TPT487

3.0V to 5.5V RS-485 Transceivers

Description

Features

The TPT487 are IEC61000 ESD protected, 3.0V to 5.5V

powered transceivers that meet the RS-485 and RS-422

standards for balanced communication.

⚫

Exceeds Requirements of EIA-485 Standard

Hot Plug Circuitry - Tx and Rx Outputs Remain Three-

State During Power-up/Power-down

Transmitters in this family deliver exceptional differential output

voltages into the RS-485 required 54Ω load. These 500kbps

devices have very low bus currents so they present a true “1/8

unit load” to the RS-485 bus. This allows up to 256 transceivers

on the network without using repeaters. Receiver (Rx) inputs

feature a “Full Fail-Safe” design, which ensures a logic high Rx

output if Rx inputs are floating, shorted, or on a terminated but

undriven bus.

⚫

Data Rate: 500 Kbps

Up to 256 Nodes on a Bus (1/8 unit load) at 500kbps

Full Fail-safe Receiver (Open, Short, Terminated)

Wide Supply Voltage 3V to 5.5V

Bus-Pin Protection:

±18 kV HBM ESD

±15 kV IEC61000-4-2 Contact Discharge

±18 kV IEC61000-4-2 Air Discharge

–40°C to 125°C Operation Temperature Range

TPT487 is designed for half-duplex RS485, and support SOP8，

MSOP8 and DFN3X3-8L package, which is characterized from

–40°C to 125°C.
