: Eliminates software debounce overhead and prevents false triggers from sub-100ns noise spikes due to 1.2V hysteresis margin. | Use Scenario: Hall-effect or optical encoder signals feeding motor commutation logic exhibit slow edges and EMI in high-current environments. IC Role / Device Role / Timing Role: Signal conditioner converting noisy encoder A/B quadrature waveforms into clean, jitter-free logic levels. Use Value: Ensures accurate edge detection for 6-step BLDC commutation by rejecting >1.2V noise while preserving 11ns timing integrity. |
| Temperature Sensor Interface | Power Sequencing Monitor |
Use Scenario: NTC thermistor voltage dividers produce slowly varying analog voltages that must trigger digital thresholds at defined temperatures. IC Role / Device Role / Timing Role: Threshold comparator with built-in hysteresis replacing op-amp + resistor network. Use Value: Reduces BOM count by 3 components per channel and avoids thermal drift issues of discrete comparators. | Use Scenario: Power supply rails (e.g., 12V, 5V, 3.3V) must power up/down in strict sequence to prevent latch-up in FPGAs or microcontrollers. IC Role / Device Role / Timing Role: Glue logic element combining multiple enable signals with hysteresis to avoid metastability during rail transitions. Use Value: Guarantees monotonic state transitions even with 100ms ramp times, preventing false resets during brown-out recovery. |
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; slightly higher ICC (2µA max); identical hysteresis specs | Larger footprint; less suitable for space-constrained PCBs but easier hand-soldering | Select when board real estate permits and manual assembly is required |
| 74LVC132PW | Lower VCC range (1.65–5.5V); higher speed (tPD = 6.3ns typ. at 3.3V); no -55°C rating | Not rated for extended temperature; optimized for portable 3.3V systems only | Select only for commercial-grade 3.3V designs requiring sub-10ns delay |
Compared with SN74HC132DR and 74LVC132PW, the M74HC132RM13TR uniquely combines TSSOP-14 compactness, full -55°C to +125°C qualification, and ultra-low 1µA ICC - making it optimal for ruggedized industrial and automotive subsystems where size, temperature, and power co-constrain design.

FAQ
What is the minimum supply voltage for guaranteed Schmitt-trigger operation?
The M74HC132RM13TR guarantees correct Schmitt behavior down to VCC = 2.0V, with specified hysteresis (VH = 0.3–1.0V) and threshold voltages (VP/VN) fully characterized across this range. Below 2.0V, functionality is not assured per datasheet limits.
Can this device drive a 50pF load at 10MHz without signal degradation?
Yes - AC specifications confirm tPLH/tPHL ≤27ns (max) and output transition time ≤19ns (at 6V, CL = 50pF), supporting clean 10MHz square waves. Measured VOH/VOL remain within spec under 4mA load, ensuring adequate noise margin at that frequency.
Is the TSSOP-14 package compatible with standard reflow profiles?
Yes - the M74HC132RM13TR uses JEDEC-standard Pb-free TSSOP packaging, qualified for IPC/JEDEC J-STD-020D reflow profiles with peak temperature ≤260°C and 60-second exposure above 217°C, matching common lead-free assembly lines.
How does input hysteresis improve performance with mechanical switch inputs?
With ~1.2V hysteresis at 4.5V supply, the device requires input voltage to cross two distinct thresholds (e.g., 2.3V to switch high, then fall below 1.1V to switch low), eliminating chatter from microsecond-scale contact bounce and EMI-induced glitches without software or RC filtering.
