The CLOCK input is active on the rising edge. Both LOAD and CLEAR inputs are active LOW. Presetting is synchronous on the rising edge of the clock, the function is synchronous to the DIP SOP TSSOP ORDER CODES PACKAGE TUBE DIP SOP TSSOP M74HC163B1R M74HC163M1R T&R M74HC163RM13TR M74HC163TTR CLOCK. Two enable inputs (TE and PE) and CARRY output are provided to enable easy cascading of counters, which facilities easy implementation of N-bit counters without using external gates. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
