Hex clamping circuit, TL7726CP, Texas Instruments

The TL7726CP consists of six identical clamping circuits that monitor an input voltage with respect to a reference value, REF. For an input voltage (VI) in the range of GND to less than REF, the clamping circuit presents a very high impedance to ground, drawing a current of less than 10 µA. The clamping circuit becomes active when VI is less than GND or greater than REF, exhibiting very low impedance and capable of sinking up to 25 mA.

These characteristics make the TL7726CP ideal as a protection device for CMOS semiconductor devices in environments with large positive or negative transients, such as protecting analog-to-digital converters in automotive or industrial systems. The use of the clamping circuit provides a safeguard against potential latch-up.
