Applications
The SN75158P is used to drive RS-422 and V.11 balanced differential communication links in industrial automation networks, process control systems, and CNC machine interfaces where long cable runs require noise-immune differential signaling. It is commonly deployed in point-to-point serial data links between PLCs, motor drives, and remote I/O modules in factory environments with high electrical noise. The device also serves in multi-drop RS-422 bus systems for building automation, instrumentation, and data acquisition equipment requiring reliable data transmission over distances exceeding 100 meters.

Frequently Asked Questions
What communication standards does the SN75158P comply with?
The SN75158P complies with the EIA-422-B (also known as TIA-422-B and ITU V.11) balanced differential interface standard. This standard specifies balanced transmission for serial data at speeds up to 10 Mbps over cable lengths up to 1200 meters (at lower data rates), making the SN75158P suitable for robust industrial and telecommunications serial communication links.
How many differential channels does the SN75158P provide and what is the output configuration?
The SN75158P provides two independent differential line driver channels (dual driver). Each channel produces a balanced differential output with both true (A) and complement (B) output signals, resulting in four output pins total for two communication channels. This dual-channel configuration is ideal for half-duplex or full-duplex RS-422 applications using a single 8-pin DIP package.
What package does the SN75158P use and is it through-hole or surface mount?
The SN75158P is available in an 8-pin plastic DIP (PDIP) through-hole package, identified by JESD-30 code R-PDIP-T8. The through-hole DIP format is easy to prototype with, ideal for legacy system repairs, and provides mechanical robustness in vibration-prone industrial environments. Lead-free versions are available with Pb-free code marked as Yes and JESD-609 code e4.
What data rate can the SN75158P achieve and over what cable length?
As an EIA-422-B compliant driver, the SN75158P supports data rates up to 10 Mbps at short cable distances and up to approximately 100 kbps at cable lengths near 1200 meters. The achievable data rate decreases as cable length increases due to cable capacitance. For most industrial applications at 115.2 kbps, cable runs of several hundred meters are practical with appropriate twisted-pair cable.
What is a common alternative to the SN75158P for surface mount designs?
For surface mount designs requiring the same EIA-422-B dual differential driver function, the SN75ALS194 or SN65LVDS100 series offer compatible functionality in SOIC packages. The SN75158 (without the P suffix) is also available in SOIC-8 format. For RS-485 multi-point bus applications (where receivers are also needed), the SN75176 transceiver is a common alternative combining driver and receiver in one package.
