The MC14490DWG is an Arithmetic Logic Unit (ALU) LOG CMOS 3 to 18V HEX BOUNCE ELIMINATOR designed and manufactured by ON Semiconductor. This device is designed to provide logic operations, arithmetic functions, decoding and encoding, data buffering and arithmetic operations in digital systems. This device is made up of 8 logic gates interconnected in an array of logic functions. It features a small package size (making it ideal for applications with space constraints) and a wide operating voltage range (making it suitable for use in applications operating at different voltages). It also features hex bounce elimination, which prevents system malfunction caused by unwanted signals in the system. Furthermore, the device is protected against transient overvoltage by an internal ESD protection diode, making it suitable for use in harsh environments. With its high reliable performance and low power consumption, the MC14490DWG is an ideal choice for a wide range of applications.
