SC88E43
EXTENDED VOLTAGE CALLING
NUMBER IDENTIFICATION CIRCUIT 2
DESCRIPTION
The SC88E43 Calling Number Identification Circuit 2(ECNIC2) is
a low power CMOS integrated circuit intended for receiving physical
layer signals transmitted according to BT (British Telecom) SIN227
& SIN242, the U.K.’s CCA (Cable Communications Association)
TW/P&E/312 and Bellcore GR-30-CORE & SR-TSV-002476
specifications. The SC88E43 is suitable for applications using a
fixed voltage power source between 3 and 5V ±10%.
DIP-24
FEATURES
