STMicroelectronics HCF40106YM013TR

Overview

HCF40106YM013TR from STMicroelectronics is an automotive-grade hex Schmitt trigger IC in SO-14 package, providing six independent inverting Schmitt buffers with hysteresis of 0.9 V (at 5 V), 2.3 V (at 10 V), and 3.5 V (at 15 V), enabling robust noise immunity (>50%) and stable waveform shaping in automotive sensor interface and industrial timing circuits.

For engineers reviewing the HCF40106YM013TR datasheet, HCF40106YM013TR pinout, HCF40106YM013TR application, or HCF40106YM013TR equivalent, key selection criteria include hysteresis voltage vs. supply voltage, input leakage current (≤100 nA at 18 V), propagation delay (60–280 ns), output drive capability (±0.36–3.2 mA), and AEC-Q100 qualification for automotive use.

Technical Context

The HCF40106YM013TR implements six independent CMOS Schmitt-trigger inverters, each switching at distinct positive (VP) and negative (VN) thresholds to generate hysteresis (VH = VP − VN). Its input protection network supports ESD resilience (HBM: 2 kV, MM: 200 V, CDM: 1 kV) and operates across 3–20 V supply range.

It delivers symmetrical output characteristics with VOH ≥ 4.95 V and VOL ≤ 0.05 V at VDD = 5 V, and maintains quiescent current as low as 0.02 µA (typ.) at 5 V while supporting full temperature operation from −40 °C to +125 °C per AEC-Q100 Grade 1 requirements.

FAQ

Is HCF40106YM013TR pin-compatible with standard HCF40106 variants?

Yes - HCF40106YM013TR uses the same SO-14 footprint and pinout as non-automotive HCF40106M013TR and HCF40106BE. All six inputs (pins 1,3,5,9,11,13), outputs (2,4,6,8,10,12), VSS (7), and VDD (14) match exactly. The 'Y' suffix denotes AEC-Q100 qualification, not pinout change.

What is the minimum supply voltage for guaranteed Schmitt operation?

The device is specified for reliable Schmitt-trigger operation down to 3 V per Table 5 (Recommended Operating Conditions). At 3 V, VP is typically 1.3 V and VN is 0.4 V (VH ≈ 0.9 V), maintaining >50% noise margin. Below 3 V, hysteresis collapses and behavior becomes undefined.

Can HCF40106YM013TR drive a 10 kΩ load directly?

Yes - with VDD = 5 V, the output can source/sink ≥0.36 mA (min.) while maintaining VOH ≥ 4.95 V and VOL ≤ 0.05 V. A 10 kΩ load draws only 0.5 mA at 5 V, well within the guaranteed IOL/IOH spec, ensuring rail-aligned logic levels without external buffering.

Does this part support 20 V continuous operation?

No - while the Absolute Maximum Rating allows VDD up to +22 V, the Recommended Operating Conditions specify 3–20 V, and electrical characteristics (e.g., VIH/VIL, propagation delay, drive strength) are only guaranteed up to 20 V. Continuous operation at 20 V is permissible but requires validation of thermal dissipation and long-term reliability in the target application.
