description
The TL7726 consists of six identical clamping circuits that monitor an input voltage with respect to a reference
value, REF. For an input voltage (V ) in the range of GND to < REF, the clamping circuits present a very high
I
impedance to ground, drawing current of less than 10 µA. The clamping circuits are active for V < GND or
I
V > REF when they have a very low impedance and can sink up to 25 mA.
I
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.
