Product details
Overview
MC74HCT132ADG from onsemi is a quad 2-input NAND gate with Schmitt-trigger inputs, designed for noise-immune signal conditioning in digital logic interfaces. It operates from 2.0 V to 6.0 V, delivers ±4 mA output drive at 5 V, exhibits 0.4 V typical hysteresis, and is pin-compatible with LS132 for legacy TTL system upgrades in industrial control panels.
For engineers reviewing the MC74HCT132ADG datasheet, pinout, applications, or equivalent options, key selection criteria include input hysteresis voltage (0.4 V min), propagation delay (25 ns max at 5 V), LSTTL-compatible input thresholds, and SOIC-14 package compatibility with existing through-hole or surface-mount board layouts.
Technical Context
The MC74HCT132ADG implements four independent Schmitt-trigger NAND gates using high-performance silicon-gate CMOS technology. Each gate features asymmetric input thresholds (VT+min = 1.2 V, VT−max = 1.4 V at VCC = 4.5–5.5 V) to deliver 0.4 V minimum hysteresis, enabling reliable squaring of slow-rising signals and rejection of high-frequency noise on input lines.
It supports mixed-voltage interfacing: inputs accept standard CMOS levels natively and-when pulled up-LSTTL outputs; outputs directly drive CMOS, NMOS, and TTL loads (up to 10 LSTTL units). The device is rated for operation from −55 °C to +125 °C and complies with JEDEC Std. 7A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct interface with 3.3 V and 5 V logic domains without level shifters |
| Hysteresis Voltage (VHmin) | 0.4 V min - ensures ≥400 mV noise margin against spurious switching on noisy PCB traces |
| Propagation Delay (tPLH/tPHL) | 25 ns max at VCC = 5.0 V, TA = −55 °C to +25 °C - supports ≤20 MHz clock/data edge rates in timing-critical paths |
| Output Drive (IOH/IOL) | ±4.0 mA at VCC = 4.5 V - sufficient to drive 10 LSTTL loads or fan out to multiple CMOS inputs |
| Input Leakage Current (IIN) | 1.0 µA max at VCC = 5.5 V - minimizes power loss in battery-backed or low-quiescent systems |
| Operating Temperature | −55 °C to +125 °C - qualified for under-hood automotive, industrial motor control, and outdoor equipment |
Pinout & Package
MC74HCT132ADG is housed in a Pb-free SOIC-14 (Case 751A) package with standard 1.27 mm pitch, 8.75 mm × 3.9 mm body, and gull-wing leads. Pin 1 is marked by a notch or beveled corner; pin 14 is VCC, pin 7 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 11, 12 | NAND Input (A1/B1, A2/B2, A3/B3, A4/B4) | Schmitt-triggered logic inputs - tolerate slow edges and reject noise spikes < 0.4 V amplitude |
| 3, 6, 10, 13 | NAND Output (Y1/Y2/Y3/Y4) | CMOS-compatible push-pull outputs - sink/source ±4 mA, rail-to-rail swing |
| 7 | GND | Ground reference for all inputs/outputs and internal circuitry - must be low-impedance connection |
| 14 | VCC | Positive supply rail - bypassing with 0.1 µF ceramic capacitor near pin required for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| LSTTL-Compatible Inputs (with pull-up) | Enables drop-in replacement of LS132 in legacy 5 V systems without redesigning input bias networks |
| 0.4 V Minimum Hysteresis | Guarantees clean, bounce-free output transitions even with >1 µs input rise/fall times or >100 mV EMI coupling |
| 10 LSTTL Load Drive Capability | Supports direct fan-out to multiple downstream TTL devices without buffer amplification |
| JEDEC Std. 7A Compliance | Meets industry-standard DC and AC electrical requirements for interoperability across logic families |
Applications
| Industrial Sensor Interface | Automotive Body Control |
|---|---|
Use Scenario: Conditioning analog sensor outputs (e.g., thermistor divider, potentiometer wiper) before feeding into microcontroller ADC or GPIO. IC Role / Device Role / Timing Role: Signal squaring and noise filtering stage - converts slow, noisy analog thresholds into clean digital edges. Use Value: Eliminates need for external RC filters or comparator ICs; reduces BOM count and layout area while improving EMC robustness. | Use Scenario: Debouncing mechanical switch inputs (door latch, trunk release, seat position) in vehicle body control modules. IC Role / Device Role / Timing Role: Digital input conditioner - suppresses contact bounce and conducted transients before MCU interrupt detection. Use Value: Prevents false triggers during vibration or ESD events; meets ISO 11452-4 immunity requirements without added ferrites or TVS diodes. |
| Legacy System Upgrade | Power Sequencing Monitor |
Use Scenario: Replacing obsolete 74LS132 in industrial PLC I/O cards requiring extended temperature range and lower power. IC Role / Device Role / Timing Role: Pin-compatible logic upgrade component - retains same PCB footprint and netlist connectivity.

IC Role / Device Role / Timing Role: Timing window detector - uses Schmitt-trigger hysteresis to avoid metastability during rail ramp-up. Use Value: Ensures deterministic power-on reset assertion with no external timing capacitors or precision references needed. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate with Schmitt-trigger input applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT132DR | Same logic function, hysteresis, and DC specs; TSSOP-14 package (4.4 mm × 5.0 mm), not SOIC-14 | Requires PCB layout change due to different footprint and thermal pad; better for space-constrained designs | Select when board area is limited and reflow profile supports fine-pitch TSSOP |
| 74HCT132D,653 | Identical SOIC-14 package and pinout; manufactured by Nexperia, JEDEC-compliant but no AEC-Q100 qualification | Lacks automotive qualification; suitable for commercial/industrial use only | Select for cost-sensitive non-automotive applications where AEC-Q100 is not required |
Compared with SN74HCT132DR and 74HCT132D,653, the MC74HCT132ADG offers verified AEC-Q100 qualification and onsemi's long-term industrial support, making it preferred for automotive body electronics and mission-critical industrial controls where supply continuity and stress-tested reliability are mandatory.

FAQ
What is the maximum operating temperature for MC74HCT132ADG?
The MC74HCT132ADG is rated for operation from −55 °C to +125 °C. This full industrial temperature range is validated per JEDEC standards and supported by onsemi's qualification testing, making MC74HCT132ADG suitable for under-hood automotive applications and high-ambient industrial enclosures where thermal derating is critical.
Does MC74HCT132ADG require external pull-up resistors on inputs?
MC74HCT132ADG inputs are compatible with standard CMOS outputs without pull-ups. However, when interfacing with LSTTL outputs, external pull-up resistors (typically 1–10 kΩ to VCC) are required to ensure valid high-level input voltage - because LSTTL VOH (2.4 V min) falls below the MC74HCT132ADG VT+min (1.2 V min) but may not guarantee reliable logic high without biasing.
Can MC74HCT132ADG be used as a standalone oscillator?
No, MC74HCT132ADG is not designed or characterized for oscillator operation. While Schmitt-trigger gates can form relaxation oscillators with external RC networks, the MC74HCT132ADG datasheet does not specify startup time, frequency stability, or phase noise - and its internal design prioritizes noise immunity over timing precision. Use dedicated oscillator ICs or crystal-based solutions for clock generation.
Is MC74HCT132ADG pin-compatible with the original 74LS132?
Yes, MC74HCT132ADG is explicitly stated in the datasheet to be identical in pinout to the 74LS132. All 14 pins map functionally and physically: inputs A1–B4, outputs Y1–Y4, VCC (pin 14), and GND (pin 7) align exactly - enabling direct socket replacement or PCB-level drop-in upgrades in legacy 5 V TTL systems.
What is the typical power dissipation of MC74HCT132ADG at 5 V?
At VCC = 5.0 V and 25 °C, the typical power dissipation per gate is calculated using CPD = 24 pF: PD = CPD × VCC² × f + ICC × VCC. With no switching (f = 0), quiescent ICC is ≤10 µA, yielding ~50 µW. At 1 MHz toggle rate, dynamic contribution dominates - approximately 0.6 mW per gate, or ~2.4 mW total for all four gates, well within the SOIC-14 package's 500 mW rating.
