TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC The TA8029S is a small 9-pin SIP IC incorporating an accurate frequency /voltage converter and two voltage comparators. => It has a Schmitt input circuit and becomes active on the ————- positive edge of the input. Its F/V output is stable even —_— an when it is supplied with a high-frequency input. Since <p the Vcc pin connects to a shunt regulator, stable frequency detection is assured regardless of the battery i voltage. In addition, its wide operating temperature U . range allows it to be used for a wide variety of v applications. SIP9-P-2.540 Weight : 0.92g (Typ.)
