DS3695N

Overview

The DS3695N is a multipoint RS485/RS422 transceiver manufactured by Texas Instruments. It operates on a single +5V supply and supports data rates up to 10 Mb/s with typical driver propagation delays of 15 ns and skew of 2 ns. The device features TRI-STATE outputs, a common mode range of -7V to +12V, and thermal shutdown protection. It is housed in an 8-pin PDIP package and complies with EIA standard RS485.

Feature Summary

• Supports multipoint bus communication compliant with EIA standard RS485 and compatible with RS-422.
• Features TRI-STATE capability for both driver and receiver outputs across the entire common mode voltage range.
• Includes thermal shutdown protection that forces driver outputs into a high-impedance state during excessive power dissipation.

Applications

• Multipoint data transmission systems requiring extended common mode range.
• Industrial control networks utilizing RS485 or RS422 protocols.
• Bus interfaces allowing multiple devices to share a single transmission line.

Procurement Notes

Verify the specific ordering suffix against current TI documentation to confirm package type and temperature range. Confirm RoHS compliance status as indicated in the latest Package Option Addendum. Ensure the component meets the required operating temperature specifications for the intended application environment before procurement.

Selection Notes

Select the DS3695N for applications requiring a single-driver, single-receiver interface with robust fault protection. Consider the DS3695T variant if operation within the industrial temperature range of -40°C to +85°C is necessary. Verify that the system load impedance allows for up to 32 transceivers on the bus without exceeding unit load limits.

Part Context

The DS3695N belongs to the DS3695 family of multipoint transceivers from Texas Instruments. This series includes variants such as the DS3695T, DS3696, and DS3697, which offer similar functionality with variations in temperature ratings or additional features like repeater capabilities. The DS3695N specifically targets commercial temperature applications.

Replacement Considerations

The DS3695TN/NOPB serves as a direct replacement for applications requiring extended temperature ranges (-40°C to +85°C). Other family members like the DS3696 or DS3697 may require circuit modifications due to functional differences such as repeater inputs or additional drivers.
