Add to Cart:

CD4026 or HCF4026 consists  of  a  5-stages  Johnson decade  counter  and  an  output  decoder  which converts   the   Johnson   code   to   a   7   segment decoded   output   for   driving   one   stage   in   a numerical   display.   This   device   is   particularly advantageous  in  display  applications  where  low power dissipation and/or  low package count are important.   This   device   has   CLOCK,   RESET, CLOCK  INHIBIT,  DISPLAY  ENABLE  input  and CARRY OUT, DISPLAY ENABLE, UNGATED "C" SEGMENT and 7 DECODED outputs (a to g). A high RESET signal clears the decade counter to its zero count. The counter is advanced one count at the positive clock signal transition if the CLOCK INHIBIT  signal  is  low.  Counter  advancement  via the   clock   line   is   inhibited   when   the   CLOCK INHIBIT signal is high. Antilock gating is provided on  the  JOHNSON  counter,  thus  assuring  proper counting   sequence.   The  CARRY-OUT   (COUT) signal  completes  one  cycle  every  ten  CLOCK INPUT cycles and is used to clock the succeeding decade directly in a multi-decade counting chain.
