DESCRIPTION
HCF40103B is a monolithic integrated circuitfabricated in Metal Oxide Semiconductortechnology available in DIP and SOP packages. HCF40103B consists of an 8-stage synchronousdown counter with a single output that is activewhen the internal count is zero. This devicecontains a single 8-bit binary counter. It hascontrol inputs for enabling or disabling the clock,for clearing the counter to its maximum count, andfor presetting the counter either synchronously orasynchronously. All control inputs and theCARRY-OUT/ZERO DETECT output areactive-low logics. In normal operation, the counteris decremented by one count on each positivetransition of the CLOCK. Counting is inhibitedwhen the CARRY-IN/COUNTER ENABLE (CI/PIN CONNECTIONCE) input is high. The CARRY-OUT/ZERODETECT (CO/ZD) output goes low when thecount reaches zero if the CI/CE input is low, andremains low for one full clock period. When theSYNCHRONOUS PRESET ENABLE (SPE) inputis low, data at the JAM input is clocked into thecounter on the next positive clock transitionregardless of the state of the CI/CE input. Whenthe ASYNCHRONOUS PRESET ENABLE (APE)input is low, data at the JAM inputs isasynchronously forced into the counter regardlessof the state of the SPE, CI/CE, or CLOCK inputs.JAM inputs J0-J7 represent a single 8 bit binaryword. When the CLEAR (CLR) input is low, thecounter is asynchronously cleared to its maximumcount (25510) regardless of the state of any otherinput. The precedent relationship between controlinput is indicated in the truth table. If all control

inputs are high at the time of zero count, thecounters will jump to the maximum count, giving acounting sequence of 256 clock pulses long.IINPUT EQUIVALENT CIRCUIT
HCF40103B may be cascaded using the CI/CEinput and the CO/ZD output, in either asynchronous or ripple mode.PIN DESCRIPTION

* An Output spike (160ns at VDD = 5V) occurs whenever two or more devices are cascaded in the parallel clocked mode because the clock-to-carry out delay is greater than the carry-in-to-carry-out delay. This spike is eliminated by gating the output of the last device with the clock as shown.
