The TL7726 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 < REF, the clamping circuits present a very high impedance to ground, drawing current of less than 10 uA. The clamping circuits are active for VI < GND or VI > REF when they have a very low impedance and can sink up to 25 mA.
These characteristics make the TL7726 ideal as protection devices for CMOS semiconductor devices in environments where there are large positive or negative transients to protect analog-to-digital converters in automotive or industrial systems. The use of clamping circuits provides a safeguard against potential latch-up.
The TL7726C is characterized for operation over the temperature range of 0°C to 70°C. The TL7726I is characterized for operation over the temperature range of -40°C to 85°C. The TL7726Q is characterized for operation over the temperature range of -40°C to 125°C.
