Description



Features:

Meets EIA standard RS485 for multipoint bus transmission and is compatible with RS-422
15 ns driver propagation delays with 2 ns skew (typical)
Single +5V supply
-7V to +12V bus common mode range permits ±7V ground difference between devices on the bus
Thermal shutdown protection
High impedance to bus with driver in TRI-STATE or with power off, over the entire common mode range allows the unused devices on the bus to be powered down
Combined impedance of a driver output and receiver input is less than one RS485 unit load, allowing up to 32 transceivers on the bus
70 mV typical receiver hysteresis

Description

The DS3695, DS3696, and DS3697 are high speed differen-tial TRI-STATE bus/line transceivers/repeaters designed to meet the requirements of EIAstandard RS485 with extended common mode range (+12V to -7V), for multipoint data transmission.

The DS3695, DS3696, and DS3697 driver and receiver outputs feature TRI-STATE capabil-ity. The driver outputs remain in TRI-STATE over the entire common mode range of +12V to -7V. Bus faults that cause excessive power dissipation within the device trigger a ther-mal shutdown circuit, which forces the driver outputs into the high impedance state. The DS3696 provides an output pin TS (thermal shutdown) which reports the occurrence of the thermal shutdown of the device. This is an "open collector"pinwithaninternal10k?pull-upresistor.Thisallowstheline fault outputs of several devices to be wire OR-ed.

BothAC and DC specifications of DS3695, DS3696, and DS3697 are guaranteed over the 0 to 70 temperature and 4.75V to 5.25V supply voltage range.
