In/Output Transformer
TEW4974
SCOPE
TEW4974 and TEW4974-1 are
designed to operate in the 64 kbit
mode of the CCITT
recommendation G703 for
Hierarchical Digital Interfaces.
Applications:
Codirectional Interface
Contradirectional Interface
Features:
• TEW4974 is specifically designed
to meet the stringent BS6301
requirements for reinforced barrier
insulation.
• TEW4974 is fully encapsulated in
epoxy to ensure 4000V dielectric
strength.
• TEW4974-1 has an electrostatic
shield for improved noise rejection.
