TL7726 HEX CLAMPING CIRCUITS SLAS078C – SEPTEMBER 1993 – REVISED JULY 1999 (cid:0) Protects Against Latch-Up D OR P PACKAGE (cid:0) (TOP VIEW) 25-mA Current Sink in Active State (cid:0) Less Than 1-mW Dissipation in Standby GND 1 8 REF Condition CLAMP 2 7 CLAMP (cid:0) Ideal for Applications in Environments CLAMP 3 6 CLAMP Where Large Transient Spikes Occur CLAMP 4 5 CLAMP (cid:0) Stable Operation for All Values of Capacitive Load (cid:0) No Output Overshoot 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 m A. 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.
