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.
