DESCRIPTION

The TSM931–TSM934 family of single/dual/quad,

low-voltage, micropower analog comparators is

electrically and form-factor identical to the MAX931-

MAX934 family of analog comparators. Ideal for 3V or

5V single-supply applications, the TSM931–TSM934

family can operate from single +2.5V to +11V

supplies or from ±1.25V to ±5.5V dual supplies. The

single TSM931 draws less than 4μA (max) supply

current over temperature. The dual TSM932/933 and

the quad TSM934 each draw less than 3μA per

comparator over temperature.

All comparators in this family exhibit an input voltage

range from the negative supply rail to within 1.3V of

the positive supply. In addition, the comparators’

push-pull output stages are TTL/CMOS compatible

and capable of sinking and sourcing current. The

TSM931/TSM932/TSM933 each incorporates an

internal 1.182V ±2% voltage reference. Without

complicated feedback configurations and only

requiring two additional resistors, adding external

hysteresis via a separate pin is available on the

TSM931, the TSM932, and the TSM933.

Electrical and thermal 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 condition beyond those indicated in the operational sections

of the specifications is not implied. Exposure to any absolute maximum rating conditions for extended periods may affect device reliability and

lifetime.
