5-volt low level serial transceiver

摘要

A transceiver has a transmitter portion using active comparators coupled to a single low level positive bias source to enable low powered drain transmit and receive conversion of TTL input signals to LLS (low level serial) data output signals for a coaxial data transmission cable. The transceiver also provides a constant impedance for a coaxial or triaxial transmission cable during active transmission periods, standby periods and power-off periods to provide a cost effective method to transmit and receive data.
