CD4029BC Presettable Binary/Decade Up/Down Counter October 1987 Revised January 2004 CD4029BC Presettable Binary/Decade Up/Down Counter General Description Features The CD4029BC is a presettable up/down counter whichWide supply voltage range: 3V to 15V counts in either binary or decade mode depending on theHigh noise immunity: 0.45 V (typ.) DD voltage level applied at binary/decade input. When binary/ Low power TTL compatibility: fan out of 2 driving 74L decade is at logical “1”, the counter counts in binary, other- or 1 driving 74LS wise it counts in decade. Similarly, the counter counts up Parallel jam inputs when the up/down input is at logical “1” and vice versa. Binary or BCD decade up/down counting A logical “1” preset enable signal allows information at the “jam” inputs to preset the counter to any state asynchro- nously with the clock. The counter is advanced one count at the positive-going edge of the clock if the carry in and preset enable inputs are at logical “0”. Advancement is inhibited when either or both of these two inputs is at logi- cal “1”. The carry out signal is normally at logical “1” state and goes to logical “0” state when the counter reaches its maximum count in the “up” mode or the minimum count in the “down” mode provided the carry input is at logical “0” state. All inputs are protected against static discharge by diode clamps to both V and V .
