Product details
Overview
74HC132DB,112 from Nexperia is a quad 2-input NAND gate with Schmitt-trigger inputs, designed for noise-immune signal conditioning in digital timing and waveform shaping circuits. It operates from 2.0 V to 6.0 V, delivers hysteresis of 0.6–1.6 V (VCC = 2.0–6.0 V), supports −40 °C to +125 °C ambient range, and exhibits propagation delay as low as 10 ns at VCC = 6.0 V - used in relaxation oscillators and pulse edge sharpening.
For engineers reviewing the 74HC132DB,112 datasheet, 74HC132DB,112 pinout, 74HC132DB,112 application, or 74HC132DB,112 equivalent, this device serves as a robust input conditioner where slow-rising signals, EMI-prone environments, or stable multivibrator timing are critical - especially when interfacing sensors, mechanical switches, or RC networks to CMOS logic.
Technical Context
The 74HC132DB,112 implements four independent Schmitt-trigger NAND gates, each with asymmetric input thresholds (VT+ and VT−) enabling clean output transitions from noisy or slowly varying inputs. Its clamped inputs accept voltages beyond VCC when current-limited, supporting direct interface to higher-voltage sources without level shifters.
It complies with JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V), features HBM ESD >2000 V and CDM >1000 V, and maintains latch-up immunity exceeding 100 mA per JESD78 Class II Level B - confirming suitability for industrial control and embedded sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct operation from 3.3 V or 5 V rails without regulation. |
| Propagation Delay (tpd) | 10 ns (max) at VCC = 6.0 V - ensures sub-100 MHz timing stability in oscillator and monostable designs. |
| Hysteresis Voltage (VH) | 0.6 V to 1.6 V - rejects noise up to ±0.8 V on input signals, preventing false triggering. |
| Input Thresholds (VT+, VT−) | VT+ = 2.1–4.2 V, VT− = 1.2–3.0 V at VCC = 6.0 V - defines precise switching windows for reliable waveform regeneration. |
| Output Drive Capability | ±25 mA - sufficient to directly drive LEDs, small capacitive loads, or subsequent CMOS inputs. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor controllers. |
| Power Dissipation (Ptot) | 500 mW (SO14 package) - supports continuous operation in compact PCB layouts with minimal thermal derating below 100 °C. |
Pinout & Package
74HC132DB,112 is packaged in SO14 (SOT108-1): plastic small outline, 14-lead, 3.9 mm body width, with gull-wing leads and pin 1 index marker.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A | Data Input A | First input of each NAND gate; Schmitt-triggered for noise rejection. |
| 1B, 2B, 3B, 4B | Data Input B | Second input of each NAND gate; independently thresholded with hysteresis. |
| 1Y, 2Y, 3Y, 4Y | Data Output | Active-low NAND output; drives CMOS/TTL loads with rail-to-rail swing. |
| GND (Pin 7) | Ground Reference | 0 V return path for all internal logic and I/O; must be low-impedance. |
| VCC (Pin 14) | Supply Voltage | Primary power rail; decoupling capacitor required within 10 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Unlimited Input Rise/Fall Times | Enables reliable operation with RC-generated edges or mechanical switch bounce - no minimum slew rate required. |
| Clamp Diodes on Inputs | Permits safe interfacing to voltages > VCC using external current-limiting resistors, eliminating need for discrete protection. |
| High Noise Immunity | Typical hysteresis ≥0.8 V at 5 V supply ensures rejection of common-mode spikes up to 1.2 Vpp. |
| Wide Temperature Range | Specified from −40 °C to +125 °C - validated for use in engine control units and outdoor IoT nodes. |
| Low Static Current | ICC ≤ 40 μA at VCC = 6.0 V and T = +125 °C - minimizes quiescent power in battery-backed systems. |
Applications
| Waveform Shaping | Astable Multivibrator |
|---|---|
Use Scenario: Converting slow-rising analog sensor outputs (e.g., thermistor voltage ramps) into clean digital pulses for microcontroller capture. IC Role / Device Role / Timing Role: Input signal conditioner and edge regenerator - transforms analog transitions into jitter-free square waves. Use Value: Eliminates multiple external comparators and hysteresis resistors; reduces BOM count by 3–4 components per channel. | Use Scenario: Generating fixed-frequency clock signals in LED flashers or status indicators using only two gates and an RC network. IC Role / Device Role / Timing Role: Core timing element in cross-coupled feedback configuration - sets oscillation frequency via R and C values. Use Value: Achieves <±5% frequency stability over temperature without crystals or trimmers; supports 10 kHz–1 MHz range. |
| Monostable Multivibrator | Pulse Edge Detection |
Use Scenario: Creating precise one-shot delays for debouncing push-button inputs or synchronizing asynchronous events in PLC I/O modules. IC Role / Device Role / Timing Role: Triggered delay generator - converts momentary contact closure into fixed-duration logic pulse. Use Value: Provides adjustable delay (10 μs–100 ms) with single external RC; avoids software polling or timer resource allocation. | Use Scenario: Detecting rising/falling edges of irregular waveforms (e.g., encoder quadrature signals or motor commutation pulses). IC Role / Device Role / Timing Role: Differential edge detector - uses Schmitt thresholds to isolate transitions amid high-frequency noise. Use Value: Rejects glitches <100 ns wide; delivers clean strobes to interrupt controllers without firmware filtering overhead. |
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 |
|---|---|---|---|
| 74HCT132DB,112 | TTL-compatible input thresholds (VT+ ≈ 1.4 V, VT− ≈ 0.6 V at VCC = 5 V); identical pinout and output drive. | Better suited for mixed 5 V TTL/CMOS systems; less tolerant of slow edges below 1 V/ns slew rate. | Select when interfacing legacy 5 V TTL logic or when tighter input threshold symmetry is needed. |
| SN74LV132APWR | Lower VCC range (1.65–5.5 V); reduced hysteresis (0.3–0.8 V); 3.3 V optimized; same SO14 footprint. | Preferred for low-voltage portable devices; not rated for 6 V operation or −40 °C to +125 °C extended range. | Choose for battery-powered applications requiring <1.8 V compatibility and lower dynamic power. |

FAQ
What is the maximum recommended supply voltage for 74HC132DB,112?
The absolute maximum supply voltage is +7.0 V, but the recommended operating range is 2.0 V to 6.0 V per datasheet Table 5. Operation above 6.0 V risks permanent damage and violates JEDEC JESD7A compliance - sustained use at 6.5 V is not guaranteed and may accelerate parametric drift.
Can 74HC132DB,112 drive a 50 pF load at 10 MHz without signal degradation?
Yes: at VCC = 5.0 V and CL = 50 pF, typical propagation delay is 11 ns and transition time is ≤13 ns (Table 7), yielding usable bandwidth >30 MHz. Output rise/fall times remain monotonic with no overshoot, confirmed by Fig. 4 waveforms and test circuit in Fig. 5.
Is the GND pad on the SO14 package required to be soldered?
No - the exposed thermal pad (if present in variant) is not electrically connected and has no grounding requirement. For standard SO14 (SOT108-1), there is no thermal pad; pins 1–14 are sole terminations. Soldering is only required for the 14 gull-wing leads per IPC-7095 guidelines.
Does 74HC132DB,112 support mixed-voltage interfacing (e.g., 3.3 V MCU to 5 V peripheral)?
Yes - its Schmitt-trigger inputs accept VI up to VCC + 0.5 V (Table 4), and clamp diodes allow safe interface to voltages > VCC when series current-limiting resistors are used. For 3.3 V MCU driving 5 V-powered 74HC132DB,112, no level shifter is needed if MCU outputs meet VOH ≥ 3.5 V.
