DM74AS169A Dettagli del prodotto

General Description
These synchronous presettable counters feature an internal carry look ahead for cascading in high speed counting applications. The DM74AS169 is a 4-bit binary up/down counter. The carry output is decoded to prevent spikes during normal mode of counting operation. Synchronous operation is provided so that outputs change coincident with each other when so instructed by count enable inputs and internal gating. This mode of operation eliminates the output counting spikes which are normally associated with asynchronous (ripple clock) counters. A buffered clock input triggers the four flip-flops on the rising (positive going) edge of clock input waveform.
These counters are fully programmable; that is, the outputs may each be preset either HIGH or LOW. The load input circuitry allows loading with carry-enable output of cascaded counters. As loading is synchronous, setting up a LOW level at the load input disables the counter and causes the outputs to agree with the data inputs after the next clock pulse.

Features

   and low power Schottky TTL counterpart
■ Improved AC performance over Schottky and low power
   Schottky counterparts
■ Synchronously programmable
■ Internal look ahead for fast counting
■ Carry output for n-bit cascading
■ Synchronous counting
■ Load control line
■ ESD inputs

A proposito di Fairchild Semiconductor


Fairchild Semiconductor era una società di semiconduttori pionieristici che fu fondata alla fine degli anni '50.
La società era nota per la sua innovazione nello sviluppo del primo transistor commerciale e per i suoi contributi al progresso della tecnologia del circuito integrato.
Fairchild è diventato un fornitore leader di semiconduttori di potenza, circuiti integrati analogici e di segnale misto e altri prodotti a semiconduttore.
La società è stata acquisita da Semiconductor nel 2016 e i suoi prodotti e tecnologie continuano a essere sviluppati e venduti con il marchio su semiconduttore.
