U-BUS Input/Output Transformer
TEW6018
TEW6018 is designed to inter-
face with the subscribers prem-
ises (NT) and the 2- wire line
side of the Central Office Equip-
ment (LT) in the ISDN Network.
TEW6018 meet the electrical re-
quirements for the
MOTOROLA MC145572 de-
vice.
TEW6018-S is the SMD version
Features:
• Low profile construction.
• Up to 50 mA line current.
• TEW6018 meets the
requirements of BS6301
for reinforced insulation,
clearance and creepage
distances between the line
and the device side.
