6 Detailed Description

6.1 Overview

The TLV703x and TLV704x are nano-power comparators with push-pull and open-drain outputs. Operating

from 1.6V to 6.5V and consuming only 315nA, the TLV703x and TLV704x are designed for portable and

industrial applications. The TLV703x and TLV704x are available in a variety of leadless and leaded packages to

offer significant board space saving in space-challenged designs. The TLV70x1S and TLV70x1L offer alternate

pinouts with an exteded 1.2V minimum supply.

6.3 Feature Description

The TLV703x and TLV704x devices are nanoPower comparators that are capable of operating at low voltages.

The TLV703x and TLV704x feature a rail-to-rail input stage capable of operating up to 100mV beyond the VCC

power supply rail. The TLV703x (push-pull) and TLV704x (open-drain) also feature internal hysteresis.

6.4 Device Functional Modes

The TLV703x and TLV704x have a power-on-reset (POR) circuit. While the power supply (VS) is less than the

minimum supply voltage, either upon ramp-up or ramp-down, the POR circuitry is activated.

For the TLV703x, the POR circuit holds the output low (at VEE) while activated.

For the TLV704x, the POR circuit keeps the output high impedance (logical high) while activated.

When the supply voltage is greater than, or equal to, the minimum supply voltage, the comparator output reflects

the state of the differential input (VID).
