IW4029B
Presettable Up/Down Counter
High-Voltage Silicon-Gate CMOS
The IW4029B 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 state asynchronously with the clock. ORDERING INFORMATION A low on each JAM line, when the PRESET-ENABLE signal is high, IW4029BN Plastic resets the counter to its zero count.
