SL4029B, Presettable Up/Down Counter

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 of a single CLOCK, CARRY IN,(CLOCK ENABLE), BINARY/DECADE, UP/DOWN, PRESET ENABLE, and four individual JAM signals.

Q1, Q2, Q3, Q4 and a CARRY OUT signal are provided as outputs.

A high PRESET ENABLE signal allows information on the JAM INPUTS to preset the counter to any stat
