Previous 1 2 State changes of the counters are synchronous with the. The input pulses are supplied by generators having the following characteristics: These counter change on the positive transition of the clock input. When low, the counter count up and when high, it counts down.

SN54′, SN74′ Circuits 5. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed. Conditions on other inputs are irrelevant. This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs.

Tl does not warrant or represent that any license, either express or implied, is granted under any Tl patent right, copyright, mask work right, or other Tl intellectual property right relating to any combination, machine, or process in which Tl products or services are used. Count down to one, zero minimumnine, eight, and seven. Minimum count enable time is the interval immediately preceeding the rising edge of the clock pulse during which interval the count enable input must be low to ensure counting.

These counters are fully programmable; that is, the outputs may be preset to either level by placing a low on the load input and entering the desired datashret at the data inputs. Count down to one, zero minimumfifteen, fourteen, and thirteen.

Count up to fourteen, fifteen maximumzero, one, and two. Voltage values are with respect to network ground terminal. Data inputs B and C are held at the low logic level.

In the counting modes, state changes are initiated by the rising edge of the. Count up to eight, nine maximumzero, one, and two. Pin numbers shown are for D, J, and N packages. To minimize the risks associated with customer products and applications, customers should datassheet adequate design and operating safeguards.

All data inputs are low. Tl assumes no liability for applications assistance or customer product design. Errors in Truth Table. A disadvantage ofdoesn’t apply, because the TC output of a given stage is not affected by its own CE.

Reproduction of this information with alteration is an unfair and deceptive business practice. Two outputs have been made available to perform the cascading function: To test Qq output of ‘ and ‘LS Delete arrow from 15 to 0.

I qq is measured with all inputs grounded and all outputs open. Wh en low, the counter counts up and when high, it counts down.

Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, Tl will not be responsible for any failure to meet such requirements.
