HC5503 Functional Diagram
Description
Support is limited to customers who have already adopted these products.
The Intersil HC5503 low cost SLIC is optimized for use in small Analog or mixed Analog and Digital Key Telephone Systems (KTS) or PBX products. The low component count solution and surface mount package options, enable a small desktop Key System/PBX product to be achieved. The internal power dissipation of the end product is minimized by the low power consumption and minimal power supply voltage requirements of the HC5503. The HC5503 integrated solution provides higher quality, higher reliability and better performance solution than a transformer, thick film hybrid or discrete analog subscriber interface design. The HC5503 is designed in a Dielectrically isolated bipolar technology and is inherently latch proof and does not require hot plug or power supply sequencing precautions.
Applications
