STMicroelectronics M74HC132YRM13TR

Overview

M74HC132YRM13TR from STMicroelectronics is a high-speed CMOS quad 2-input Schmitt-trigger NAND gate in TSSOP-14 package, operating from 2V to 6V supply, with typical propagation delay of 11ns at 6V, ±4mA output drive, and input hysteresis of ~1.2V at 5V - used for noise-immune signal conditioning in digital interface circuits.

For engineers reviewing the M74HC132YRM13TR datasheet, M74HC132YRM13TR pinout, M74HC132YRM13TR application, or M74HC132YRM13TR equivalent, key selection criteria include hysteresis voltage (VP/VN), symmetrical output drive (IOH/IOL), propagation delay matching (tPLH ≅ tPHL), wide VCC range (2–6V), and TSSOP-14 thermal derating (−6.1mW/°C).

Technical Context

This device implements four independent Schmitt-trigger NAND gates using silicon gate C2MOS technology, each with hysteresis (~20% VCC) enabling clean edge regeneration from slow or noisy inputs. Input protection diodes and ESD-hardened structure support robust operation in industrial environments.

All gates feature symmetrical output impedance (|IOH| = IOL ≥ 4mA), balanced propagation delays (tPLH ≅ tPHL), and rail-to-rail output swing (VOH ≥ 5.9V, VOL ≤ 0.26V at VCC = 6V, IO = −5.2mA/+4.0mA), ensuring predictable timing in mixed-signal interface stages.

FAQ

What is the maximum operating temperature for M74HC132YRM13TR?

The device is fully specified from −55°C to +125°C ambient temperature. Absolute maximum junction temperature is 150°C, and thermal derating for the TSSOP-14 package begins at 65°C at −6.1mW/°C. Operation beyond 125°C ambient is not guaranteed per datasheet limits.

Can M74HC132YRM13TR operate reliably at 3.3V supply?

Yes - it is fully functional across 2V to 6V. At VCC = 3.3V, typical propagation delay is ~18ns (−55 to 125°C), VOH ≥ 3.18V, VOL ≤ 0.33V (IOL = 4mA), and hysteresis remains ~0.66V, making it suitable for mixed-voltage 3.3V/5V system interfacing.

Is M74HC132YRM13TR pin-compatible with standard 74HC132 variants?

Yes - pinout and logic function match the industry-standard 74HC132, including identical terminal numbering (1A–4A, 1B–4B, 1Y–4Y, GND, VCC). The 'YRM13TR' suffix denotes TSSOP-14 packaging with tape-and-reel delivery; no functional or pinout deviation exists.

Does this device require external pull-up or pull-down resistors on unused inputs?

No - unused inputs must be tied HIGH or LOW (not left floating), but no external resistors are needed due to internal protection diodes and defined logic thresholds. Connecting directly to VCC or GND ensures stable state and avoids increased ICC or undefined output behavior.
