= 150V to 200V transient protector. PTC used as ring
generator ballast.
* Secondary protection diode bridge recommended is 3A, 200V
type.
**TF1, TF2 and RF1, RF2 are on PLCC only and should be con-
nected together as shown.
***Not Present on DIP or SOIC packages.
NOTES:
1. All grounds (AG, BG, & DG) must be applied before V
B
+ or V
B
-. Failure to do so may result in premature failure of the part. If a user wishes
to run separate grounds off a line card, the AG must be applied first.
2. Application shows Ring Injected Ringing, a Balanced or Tip injected configuration may be used.
