VIL = 0.8V (MAX) PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 163 DIP SOP TSSOP ORDER CODES PACKAGE DIP SOP TSSOP TUBE M74HCT163B1R M74HCT163M1R T&R M74HCT163RM13TR M74HCT163TTR DESCRIPTION The M74HCT163 is an high speed CMOS SYNCHRONOUS 4 BIT BINARY PRESETTABLE COUNTER fabricated with silicon gate C2MOS technology. 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 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.
