RESET
RESET
Output.
RESET
remains low while V
CC
is below the reset threshold, and for 280ms (max)
after V
CC
rises above the reset threshold.
9
INVALID
Output of the Valid Signal Detector. Asserts when no valid RS-232 levels are present on any of
the receiver inputs for 90μs.
7, 8
R_OUT
TTL/CMOS Receiver Outputs (R1OUT and R2OUT)

T_IN
TTL/CMOS Transmitter Inputs (T1IN and T2IN)

13, 14
R_IN
RS-232 Receiver Inputs (R2IN and R1IN)
12
FORCEON
Force-On Input. Drive FORCEON high to override AutoShutdown Plus, keeping transmitters on
(
FORCEOFF
must be high) (Table 1).
11
FORCEOFF
Force-Off Input. Drive
FORCEOFF
low to shut down transmitters and on-board power supply.
This overrides AutoShutdown Plus and FORCEON (Table 1).
