Product details
Overview
MC74HCT132ADR2G from onsemi is a quad 2-input NAND gate with Schmitt-trigger inputs, LSTTL-compatible inputs, and high-noise-immunity CMOS logic. It operates from 2.0 V to 6.0 V, delivers 10 LSTTL loads, and features hysteresis ≥0.4 V for reliable waveform squaring in noisy environments - used in industrial sensor interface conditioning and reset signal debouncing.
For engineers reviewing the MC74HCT132ADR2G datasheet, pinout, applications, or equivalent options, key selection criteria include input hysteresis voltage (0.4 V min), propagation delay (38 ns max at 125°C), output drive strength (±4 mA), supply voltage range (2.0–6.0 V), and SOIC-14 Pb-free packaging compatibility.
Technical Context
The MC74HCT132ADR2G implements four independent Schmitt-trigger NAND gates using high-performance silicon-gate CMOS technology. Each gate exhibits asymmetric input thresholds (VT+min = 1.2 V, VT−max = 1.4 V at VCC = 4.5–5.5 V) and guaranteed hysteresis of 0.4 V, enabling robust noise rejection on slow-rising or noisy digital signals.
It maintains LSTTL-compatible input levels when pulled up and directly interfaces with CMOS, NMOS, and TTL loads. Its quiescent ICC is ≤40 µA at 125°C, and it complies with JEDEC Std 7A while supporting −55°C to +125°C operation across SOIC-14 packaging.

FAQ
What is the maximum operating temperature for MC74HCT132ADR2G?
The MC74HCT132ADR2G is rated for continuous operation from −55°C to +125°C. This extended temperature range is validated per JEDEC standards and supports use in under-hood automotive modules, industrial motor drives, and outdoor equipment where ambient thermal stress exceeds commercial-grade limits. The MC74HCT132ADR2G maintains full functionality and parameter compliance across this entire range.
Does MC74HCT132ADR2G require external pull-up resistors for LSTTL compatibility?
Yes - MC74HCT132ADR2G inputs are compatible with LSTTL outputs only when external pull-up resistors are applied. Its CMOS inputs have high impedance and cannot sink sufficient current to meet LSTTL low-level voltage requirements without pull-ups. The MC74HCT132ADR2G datasheet specifies that pull-up resistors ensure proper VIH/VIL thresholds when interfacing with legacy TTL sources.
Can MC74HCT132ADR2G replace the obsolete LS132 in existing designs?
Yes - MC74HCT132ADR2G is explicitly designed as a pinout-identical replacement for the LS132. It matches the SOIC-14 footprint, terminal assignments, and logic function while adding Schmitt-trigger inputs, wider supply range (2.0–6.0 V), and lower power consumption. The MC74HCT132ADR2G requires no PCB changes and maintains full backward compatibility in legacy LS132-based systems.
What is the minimum hysteresis voltage specified for MC74HCT132ADR2G?
The MC74HCT132ADR2G guarantees a minimum hysteresis voltage (VHmin) of 0.4 V across all operating conditions, calculated as VT+min − VT−max. This value is tested at VCC = 4.5 V to 5.5 V and over temperature (−55°C to +125°C). The MC74HCT132ADR2G uses this hysteresis to reject noise up to ±200 mV on input signals without false triggering.
Is MC74HCT132ADR2G compliant with automotive qualification standards?
Yes - the MC74HCT132ADR2G is AEC-Q100 qualified and PPAP capable. It meets Grade 1 temperature requirements (−40°C to +125°C) and includes enhanced process controls for automotive applications. While the base part operates from −55°C to +125°C, its AEC-Q100 qualification confirms reliability for passenger compartment and engine bay deployments. The MC74HCT132ADR2G carries the NLV prefix variant for full automotive traceability.
