description
The TL393 is a dual differential comparator built using a new Texas Instruments-developed bipolar process. The
TL393 is intended as an enhanced alternative to the industry-standard LM393 in circuits with supply-voltage
limits of 7 V.
The new bipolar process allows the TL393 to perform with lower supply-current requirements than the LM393
(0.7 mA typical) while still providing a faster response time than the older device.
Package availability for this device includes the TSSOP (thin-shrink small-outline package). With a maximum
thickness of 1.1 mm and a package area that is 25% smaller than the standard surface-mount package, the
TSSOP is ideal for high-density circuits, particularly in hand-held and portable equipment.

TL393Y chip information
This chip, when properly assembled, displays characteristics similar to the TL393. Thermal compression or
ultrasonic bonding may be used on the doped-aluminum bonding pads. Chips may be mounted with conductive
epoxy or a gold-silicon preform.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltage values, except differential voltages, are with respect to network GND.
2. Differential voltages are at IN+ with respect to IN .
3. Short circuits from the outputs to VCC can cause excessive heating and eventual destruction of the chip.
