TL7726CPG4

TEXAS INSTRUMENTS  TL7726CPG4  六角钳位电路, 4.5V-5.5V输入, DIP-8

The is a Hex Clamping Circuit that monitors 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 10µA. The clamping circuits are active for VIREF when they have a very low impedance and can sink up to 25mA. 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 analogue-to-digital converters. The use of clamping circuits provides a safeguard against potential latch-up. It is ideal for applications in environments where large transient spikes occur.
