Description:

Lot of 10x Texas Instruments SN75158P dual differential line driver ICs in 8-pin DIP package. These classic RS-422 / V.11 line drivers provide two TTL-compatible balanced outputs for driving twisted-pair lines with high current and low power dissipation. New old stock in tubes, clean leads and never soldered – ideal for repairing industrial controls, serial links and retro-computing hardware.

Modern uses:

- Repairing or extending RS-422 / balanced serial links on vintage CNC, PLC and industrial control boards

- Building robust differential links between microcontrollers and remote sensors or motor drives

- Replacing older 75158 / SN75158 line driver chips in legacy equipment

- Educational projects demonstrating differential signaling vs single-ended TTL

Compatibility note:

SN75158P is a standard 5 V dual differential line driver designed to meet ANSI EIA/TIA-422-B and ITU V.11 specs, with TTL inputs and balanced line outputs. It runs from a single 5 V supply (approx. 4.75–5.25 V) and is characterized for 0…+70 °C operation. It is generally drop-in compatible with other 75158-family drivers in PDIP-8, but always confirm pinout, supply voltage and interface standard (RS-422/V.11) against your original circuit before installation, especially in long-cable or industrial environments.
