DESCRIPTION

The TLC393 consists of dual independent micropower voltage comparators designed to operate from a single

supply. It is functionally similar to the LM393 but uses one-twentieth the power for similar response times. The

open-drain MOS output stage interfaces to a variety of loads and supplies. For a similar device with a push-pull

output configuration see the TLC3702 data sheet.

Texas Instruments LinCMOS™ process offers superior analog performance to standard CMOS processes. Along

with the standard CMOS advantages of low power without sacrificing speed, high input impedance, and low bias

currents, the LinCMOS™ process offers extremely stable input offset voltages, even with differential input

stresses of several volts. This characteristic makes it possible to build reliable CMOS comparators.

The TLC393Q is characterized for operation over the full automotive temperature range of T

= −40°C to 125°C

TLC393-Q1 SGLS198B – SEPTEMBER 2004 – REVISED MAY 2013 www.ti.com PARAMETER MEASUREMENT INFORMATION The TLC393 contains a digital output stage which, if held in the linear region of the transfer curve, can cause damage to the device. Conventional operational amplifier/comparator testing incorporates the use of a servo loop that is designed to force the device output to a level within this linear region.

TLC393-Q1 SGLS198B – SEPTEMBER 2004 – REVISED MAY 2013 www.ti.com APPLICATION INFORMATION The input should always remain within the supply rails in order to avoid forward biasing the diodes in the electrostatic discharge (ESD) protection structure. If either input exceeds this range, the device will not be damaged as long as the input current is limited to less than 5 mA. To maintain the expected output state, the inputs must remain within the common-mode range.
