Overview
The AD7501JN, produced by Analog Devices Inc., is a monolithic CMOS, 8-channel analog multiplexer. This device is designed to switch one of eight inputs to a common output based on the state of three binary address lines and an 'enable' input. The AD7501JN is part of the AD7501 and AD7503 series, with the AD7503 being identical to the AD7501 except for the inverted 'enable' logic. This component is highly versatile and compatible with TTL/DTL and CMOS logic, making it suitable for a variety of analog switching applications.
