| General Description

The ZJG4428 and ZJG4429 are analog multiplexers, with the ZJG4428 comprising eight single channels and the ZJG4429 comprising four differential channels. The ZJG4428 switches one of eight inputs to a common output as determined by the 3-bit binary address lines, A0, A1, and A2. The ZJG4429 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 each device is used to enable or disable the device. When disabled, all channels are switched off. They support bidirectional analog and digital signals on the source (Sx) and drain(D) pins.

The ZJG4428 and ZJG4429 provide latch-up immunity, preventing undesirable high current events between parasitic structures within the device typically caused by overvoltage events. A latch-up condition typically continues until the power supply rails are turned off and can lead to device failure. The latch-up immunity feature allows the ZJG4428 and ZJG4429 to be used in harsh environments.

The ZJG4428 and ZJG4429 are available in SOIC-16 and TSSOP-16 packages and are pin compatible with industry standards.
