TA7522SG/FG
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TA7522SG,TA7522FG
Dual Voltage Comparator
The TA7522SG is an easy-to-use IC incorporating two voltage comparator circuits. Since one channel has an inverted-output buffer, a CR oscillator can be easily built up. The TA7522FG is in 8-pin dual inline package. The IC incorporating two-circuit package. It does not contain an inverted buffer output. In addition, the TA7522SG/FG have a wide operating temperature range that allows it to be used in a wide variety of applications.

Note 1: The absolute maximum ratings of a semiconductor device are a set of specified parameter values which must not be exceeded during operation, even for an instant. If any of these levels is exceeded during operation, the device's electrical characteristics may be irreparably altered and the reliability and lifetime of the device can no longer be guaranteed, possibly causing damage to any other equipment with which it is used. Applications using the device should be designed such that the absolute maximum ratings will never be exceeded in any operating conditions. Ensuring that the parameter values remain within these specified ranges during device operation will help to ensure that the integrity of the device is not compromised. Note 2: PD: TA7522SG/TA7522FG
