Technical content

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 12 0µA and 500µA 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 0.1µA. 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-impe 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 t he HWD481, HWD483, HWD485, HWD487, and HWD1487 are designed for half-duplex applications.

NOTES FOR ELECTRICAL/SWITCHING CHARACTERISTICS Note 1: All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise specified. Note 2: All typical specifications are given for VCC = 5V and TA = +25°C. Note 3: Supply current specification is valid for loaded transmitters when DE = 0V. Note 4: Applies to peak current. See Typical Operating Characteristics. Note 5: The HWD481/HWD483/HWD487 are put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 50ns, the parts are guaranteed not to enter shutdown. If the inputs are in this state for at least 600ns, the parts are guaranteed to have entered shutdown. See Low-Power Shutdown Mode section.
