Pin 7 — SCTEN — Enables SCT receiver;
active high; TTL input.
Pin 8 — LATCH — Latch control for decoder
bits (pins 9-12), active low. Logic high input
will make decoder transparent.
Pins 12–9 — DEC
– DEC
— Transmitter and
receiver decode register; configures transmitter
and receiver modes; TTL inputs.
Pin 18 — RLEN — Enables RL driver; active
low; TTL input.
Pin 23 — STEN — Enables ST driver; active
low; TTL input.
