TD6347F

TD6347S/F TOSHIBA BIPOLAR DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC TD6347S,TD6347F CONVENTIONAL TIMER The TD6347S、TD6347F is an automotive I2L monolithic timer. It is a long-term timer superior in voltage and temperature characteristics. It produces an NPN transistor open-collector output. The IC has three inputs : start / reset and two modes, so that it can be used in a variety of application fields. FEATURES l Small standby current : 1mA l 3 inputs : start / reset and two modes l Power-on reset function incorporated l Good voltage characteristics : ± 0.05% / V l Good temperature characteristics : ± 0.02% / °C l Output current / output withstand voltage : 250mA / 30V l SIP9-PIN (TD6347S) l SSOP10-PIN (TD6347F) TD6347S TD6347F Wegiht SIP9-P-2.54A : 0.92 g (Typ.) SSOP10-P-225-1.00 : 0.10 g (Typ.) 1 2002-02-27 BLOCK DIAGRAM AND PIN LAYOUT TD6347S/F Note: TD6347S and TD6347F are the same chip; only the packages are different. 2 2002-02-27 PIN DESCRIPTION PIN No. TD6347S TD6347F 12 SYMBOL DI1 DESCRIPTION Connected to the input switch. When this pin is grounded, the IC accepts the input, and the output is reversed. The input circuit is shown at right. TD6347S/F 23 34 DI2 When this pin is grounded, the IC is reset. The input circuit construction is the same as that of DI1 . When the input switch is connected and this pin is grounded, the output turns off. When this pin is connected to VCC, the output turns on. The input circuit is shown at right....
