Intersil has announced a new family of line card access switches (LCAS) featuring latch up immunity, low power consumption and higher density for telephone communications equipment. The ISL5571, ISL5572 and ISL5573 are multiple relay replacement ICs for a broad range of voice-band communication products, including digital loop carrier and pairgain remote terminals, digital subscriber line (DSL) cards and Central Office and PABX switches.
These ICs are much smaller than electromechanical relays, and require less than 10% of the operating power, shrinking the space and power consumption of telecommunications systems, says Intersil. They use less than 10 mW when switches are activated, compared with up to 150 mW for an electro- mechanical relay coil. The trenched Bonded Wafer technology also results in immunity to latch-up for increased reliability making the devices effectively immune to surge conditions or incorrect power supply on the subscriber line that can destroy conventional ICs.
Intersil's LCAS devices also include secondary protection circuitry to divert hazardous voltages to ground and, together with the SLIC, protect the other line circuit electronics. The three Intersil devices include the ISL5571, a ringing access switch; the ISL5572, which is a ringing access switch with one test access switch; and the ISL5573, a ringing access switch with two test access switches.
Bounce-free switching also results in low impulse noise for mixed voice and high-speed data lines, lower bit error rates on connections, and non-degrading switch contacts during inductive load switching

As soon as electronics and electrical systems started interfering with each other, the world had to come to some consensus. Considering physics is universal and does not care about what country electrical/electronic products are used in, it should be the same everywhere, right? It is nearly there, but not quite.
