TA7522F

TA7522S/F TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA7522S,TA7522F Dual Voltage Comparator The TA7522S/TA7522F 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. In addition, the IC has a wide operating temperature range that allows it to be used in a wide variety of applications. TA7522S Features Two-circuit package High gain Single 3 V power supply for operation Inverted-output also available 0 V input causes action in the IC with a single power supply. Wide common-mode input range No latch-up Operating temperature range: −40 to 85°C Open-collector output SIP-9 pin (TA7522S) SOP-8 pin (TA7522F) Weight SIP9-P-2.54A : 0.92 g (typ.) SOP8-P-225-1.27 : 0.08 g (typ.) TA7522F 1 2005-03-29 TA7522S/F Block Diagram and Pin Layout TA7522S TA7522F Note 1: The TA7522S and TA7522F are the same chip housed in different packages.
