LOW-POWER
RS-485 TRANSCEIVER
The
HVD3082E is a new low-power RS-485 transceiver that
cuts power consumption to less than 0.3 mA in Active mode.
The new transceiver features true fail-safe receiver inputs
and ESD protection; it is ideal for demanding applications
in noisy environments such as energy meter networks, industrial
automation, and telecom racks.
The
half-duplex transceiver is designed for RS-485 data bus
networks. Powered by a 5-V supply, it is fully compliant
with the TIA/EIA-485A standard. With controlled output transition
times, the device is suitable for signaling rates up to
200 kbps over long twisted-pair cables, and it features
a true fail-safe receiver design that detects and corrects
bus open, idle, and short conditions.
When
in the Inactive Shutdown mode, the supply current drops
to a 1-nA typical, making these devices ideal for power-sensitive
applications. In Active mode, the supply current is less
than 0.3 mA. The device also features ESD protection that
exceeds 16 kV. The SN75HVD3082E (0 to 70°C) and SN65HVD3082E
(–40° to 85°C) are available in an eight-pin SOIC package
and cost $0.51 and $0.56 in 1000-piece quantities,
respectively.
