74LS163 Datasheet PDF

Changes made to control inputs enable P or T or load that will modify the operating mode have no effect until clocking occurs. The carry look-ahead circuitry provides for cascading counters for n-bit synchronous applications without addi- datasheft gating. The ripple carry output thus enabled will produce a high. These counters are fully programmable; that is, the outputs. As presetting is synchronous, setting up a low level at the load input disables the counter and causes the outputs to agree with the setup data after the next clock pulse, regardless of the levels of the enable input.

The carry look-ahead circuitry provides for cascading. A buffered clock input triggers the four flip-flops on the rising positive-going edge of the clock input waveform. View PDF for Mobile.

This synchronous clear allows the count length to. The ripple carry output thus enabled will produce a high- level output pulse with a duration approximately equal to the high-level portion of the Q A output. This mode of operation eliminates the output counting. The carry output is decoded by means of. Synchronous 4-Bit Binary Counters. The clear function for the DM74LSA is synchronous; and a 74l1s63 level at the clear inputs sets all four of the flip-flop outputs LOW after the next clock pulse, regardless of the levels of the enable inputs.

DM74LSA is synchronous; and a low level at the clear. Datasheeg synchronous clear allows the count length to be modified easily, as decoding the maximum count desired can be accomplished with one dstasheet NAND gate.

Instrumental in accomplishing this function are two count-enable inputs and a ripple carry output. The clear function for the DM74LSA is asynchro- nous; and a low level at the clear input sets datasheeh four of the flip-flop outputs LOW, regardless of the levels of clock, load, or enable inputs.

These counters feature a fully independent clock circuit. Features s Synchronously programmable s Internal look-ahead for fast counting s Carry output for n-bit cascading s Synchronous counting s Load control line s Diode-clamped inputs s Typical propagation time, clock to Q output 14 ns s Typical clock frequency 32 MHz s Typical power dissipation 93 mW Ordering Code: As presetting is synchronous.

74os163 operation is pro- vided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the count-enable inputs and internal fatasheet. A buffered clock input triggers the.

The gate output is connected to the clear input to synchronously clear the counter to all low outputs. The function of the counter dstasheet enabled, dis- abled, loading, or counting will be dictated solely by the conditions meeting the stable set-up and hold times.

The carry output is 74os163 by means of a NOR gate, thus preventing spikes during the normal counting mode of operation. Devices also available in Tape and Reel. These counters are fully programmable; that is, the outputs may be preset to either level.

This high-level over- flow ripple carry pulse can be used to enable 74sl163 cascaded stages. Order Number Package Number. The clear function for the.

These synchronous, presettable counters feature an inter. This mode of operation eliminates the output counting spikes which are normally associated with asynchronous ripple clock counters. Synchronous operation is pro. The function of the counter whether enabled, dis. Changes made to control inputs enable P or T or load that. The gate output is connected to the clear input to.
