SN75112N

SN75112N Description

The SN75112N from Texas Instruments is a dual-line driver IC designed for robust signal transmission in digital communication systems. Operating within a 4.75V to 5.25V supply range, this 2/0 (2 drivers, 0 receivers) device is optimized for TTL (Transistor-Transistor Logic) compatibility, ensuring reliable interfacing in industrial and computing environments. Housed in a 14-pin DIP (Dual In-line Package), the SN75112N is suited for through-hole mounting, offering durability in legacy or high-reliability applications. Although marked as obsolete, it remains a viable choice for systems requiring stable, low-power drivers with RoHS3 compliance and REACH unaffected status.

SN75112N Features

• Dual Driver Configuration: Supports two independent TTL-compatible output channels.
• Wide Operating Voltage (4.75V–5.25V): Ensures stable performance in standard 5V logic systems.
• Industrial Temperature Range (0°C to 70°C): Reliable operation in moderate environmental conditions.
• Through-Hole Package (14-DIP): Facilitates easy integration into existing PCB designs.
• Low Power Consumption: Optimized for energy-efficient applications.
• RoHS3 Compliant & REACH Unaffected: Meets modern environmental standards despite obsolete status.

SN75112N Applications

• Legacy Computing Systems: Ideal for retrofitting or maintaining vintage computer hardware.
• Industrial Control Interfaces: Used in PLCs (Programmable Logic Controllers) and automation systems requiring TTL-level signal buffering.
• Telecommunication Equipment: Ensures signal integrity in low-speed data transmission lines.
• Test & Measurement Tools: Provides precise signal driving for diagnostic instruments.

Conclusion of SN75112N

The SN75112N is a dependable dual-line driver for applications demanding TTL-level signal integrity and through-hole reliability. While obsolete, its RoHS3 compliance, wide voltage tolerance, and robust packaging make it a pragmatic choice for legacy systems, industrial controls, and niche electronics. Engineers seeking a proven, no-frills driver for 5V logic environments will find this IC a cost-effective solution.
