DS26LS31C Quad High Speed Differential Line Driver 5.25V 35mA IC DIP-16

Description

DS26LS31C Quad High Speed Differential Line Driver 5.25V 35mA IC DIP-16 The DS26LS31C is a quad differential line driver designed to transmit high-speed digital signals with excellent noise immunity. It converts standard TTL logic levels into differential outputs, making it ideal for reliable communication over twisted-pair or balanced transmission lines. This IC is widely used in data communication systems where signal integrity and resistance to electromagnetic interference are critical. With four independent driver channels integrated into a single DIP-16 package, the DS26LS31C offers a compact and efficient solution for multi-line data transmission. Its through-hole package makes it easy to integrate into prototyping boards and industrial PCBs. The device is commonly paired with differential line receivers in RS-422 and RS-485 style communication systems, ensuring stable performance in electrically noisy environments. Features: Quad differential line driver. High-speed signal transmission. Differential balanced outputs. Strong noise immunity. TTL-compatible inputs. Designed for long-distance data communication.
