General Description
The HWD481, HWD483, HWD485, HWD487–HWD491, and
HWD1487 are low-power transceivers for RS-485 and RS-
422 communication. Each part contains one driver and one
receiver. The HWD483, HWD487, HWD488, and HWD489
feature reduced slew-rate drivers that minimize EMI and
reduce reflections caused by improperly terminated cables,
thus allowing error-free data transmission up to 250kbps.
The driver slew rates of the HWD481, HWD485, HWD490,
HWD491, and HWD1487 are not limited, allowing them to
transmit up to 2.5Mbps.
These transceivers draw between 120A and 500A of
supply current when unloaded or fully loaded with disabled
drivers. Additionally, the HWD481, HWD483, and HWD487
have a low-current shutdown mode in which they consume
only 0.1A. All parts operate from a single 5V supply.
Drivers are short-circuit current limited and are protected
against excessive power dissipation by thermal shutdown
circuitry that places the driver outputs into a high-imped-
ance state. The receiver input has a fail-safe feature that
guarantees a logic-high output if the input is open circuit.
The HWD487 and HWD1487 feature quarter-unit-load
receiver input impedance, allowing up to 128 HWD487/
HWD1487 transceivers on the bus. Full-duplex communi-
cations are obtained using the HWD488–HWD491, while
the HWD481, HWD483, HWD485, HWD487, and HWD1487
are designed for half-duplex applications.
