CMOS DIGITAL INTEGRATED CIRCUIT T0502 7BP = SILICON MONOLITHIC — SILICON MONOLTTHIC eNe TC5027BP BINARY COUNTER TC5027BP is four bit binary up counter with the reset function and since the clock for the first stage is independent from the clock for the second through the fourth stages, this can be used as binary, octal or hexadecimal counter/divider. i When two inputs of RESET(0) are set to "H", the “ content of counter is reset to 0 regardless of the 2 clock. The outputs change their states at the SIP 14 (8D14a-P) falling edge of count inputs (INA, INB).
