SN65HVD3x-EP 3.3-V Full-Duplex RS-485 Drivers And Receivers
1 Features
3 Description
The SN65HVD3x-EP devices are 3-state differential

1/8 Unit-Load Option Available (up to 256 Nodes
line drivers and differential-input line receivers that
on the Bus)
operate with 3-V power supply.
Bus-Pin ESD Protection Exceeds 15 kV HBM
Each driver and receiver has separate input and
Optional Driver Output Transition Times for

Signaling Rates (1) of 1 Mbps, 5 Mbps, and
designs.
They
are
designed
for

transmission lines and interoperation with ANSI
Low-Current Standby Mode: <1
μA
TIA/EIA-485A, TIA/EIA-422-B, ITU-T v.11, and ISO
8482:1993 standard-compliant devices.
Glitch-Free Power-Up and Power-Down Protection
for Hot-Plugging Applications
The SN65HVD30, SN65HVD31, and SN65HVD32
are fully enabled with no external enabling pins.
5-V Tolerant Inputs
Bus Idle, Open, and Short-Circuit Fail Safe
The SN65HVD33, SN65HVD34, and SN65HVD35
have

active-low
Driver Current Limiting and Thermal Shutdown
receiver enables. A low (less than 1
μA) standby
Meet or Exceed the Requirements of ANSI
current can be achieved by disabling both the driver
TIA/EIA-485-A and RS-422 Compatible
and receiver.
All devices are characterized for operation from
