Texas Instruments CMOS Hex Schmitt Trigger Inverter SOIC 14-Pin 40106

Texas Instruments CMOS Hex Schmitt Trigger Inverter provides six independent Schmitt-trigger inverter circuits in a compact 14-pin SOIC package, with a supply voltage range of 3 V to 18 V.

Each circuit operates as an inverter with Schmitt-trigger action on its input, switching at different voltage points for positive-going (VP) and negative-going (VN) signals. The difference between these two voltages is defined as the hysteresis voltage (VH), which supports clean and stable output transitions even with slow or noisy input signals. The device operates without any external components, simplifying circuit design and reducing component count.

Key Features

• Schmitt-trigger action with no external components
• Hysteresis voltage of 3.5 V at VDD = 15 V
• Noise immunity greater than 50%
• No limit on input rise and fall times
• Standardised, symmetrical output characteristics
• 100% tested for quiescent current at 20 V
• Low VDD to VSS current during slow input ramps
• 5 V, 10 V and 15 V parametric ratings
• Meets all requirements of JEDEC tentative standard No. 13B

Applications and Performance

With noise immunity greater than 50%, this device is suited to industrial environments where signal integrity is critical. Its standardised output characteristics support predictable performance across the 3 V to 18 V supply range, and it is designed to handle slow or noisy input signals without external components. The IC is free from antimony (Sb) and bromine (Br). Its SOIC package with 14 pins suits space-constrained PCB designs, and the specified operating temperature range is -55 °C to 125 °C.

The IC is fully compliant with JEDEC tentative standard No. 13B and is available in a compact 14-pin SOIC package for efficient board layouts.
