Search the history of over billion web pages on the Internet. Full text of ” IC Datasheet: Synchronous operation Is provided by having all flip-flops clocked simultaneously so that the outputs change coincidently with each other when so instructed by the steering logic.

This mode of operation eliminates the output counting spikes which are normally associated with asynchronous ripple- clock counters. The outputs of the four master-slave flip-flops are trig- gered by a low-to-high-level transition of either count clock input. The direction of counting is determined by which count input Is pulsed while the other count input is high. The output will change to agree with the data In- puts independently of the count pulses.

This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs. A clear Input has been provided which forces all outputs to the low level when a high level is applied. The clear function is independent of the count and load Inputs.

The clear, count, and load inputs are buffered to lower the drive requirements. This reduces the number of clock drivers, etc.

These counters were designed to be cascaded without the need for external circuitry.

Both borrow and carry outputs are available to cascade both dataeheet up- and down-counting functions. The borrow output produces a pulse equal in width to the count-down input when the counter underflows, Similarly, the carry output produces a pulse equal in width to the count-up Input when an overflow condition exists. The counters can then be easily cascaded by feeding the borrow and carry outputs to the count-down and count-up inputs respectively of the succeeding counter. Voltage values are with respect to network ground terminal.

Production processing does not necessarily include vl’V testing of all parameters. Clear outputs to zero. Load preset to BCD seven. Count up to eight, nine, carry, datasneet, one, and two. Count down to one, zero, borrow, nine, eight, and seven. Clear overrides load, data, and count inputs. When counting up, count-down Input must be high; when counting down, count-up input must be high.

Load preset to binary thirteen. Count up to fourteen, fifteen, carry, zero, one, and two. Count down to one, zero, borrow, fifteen, fourteen, and thirteen. When counting up, count-down input must be high; when counting down, datxsheet input must be high.
