HCF40161B is a 4-bit synchronous programmable counter. The CLEAR function is asynchronous. A low level at the CLEAR input sets all four outputs low regardless of the state of the CLOCK, LOAD and ENABLE inputs. A low level at the LOAD inputs disables the counter and causes the output to agree with the set-up data after the following CLOCK pulse regardless of the conditions of the DIP SOP ORDER CODES PACKAGE TUBE T&R DIP SOP HCF40161BEY HCF40161BM1 HCF40161M013TR ENABLE inputs. The carry look-ahead circuitry provides for cascading counter for n-bit synchronous application without additional gating. Counting is enabled when both the PE and TE inputs are high. The TE input is fed forward to enable COUT. This enable output produces a positive output pulse with a duration approximately equal to the positive portion of the Q1 output. This positive overflow carry pulse can be used to enable successive cascaded stages. Logic transitions at the PE and TE inputs may occur when the clock is either high or low.
