The M74HC163 is a high speed CMOS SYNCHRONOUS 4 BIT BINARY PRESETTABLE COUNTER fabricated with silicon gate C2MOS technology. It has a working frequency up to 62 MHz, low input current down to 4µA, wide static voltage range (2V to 6V), high noise immunity and symmetrical output impedance.
The M74HC163 is a high‑speed CMOS synchronous 4‑bit binary presettable counter with a wide operating voltage range (2 V to 6 V) and low power dissipation. It features active‑low CLEAR and LOAD inputs, active‑high CLOCK, and dual enable inputs (TE and PE) that simplify cascading multiple counters.
The document includes a detailed pin description, truth table, logic diagram, timing charts, absolute maximum ratings, recommended operating conditions, DC and AC electrical specifications, capacitive characteristics, and mechanical data for the TSSOP‑16 package.
