NLC322522T-180K-PF - Brand New TDK Corporation IC Chips
-
Description
The NLC322522T-180K-PF is a Dual ProSLIC® IC that combines the SLIC (Subscriber Line Interface Circuit) and CODEC (Coder-Decoder) functionality into a single low-voltage CMOS device. It is designed to provide a complete two-channel analog telephone interface according to LSSGR, ITU, and ETSI standards. With the inclusion of a linefeed IC (LFIC), it offers a comprehensive solution for telecom applications.
