Revision A1
Line Driver Block 1488
This block contains six line drivers that are designed to serve as an interface between data terminal
equipment and data communications equipment in conformance with the specifications of EIA
standard RS-232C. The power requirements are +12V, 0V, and -12V.
Line Receiver Block 1489
This block contains ten line receivers that are designed to serve as an interface between data
terminal equipment and data communications equipment in conformance with the specifications of
EIA standard RS-232C. The power requirements are +12V, 0V, and -12V.
Power-Down Control Mode
When pin PDCIN is set active (active high or low determined by RVOP1 at power-on reset), the
W83768 enters power-down mode, and all output buffers (SD0, SD1, SD4, SD5,
RVOP1 10
DROP1

) will enter tri-state to reduce power consumption.
