What are the key features of SN75157P-P2?
- Dual RS-422/RS-485 differential line receiver with wide common-mode range of -7V to +7V for robust industrial noise immunity
- High data rate capability up to 10 Mbps enabling reliable serial communication over long twisted-pair cables up to 300 meters
- 14-pin DIP through-hole package providing easy breadboard prototyping and rugged PCB mounting in industrial environments
What is SN75157P-P2 used for?
SN75157P-P2 receives balanced differential signals in RS-422 and RS-485 serial communication networks used in industrial automation, PLCs, and building control systems. It is used as the receive-side component in half-duplex or full-duplex multi-drop networks connecting up to 32 nodes over twisted-pair cable. The wide common-mode input range makes it resilient to ground potential differences between nodes in long-distance industrial data acquisition systems.

Frequently Asked Questions
What is the maximum data rate of SN75157P-P2 and over what cable length can it reliably receive RS-422 signals?
SN75157P-P2 supports data rates up to 10 Mbps on short cables. On longer twisted-pair cables, the maximum rate decreases due to cable capacitance; over 300 meters of 120-ohm twisted pair, reliable reception at 100 kbps is achievable per RS-422 standard guidelines. Proper 120-ohm termination at the receiver end is required to prevent reflections.
How many SN75157P-P2 receivers can be connected on a single RS-485 bus alongside drivers?
RS-485 allows up to 32 standard unit load devices on a single bus. SN75157P-P2 presents 1 unit load at its differential input, so up to 32 SN75157P-P2 receivers can share a single RS-485 bus segment. With low-load variants or repeaters, larger networks of 256 nodes or more can be constructed for multi-drop industrial installations.
Does the SN75157P-P2 DIP-14 package allow direct replacement of older RS-422 receiver ICs in legacy systems?
Yes, the SN75157P-P2 is pin-compatible with industry-standard 14-pin DIP RS-422 dual receiver footprints. Operating from a single 5V supply with a common-mode range of -7V to +7V, it serves as a drop-in replacement for older differential line receiver ICs in legacy industrial control systems requiring RS-422 or RS-485 balanced data reception.
