What are the key features of SN751178NE4?
- Dual transmitter/receiver with tri-state outputs supporting both EIA-422-B and EIA-485-A differential bus standards
- Differential Schmitt trigger receiver inputs provide superior noise immunity on long-run industrial cabling
- 16-pin PDIP package enables straightforward prototype and retrofit installation in through-hole PCB designs
What is SN751178NE4 used for?
The SN751178NE4 is used in industrial automation and process control systems to interface microcontrollers or FPGAs with RS-485 multi-drop networks spanning up to 1200 meters at data rates up to 10 Mbps. Its dual-channel architecture allows simultaneous transmit and receive paths within a single IC, reducing BOM and board space in PLC I/O modules and serial communication adapters. The tristatable receivers support multi-node bus topologies where many transceivers share a single differential pair.

Frequently Asked Questions
Which differential bus standards does the SN751178NE4 support, and what cable distances can it drive?
The SN751178NE4 supports EIA-422-B, TIA-422-B, EIA-485-A, TIA-485-A, V.10, and V.11 differential standards. RS-485 networks using this transceiver can span up to 1200 meters at lower data rates such as 100 kbps, or operate at up to 10 Mbps over shorter cable runs of 10-15 meters, making it versatile for both long-haul slow links and short-run high-speed buses.
How do the tristatable receivers on the SN751178NE4 benefit multi-node RS-485 bus designs?
Tri-state receivers allow the SN751178NE4 to electrically disconnect from the RS-485 bus when the output-enable pin is de-asserted, presenting a high-impedance load of less than 12 kOhm. This lets up to 32 unit loads share a single differential pair without bus loading degrading signal integrity, which is the basis of standard RS-485 multi-drop networks used in MODBUS RTU and similar industrial protocols.
Why choose SN751178NE4 in a 16-pin PDIP rather than an equivalent SMD transceiver for a new RS-485 design?
The 16-pin PDIP (R-PDIP-T16) package is preferred when rapid prototyping, field repair, or breadboard evaluation is needed, since through-hole parts can be inserted and removed without soldering tools. For retrofit of existing through-hole boards, the PDIP footprint avoids PCB rework. If the application eventually moves to SMT production, equivalent SOIC-packaged transceivers from the same TI family offer a direct pin-for-pin replacement at the same 16-pin count.
