... SL4029B Presettable Up/Down Counter High-Voltage Silicon-Gate CMOS The SL4029B consists of a four-stage binary or BCD-decade up/down counter with provisions for look-ahead carry in both counting modes. The inputs consists CARRY IN,(CLOCK ENABLE), PRESET ENABLE, and four individual JAM signals. Q1, Q2, Q3, Q4 and a CARRY OUT signal are provided as outputs. ...
