Product details
Overview
74HCT132D,652 from Nexperia is a quad 2-input NAND gate with Schmitt-trigger inputs in SO14 (SOT108-1) package, operating from 4.5 V to 5.5 V supply, delivering hysteresis of 0.4–0.6 V and propagation delay as low as 20 ns at 4.5 V - used for noise-immune waveform shaping in industrial timing circuits.
For engineers reviewing the 74HCT132D,652 datasheet, 74HCT132D,652 pinout, 74HCT132D,652 application, or 74HCT132D,652 equivalent, this page delivers verified functional identity, validated SO14 pin mapping, confirmed Schmitt-trigger transfer characteristics, and real-world multivibrator design context - no generic timing assumptions.
Technical Context
The device implements four independent NAND gates, each with asymmetric Schmitt-trigger input thresholds (VT+ = 1.2–1.9 V, VT− = 0.5–1.4 V at VCC = 4.5–5.5 V), enabling reliable signal conditioning of slow-rising or noisy digital edges. Input clamp diodes allow safe interfacing to voltages exceeding VCC when current-limited.
It operates across −40 °C to +125 °C, complies with JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V), and features ESD protection exceeding 2000 V HBM and 1000 V CDM - critical for industrial control I/O stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND with Schmitt-trigger inputs - enables noise rejection on both inputs per gate |
| Supply Voltage Range | 4.5 V to 5.5 V - TTL-compatible operation, avoids level-shifting in 5 V systems |
| Hysteresis Voltage (VH) | 0.4 V to 0.6 V - ensures ≥400 mV noise margin against false triggering on slow edges |
| Propagation Delay (tpd) | 20 ns typical at VCC = 4.5 V, CL = 50 pF - supports ≤25 MHz relaxation oscillator designs |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple 74-series inputs or small capacitive loads |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood or industrial motor-control ambient conditions |
| Input Clamp Diodes | Integrated - permits direct interface to signals up to VCC + 0.5 V with external current limiting |
Pinout & Package
74HCT132D,652 uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A | Data input A per gate | First Schmitt-trigger input of each NAND gate; accepts slow-rising signals without chatter |

| 1Y, 2Y, 3Y, 4Y | Data output per gate | Active-low NAND output; drives downstream logic or RC timing networks directly |
| 7 | GND | Ground reference (0 V); mandatory return path for all internal currents and output sinks |
| 14 | VCC | Positive supply (4.5–5.5 V); powers all four gates and defines logic threshold references |
Key Features
| Feature | Design Value |
|---|---|
| Unlimited input rise/fall times | Enables use with RC-generated edges in astable/monostable multivibrators without timing distortion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger NAND applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC132D,652 | CMOS version: wider 2.0–6.0 V supply range; higher VIH/VIL thresholds at low VCC | Better for mixed-voltage systems (e.g., 3.3 V logic driving 5 V peripherals) | Select when supply voltage may drop below 4.5 V or when interfacing with HC-family devices |
| SN74LV132APWR | TI LV family: 2.0–5.5 V supply; lower ICC (1 μA typ), faster tpd (11 ns @ 3.3 V) | Optimized for low-power 3.3 V embedded systems; not rated for 125 °C | Prefer for battery-powered or space-constrained 3.3 V designs where extended temperature is not required |
Compared with 74HC132D,652 and SN74LV132APWR, the 74HCT132D,652 offers superior noise margin at 5 V, guaranteed 125 °C operation, and direct TTL-level compatibility - making it the optimal choice for industrial control panels and automotive body electronics where reliability trumps ultra-low power.

FAQ
What is the minimum supply voltage for reliable operation of 74HCT132D,652?
The 74HCT132D,652 is specified for reliable operation from 4.5 V to 5.5 V. Below 4.5 V, input thresholds (VT+ ≈ 1.2 V, VT− ≈ 0.5 V) shift unpredictably, and output drive degrades - it is not guaranteed to function correctly at 3.3 V or lower. For sub-4.5 V systems, consider the 74HC132D,652 instead.
Can 74HCT132D,652 be used as a standalone oscillator without external components?
No - the 74HCT132D,652 requires external resistors and capacitors to form an astable or monostable multivibrator. A minimal relaxation oscillator uses two gates, one resistor, and one capacitor (Fig. 12 in datasheet). It has no internal timing elements and cannot oscillate without those external components.
Does 74HCT132D,652 support hot insertion or live I/O connection?
While input clamp diodes permit limited overvoltage tolerance (up to VCC + 0.5 V with current limiting), the device is not designed for hot-plug operation. No bus-hold, Ioff, or power-off protection is specified. Live connection without pre-charging or current limiting risks latch-up or ESD damage during insertion.
How does hysteresis improve performance in noisy industrial environments?
Hysteresis (0.4–0.6 V) creates distinct high-to-low and low-to-high switching thresholds, preventing multiple output transitions when input voltage lingers near the switching point due to EMI or crosstalk. This eliminates contact bounce artifacts and sensor noise-induced jitter - critical for accurate timing in PLC input modules and motor feedback circuits.
