TTL/CMOS level receiver outputs.
Active low output that indicates if no valid RS-232 levels are present on any receiver input.
Active high input to override automatic powerdown circuitry thereby keeping transmitters active. (FORCEOFF must be high).
Active low receiver enable control.

Ordering Information
NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J Std-020B.
