DI CMOS ANALOG SWITCHES WITH DATA LATCHES

GENERAL DESCRIPTION The AD7590DI, AD7591DI and AD7592DI are a family of protected (latch-proof) dielectrically isolated CMOS switches featuring overvoltage protection up to ±25V above the power supplies. Microprocessor interfacing is facilitated by the provision of on-chip data latches.

Subscriber Line Interface Circuit Protector

Description The L7591 Subscriber Line Interface Circuit (SLIC) Protector is designed to protect line-feed circuitry from fault-induced lightning and power-cross surge pulses. If a fault current forces TIP and/or RING to a more negative voltage than VS, current is conducted through the trip circui
