SN75121D TI Interface IC | | Quad Differential Line Driver, 5V

Product Overview

The SN75121D is a quad differential line driver designed by Texas Instruments (TI) to meet the requirements of high-speed data transmission in noisy environments. It features four independent differential drivers with 3-state outputs, making it ideal for balanced transmission lines. The device operates from a single 5V supply and is compatible with TTL and CMOS logic levels. Its high output impedance in the disabled state allows for multipoint bus applications. The SN75121D is offered in a 16-pin SOIC package (D suffix) and is characterized for operation from 0°C to 70°C.
