(1) The signaling rate of a line is the number of voltage
transitions that are made per second expressed in the units
bps (bits per second).
3 Description
The SN65HVD3x-EP devices are 3-state differential
line drivers and differential-input line receivers that
operate with 3-V power supply.
Each driver and receiver has separate input and
output pins for full-duplex bus communication
designs. They are designed for balanced
transmission lines and interoperation with ANSI
TIA/EIA-485A, TIA/EIA-422-B, ITU-T v.11, and ISO
8482:1993 standard-compliant devices.
The SN65HVD30, SN65HVD31, and SN65HVD32
are fully enabled with no external enabling pins.
The SN65HVD33, SN65HVD34, and SN65HVD35
have active-high driver enables and active-low
receiver enables. A low (less than 1 μA) standby
current can be achieved by disabling both the driver
and receiver.
All devices are characterized for operation from
–55°C to 125°C.
