Product details

Overview

74HC132D/AUJ from Nexperia 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 propagation delay as low as 10 ns at 6.0 V (V_CC), and features hysteresis of 0.6–1.6 V to reject slow-rising or noisy input edges-common in sensor interfacing and oscillator circuits.

For engineers reviewing the 74HC132D/AUJ datasheet, 74HC132D/AUJ pinout, 74HC132D/AUJ application, or 74HC132D/AUJ equivalent, this device is selected for wave shaping, relaxation oscillators, and monostable multivibrator designs where input signal integrity and jitter-free output transitions are critical.

Technical Context

The 74HC132D/AUJ implements four independent Schmitt-trigger NAND gates in a single SO14 package. Each gate transforms analog-like input transitions into clean digital outputs via dual threshold detection (V_T+ and V_T−), enabling reliable operation with rise/fall times up to microseconds without added external hysteresis circuitry.

Its CMOS architecture ensures low static current (≤40 μA over −40 °C to +125 °C), high noise immunity (>1.2 V typical hysteresis at 4.5 V), and compatibility with both 3.3 V and 5 V logic families-while maintaining full rail-to-rail output swing under load.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	2.0 V to 6.0 V - supports direct interface with 3.3 V microcontrollers and legacy 5 V systems without level shifters.
Propagation delay (t_pd)	10 ns (max) at V_CC = 6.0 V, C_L = 50 pF - enables stable operation up to ~30 MHz in oscillator or timing feedback loops.
Hysteresis voltage (V_H)	0.6–1.6 V (depending on V_CC) - rejects noise spikes ≤1.5 V without false triggering in industrial sensor lines.
Input leakage current	±1.0 μA max (−40 °C to +125 °C) - minimizes loading on high-impedance sources like RC networks in astable circuits.
Operating temperature	−40 °C to +125 °C - qualified for under-hood automotive modules and industrial control cabinets without derating.
ESD protection	HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events without latch-up or parametric shift.

Pinout & Package

74HC132D/AUJ uses the SOT108-1 (SO14) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm pitch, JEDEC MS-012 compliant. Pin 1 is index-marked; pin 7 is GND; pin 14 is V_CC.

Pin/Terminal	Circuit Role	Design Meaning
1, 4, 9, 12	Input A (nA)	First input per NAND gate; accepts slow-rising signals due to Schmitt-trigger threshold hysteresis.
2, 5, 10, 13	Input B (nB)	Second input per NAND gate; electrically identical to nA pins; no internal priority or sequencing.
3, 6, 8, 11	Output Y (nY)	Active-low NAND output; drives standard TTL/CMOS loads up to ±25 mA; rail-to-rail swing.
7	GND	Ground reference for all inputs/outputs; must be connected to system 0 V plane for noise immunity.
14	V_CC	Positive supply; decoupling capacitor (100 nF ceramic) required within 5 mm for stable switching.

Key Features

Feature	Design Value
Unlimited input rise/fall times	Enables direct connection to RC networks or mechanical switch debouncing without external timing components.
Schmitt-trigger inputs	Provides 0.6–1.6 V hysteresis to eliminate chatter on noisy or slowly varying signals (e.g., thermistor or potentiometer outputs).
Wide supply range (2.0–6.0 V)	Eliminates need for separate voltage regulators when interfacing mixed-voltage subsystems (e.g., 3.3 V MCU + 5 V sensors).
Latch-up immunity >100 mA	Guarantees robustness against transient overvoltage or ground bounce during hot-plug or power sequencing.
−40 °C to +125 °C operation	Validated for use in automotive engine control units, industrial PLC I/O modules, and outdoor telecom equipment.

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
74HCT132D	CMOS-compatible inputs but TTL-level thresholds (V_T+ ≈ 1.4 V @ 5 V); slightly higher ICC at 5 V.	Better suited for 5 V systems with legacy TTL outputs; less tolerant of sub-3 V logic levels.	Select 74HCT132D when interfacing directly with 74LS-series outputs or when V_CC is fixed at 4.5–5.5 V.
SN74LV132APWR	Lower V_CC range (1.65–5.5 V); faster t_pd (7.5 ns typ @ 3.3 V); smaller TSSOP-14 footprint.	Optimized for battery-powered 3.3 V systems; not rated for 6 V operation or +125 °C ambient.	Choose SN74LV132APWR for portable devices requiring ultra-low power and compact layout, but verify thermal margin.

Compared with 74HC132D/AUJ, 74HCT132D offers tighter input compatibility with older TTL logic but sacrifices 2.0 V operation, while SN74LV132APWR improves speed and efficiency at 3.3 V yet lacks the extended voltage and temperature range needed for harsh-environment designs.

FAQ

What is the maximum supply voltage for the 74HC132D/AUJ?

The absolute maximum supply voltage for the 74HC132D/AUJ is +7.0 V, but the recommended operating range is 2.0 V to 6.0 V per the datasheet. Operation above 6.0 V risks exceeding limiting values and may cause permanent damage or accelerated aging. For reliable long-term function, maintain V_CC ≤ 6.0 V in all conditions, including transients.

Does the 74HC132D/AUJ require external pull-up resistors on its inputs?

No, the 74HC132D/AUJ does not require external pull-up resistors on its inputs because it contains built-in clamp diodes and Schmitt-trigger circuitry that ensures defined logic states even with floating or high-impedance sources. However, pull-ups/downs are still recommended for unused inputs to prevent unintended oscillation or increased ICC.

Can the 74HC132D/AUJ drive a 50 pF load at 10 MHz reliably?

Yes-the 74HC132D/AUJ is characterized with C_L = 50 pF and achieves t_pd ≤ 21 ns at V_CC = 6.0 V, supporting clean toggling at ≥10 MHz. Its output can source/sink ±25 mA, easily driving 50 pF loads with fast edge rates (t_t ≤ 13 ns). Ensure proper V_CC decoupling and minimize trace inductance for stable high-frequency operation.

How does the hysteresis of the 74HC132D/AUJ improve noise immunity?

The 74HC132D/AUJ provides 0.6–1.6 V hysteresis (V_H = V_T+ − V_T−) depending on V_CC, meaning the input must cross two distinct thresholds to toggle output state. This prevents multiple transitions caused by noise riding on slow edges-e.g., a 1.0 V noise spike on a 2.5 V rising edge won't trigger false output changes if V_T− = 1.7 V and V_T+ = 2.7 V.

Is the 74HC132D/AUJ pin-compatible with the 74HC132N or 74HC132PW packages?

No-the 74HC132D/AUJ (SO14/SOT108-1) shares identical pinout and logic function with 74HC132PW (TSSOP14) and 74HC132BQ (DHVQFN14), but physical pin spacing and mounting differ. While electrical behavior is identical, PCB layout must match the specific package: SO14 requires 1.27 mm pitch pads, TSSOP14 needs 0.65 mm pitch, and DHVQFN14 demands land-pattern alignment per SOT762-1.
