receiver enables. A low, less than 1mA, standby

current can be achieved by disabling both the driver

• 5-V Devices available, SN65HVD50-55

and receiver.

(1)

Line Signaling Rate is the number of voltage transitions made

per second expressed in units of bps (bits per second).

All devices are characterized for ambient

temperatures from –40°C to 85°C. Low power

APPLICATIONS dissipation allows operation at temperatures up to

105°C or 125°C, depending on package option.

SN65HVD30 – SN65HVD35 www.ti.com SLLS665I – SEPTEMBER 2005 – REVISED APRIL 2010 DEVICE INFORMATION LOW-POWER STANDBY MODE When both the driver and receiver are disabled (DE low and RE high) the device is in standby mode. If the enable inputs are in this state for less than 60 ns, the device does not enter standby mode. This guards against inadvertently entering standby mode during driver/receiver enabling.
