Product details
Overview
MC74HC132AFELG 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 across 2.0–6.0 V, delivers 10 LSTTL loads, features hysteresis up to 3.0 V at 6.0 V supply, and is housed in a TSSOP-14 package. It is used in debouncing mechanical switches and cleaning slow-rising waveforms in industrial control I/O stages.
For engineers reviewing the MC74HC132AFELG datasheet, pinout, applications, or equivalent options, key selection criteria include input hysteresis voltage (0.2–3.0 V), propagation delay (21–190 ns), operating voltage range (2.0–6.0 V), output drive capability (10 LSTTL loads), and TSSOP-14 thermal resistance (150 °C/W).
Technical Context
The MC74HC132AFELG implements four independent Schmitt-trigger NAND gates using high-performance silicon-gate CMOS technology. Each gate exhibits asymmetric input thresholds (VT+min = 0.95 V, VT−max = 2.65 V at VCC = 6.0 V), yielding programmable hysteresis (VHmin = 0.2 V, VHmax = 3.0 V) to reject noise on slow or noisy signals.
It is pin-compatible with LS132 and supports mixed-voltage interfacing: inputs accept standard CMOS outputs directly and-when pulled up-LSTTL outputs. Its quiescent ICC is ≤10 µA at 6.0 V, and it meets JEDEC Std. No. 7A for CMOS compatibility.
Key Specifications

|---|---|
|
Use Scenario: Mechanical pushbuttons and limit switches generate contact bounce lasting 1–10 ms in PLC I/O modules.

| Automotive Sensor Interface | Legacy TTL Signal Conditioning |
|
Use Scenario: Hall-effect or reed-switch position sensors output low-slew signals in engine control units exposed to EMI.

Use Scenario: Integrating modern HC logic into legacy 5 V TTL systems with marginal noise margins. IC Role / Device Role / Timing Role: MC74HC132AFELG bridges voltage domains - inputs tolerate LSTTL levels with pull-up resistors; outputs drive TTL loads directly. Use Value: Enables drop-in replacement of 74LS132 without redesigning power or interface circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad Schmitt-trigger NAND applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC132DR | SOIC-14 package (larger footprint, higher θJA = 116 °C/W); identical electrical specs and pinout | Preferred for prototyping or high-reliability through-hole assembly; less suitable for space-constrained PCBs | Select SN74HC132DR if board layout allows SOIC-14 and thermal derating above 75 °C is not required. |
| MC74HCT132ADTR2G | TTL-compatible inputs (4.5–5.5 V only); same TSSOP-14 package and pinout; lower hysteresis (0.4 V typ) | Better suited for pure 5 V TTL systems where input noise is minimal and level matching is critical | Choose MC74HCT132ADTR2G only when interfacing exclusively with TTL outputs and supply is fixed at 5.0 V ±10%. |
Compared with SN74HC132DR and MC74HCT132ADTR2G, the MC74HC132AFELG offers the widest supply range (2.0–6.0 V) and highest hysteresis (3.0 V max), making it optimal for mixed-voltage, noise-prone, or battery-operated designs where flexibility and robustness are prioritized over strict TTL compatibility.

FAQ
What is the maximum supply voltage for MC74HC132AFELG?
The absolute maximum DC supply voltage (VCC) for MC74HC132AFELG is +6.5 V, but the recommended operating range is 2.0 V to 6.0 V. Operation above 6.0 V risks exceeding internal oxide breakdown limits and is not guaranteed for reliability or parametric performance. The MC74HC132AFELG achieves optimal hysteresis and propagation delay within the 2.0–6.0 V window.
Does MC74HC132AFELG support direct connection to LSTTL outputs?
Yes, MC74HC132AFELG inputs are compatible with standard CMOS outputs and - when pulled up with external resistors - with LSTTL outputs. This dual compatibility is confirmed in the datasheet's "Features" section and enables seamless integration into mixed-logic systems without level translators. The MC74HC132AFELG does not require external biasing for CMOS drivers but benefits from 10 kΩ pull-ups when driven by LSTTL.
What is the typical hysteresis voltage of MC74HC132AFELG at 5.0 V supply?
At VCC = 5.0 V, the typical hysteresis voltage (VH) of MC74HC132AFELG is 1.5 V, calculated as the difference between typical VT+ (3.15 V) and VT− (1.65 V) values per the DC Electrical Characteristics table. This value ensures robust noise rejection for signals with amplitude variations up to ±750 mV around the switching threshold, which is critical in motor control feedback paths.
Is MC74HC132AFELG pin-compatible with the 74LS132?
Yes, MC74HC132AFELG is explicitly stated in the datasheet to be identical in pinout to the 74LS132. All 14 pins - including VCC (14), GND (7), and the four A/B/Y signal groups - match exactly. This allows direct PCB replacement in legacy designs, provided supply voltage and loading conditions fall within the HC family's operating range.
What package type is used for MC74HC132AFELG?
MC74HC132AFELG uses the TSSOP-14 package (Case 948G), measuring 4.9 mm × 4.4 mm × 1.2 mm with 0.65 mm lead pitch. It is Pb-free, RoHS-compliant, and rated MSL Level 1 - meaning it can be stored indefinitely at ambient conditions without baking prior to reflow soldering. This package enables high-density routing in compact industrial controllers.
