It includes a input inverter utilizing a charge-pump technique, therefore it can provide both a just inverted output (-Vo) and a twice inverted output (-2Vo) by connecting an external capacitor. It can also switch over between a stand-by mode (a halt function with low power dissipation) and a double clocking mode for reducing output ripples. PIN CONFIGURATION(TOP VIEW) FEATURE • Availability of two outputs ; just inverted and twice inverted output • Capability of output current ------- 30mA (min) • Low voltage operation ------- Vin = 3V (typ) • Low stand-by current (standby mode) • Low out ripple (double clocking mode) • Small 10-pin package COSC 1 VCC 2 9 CP1 3 8 -VO GND 4 7 -2VO CP2 5 6 10 STB DCLK CP3 OUTLINE 10P2N APPLICATION • MMICs for a handy telephone and a PHS BLOCK DIAGRAM VCC=3V(typ) CP2 CP1 VCC 2 3 5 CP3 6 COSC 1 Oscillator 10 9 STB DCLK Timing adjustment Double clock generator Double clock selector -2VO CHARGE SW. 7 -VO CHARGE SW. 4 8 GND MITSUBISHI (1 / 3) L Yificatioon.change.
