SN75471D

Buffers, Drivers, Receivers, Transceivers Overview

The SN75471D is a dual peripheral driver from Texas Instruments, housed in an 8-pin SOIC package. It features two independent drivers with TTL-compatible diode-clamped inputs and operates on a standard supply voltage of 4.75 V to 5.25 V. The device supports high-voltage outputs up to 70 V and can handle continuous collector currents of 400 mA, with peak currents reaching 500 mA. Characterized for operation between 0°C and 70°C, it provides medium-speed switching capabilities suitable for various logic buffer and power driver applications.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and material finish. Confirm RoHS compliance status and moisture sensitivity level ratings before procurement. Ensure the selected variant matches the required operating temperature range and packaging quantity specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when higher breakdown voltages are required compared to series SN75451B or SN75461. Note that these drivers offer slightly slower switching speeds than the SN75451B series but maintain similar limits to the SN75461 series. Consider the power dissipation requirements relative to the ambient temperature for proper thermal management.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN75471 through SN75473 series of dual peripheral drivers. While functionally interchangeable with older series like SN75451B and SN75461, it is specifically designed for systems requiring higher breakdown voltages. The series includes variants with AND, NAND, and OR logic functions integrated into the driver structure.
