Design Parameters: Ring Trip Threshold = 90mA
pedance = 210k /400 = 525 , with 39 protection resistors, impedance across Tip and Ring terminals = 603 . Where applicable, these compo-
nent values apply to the Basic Application Circuits for the HC55180, HC55181, HC55182, HC55183 and HC55184. Pins not shown in the Basic
Application Circuit are no connect (NC) pins.
