Frequently Asked Questions
What interface standard does the SN75112N support?
The SN75112N is designed to comply with the V.35 interface standard, which is commonly used for high-speed synchronous serial communications between data terminal equipment and data circuit-terminating equipment. It provides differential outputs suitable for balanced line driving as specified by the V.35 standard.
What is the maximum data rate supported by the SN75112N line driver?
The SN75112N supports data transmission rates up to 100 kbps over balanced differential lines as required by the V.35 standard. Its high-drive output and low output impedance ensure signal integrity across the full specified data rate range in industrial and telecommunications environments.
What does the gated input feature mean on the SN75112N?
The gated input characteristic means the SN75112N includes an enable/disable control pin for each driver channel, allowing the output to be selectively activated or deactivated. This is useful in bus-sharing or multiplexed communication systems where multiple drivers share a common line and only one driver should be active at a time.
What package type is the SN75112N available in?
The SN75112N is available in a 14-pin Dual-In-Line Package (DIP-14), which is a through-hole package suitable for traditional PCB assembly. This package type makes it easy to prototype on breadboards and integrate into legacy or industrial designs that require robust mechanical connections.
What are typical applications for the SN75112N?
Typical applications for the SN75112N include V.35 modems, DSU/CSU data service units, serial communication multiplexers, industrial data links, and data acquisition systems. Its dual-channel configuration and gated control make it well-suited for any application requiring reliable V.35-compliant differential line driving with selective output control.
