Hex Schmitt Trigger Inverter in bare die form

Description
The CD40106B Hex Schmitt Trigger is a monolithic
complementary MOS (CMOS) integrated circuit constructed
with N-channel and P-channel enhancement transistors.
The positive and negative going threshold voltages, VT+ and
VT- , show low variation with respect to temperature (typ.
0.0005V/°C at VCC = 10V), and hysteresis, VT+ - VT- ≥ 0.2
VDD is guaranteed. All inputs are protected from damage
due to static discharge by diode clamps to VCC and GND.

Features:
 Wide supply voltage range: 3V to 15V
 High noise immunity: 0.70 VDD (typ.)
 Low power TTL compatibility:
o Fan out of 2 driving 74L or 1 driving 74LS
 Hysteresis:
o 0.40 VDD (typ.)
o 0.20 VDD (guaranteed).
