SN751730DE4

Drivers, Receivers, Transceivers Overview

The SN751730DE4 is a triple line driver/receiver manufactured by Texas Instruments, designed to meet IBM System 360/370 interface specifications. It operates on a single 5-V supply with a voltage range of 4.75 V to 5.25 V and supports data rates up to 4.5 Mb/s. The device features three uncommitted emitter-follower outputs for party-line operation and includes internal short-circuit protection. Propagation delay ranges from 6.5 ns to 18.5 ns for drivers and 7.5 ns to 19.5 ns for receivers. It is housed in a 16-pin SOIC (D) package and functions within an operating temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Uncommitted emitter-follower output structure enables wired-OR logic for party-line applications
• Internal clamping network provides driver output short-circuit protection
• Driver inputs and receiver outputs are compatible with standard TTL logic levels

Drivers, Receivers, Transceivers Applications

• IBM System 360/370 input/output interfaces
• Coaxial cable or twisted pair terminated line driving
• TTL-compatible logic gating during power-up and power-down sequences

Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix 'E4' indicates compliance with RoHS standards and absence of halogenated flame retardants. Confirm the package designation matches the required footprint. Ensure the operating temperature range aligns with system requirements. Cross-reference the manufacturer part number against current availability lists to confirm active production status.

Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing with IBM 360/370 systems requiring 4.5-Mb/s operation. Choose the SOIC package for surface-mount assembly needs. Verify that the single 5-V supply capability fits the system power architecture. Consider the uncommitted outputs if wired-OR functionality is necessary for the specific bus topology.

Drivers, Receivers, Transceivers Part Context

The SN751730DE4 belongs to the SN751730 family of triple line driver/receivers. It is specifically engineered for high-speed digital communication in legacy mainframe environments. The 'DE4' suffix denotes a specific tape-and-reel or tube packaging variant compliant with environmental directives. This part serves as a bridge between TTL logic and differential transmission lines.
