GENERAL DESCRIPTION
The ADG428 and ADG429 are monolithic CMOS analog multiplexers comprising eight single channels and four differential channels respectively. On-chip address and control latches facilitate microprocessor interfacing. The ADG428 switches one of eight inputs to a common output as determined by the 3-bit binary address lines A0, A1 and A2. The ADG429 switches one of four differential inputs to a common differential output as determined by the 2-bit binary address lines A0 and A1. An EN input on both devices is used to enable or disable the device.
