The M74HC298B1R from STMicroelectronics is a high-speed CMOS Quad 2 Channel Multiplexer/Register fabricated with silicon gate C2MOS technology. This device is controlled by WORD SELECT and CLOCK signals, allowing selection between two input words for each of the four multiplexer channels.
Key electrical characteristics include a high operating frequency of up to 79 MHz at 6V, low power dissipation with a typical quiescent current of 4μA at 25°C, and high noise immunity. The device supports a wide operating voltage range from 2V to 6V and offers symmetrical output impedance with a minimum current of 4mA.
Designed for through-hole mounting, the M74HC298B1R comes in a 16-DIP package. Its inputs are equipped with protection circuits against static discharge and transient excess voltage, making it suitable for various digital logic applications requiring multiplexing functionality.
