14 STAGE BINARY COUNTER/OSCILLATOR

Transcription

1 14 STAGE BINAY COUNTE/OSCILLATO The is an high speed CMOS 14-STAGE BINAY COUNTE/OSCILLATO fabricated with silicon gate C 2 MOS technology. The oscillator configuration allows design of either C or crystal oscillator circuits. A high level on the CLEA accomplishes the reset function, i.e. all counter outputs are made low and the oscillator is disabled. A negative traition on the clock input increments the counter. Ten kinds of divided output are provided; 4 to 10 and 12 to 14 stage inclusive. The maximum division available at 12 is 1/16384 f oscillator. The Clock Input ( I) and the CLEA input are equipped with protection circuits agait static discharge and traient excess voltage.. o LOW POWE ISSIPATION: I CC =4 μa(max.) at T A =25 C o SYMMETICAL OUTPUT IMPEANCE: I O = I OL = 4 ma (MIN) o BALANCE POPAGATION ELAYS: t PL = t PL o WIE OPEATING VOLTAGE ANGE: (OP) = 2 V to 6 V OEING INFOMATION N Plastic W SOIC T A = -55 to 125 C for all packages PIN ESCIPTION PIN No SYMBOL NAME AN FUNCTION 01, 02, to 14 Counter Outputs 07, 05, 04, 06, 14, 13, 15 4 to 10 Counter Outputs 09 O External Capacitor Connection 10 O External esistor Connection 11 I Clock Input / Oscillator 12 CLEA Master eset 08 GN Ground (0V) 16 Positive Supply PIN ASSIGNMENT CLEA I O O INPUT AN OUTPUT EUIVALENT CICUIT INPUT OUTPUT GN GN
