The VHC4040 is a high-performance CMOS device with high input noise rejection, output high anti-interference ability and low power dissipation. It can be widely used in digital circuits.
The document describes the 74VHC4040, an advanced high-speed CMOS device fabricated with silicon gate technology. It functions as a 12-stage counter that increments on the negative edge of the clock input and features built-in input protection allowing operation from 5V to 3V systems.
The datasheet provides detailed electrical characteristics including DC and AC parameters for various supply voltages (3.0V to 5.5V), absolute maximum ratings, timing diagrams, logic symbols, and physical dimensions for three available package types: SOIC, TSSOP, and PDIP.
