FEATURES

DESCRIPTION

The LTC^®2856-1, LTC2856-2, LTC2857-1, LTC2857-2,

20Mbps or Low EMI 250kbps Maximum Data Rate

No Damage or Latchup to ESD: ±±5kꢀ ꢁHM

ꢁigh Input Impedance Supports 256 Nodes

(C, I-Grade)

LTC2858-1 and LTC2858-2 are low power, RS485/RS422

transceivers operating on 5V supplies at maximum data

rates of 20Mbps or 250kbps for low EMI. The receiver has

a one-eighth unit load, supporting up to 256 nodes per bus

(C, I-Grade), and a failsafe feature that guarantees a high

output state under conditions of floating or shorted inputs.

Operation Up to ±25°C (ꢁ-Grade)

Guaranteed Failsafe Receiver Operation Over the

Entire Common Mode Range

Current Limited Drivers and Thermal Shutdown

Delayed Micropower Shutdown: 5µA Maximum

(C, I-Grade)

Power Up/Down Glitch-Free Driver Outputs

Low Operating Current: 900µA Maximum in Receive

Mode

The driver maintains a high output impedance over the

entire common mode range when disabled or when the

supply is removed. Excessive power dissipation caused

by bus contention or a fault is prevented by current limit-

ing all outputs and by thermal shutdown.

Enhanced ESD protection allows these parts to withstand

15kV (human body model) on the transceiver interface

pins without latchup or damage.

Compatible with TIA/EIA-485-A Specifications

Available in 8-Lead and 10-Lead 3mm × 3mm DFN

and 8-Lead and 10-Lead MSOP Packages
