Low Cost 24V SLIC For PABX / Key

Systems

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.

NOTE: Intersil Pb-free products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin

plate termination finish, which is compatible with both SnPb and

Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed

the Pb-free requirements of IPC/JEDEC J Std-020B.
