The ripple clock output produces a low-level output pulse equal datasheett width to the low- level portion of the clock input when an overflow or underflow condition exists.

up/down decade counter help | Electronics Forum (Circuits, Projects and Microcontrollers)

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 data at the data inputs. A short-lived 64 prefix on Texas Instruments parts indicated an industrial temperature range; this prefix had been dropped from the TI literature by A few alphabetic characters to designate a specific logic subfamily may immediately follow the 74 or 54 in the part number, e.

Synchronous operation is provided by having all flip- flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the steering logic. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed.

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.

Surface mount parts with a single gate often in a 5-pin or 6-pin package are prefixed with G instead of A high at the enable input inhibits counting.

For more details, refer primarily to the Texas Instruments documentation mentioned in the References section. Data inputs B and C are held at the low logic level. Lqad preset to binary thirteen. To test Qq output of ‘ and ‘LS I think my wording is correct, it’s been awhile since my intro to digital design class. The output will change to agree with the data inputs independently of the level of the clock input. All data inputs are low.
