SN75473DR

Buffers, Drivers, Receivers, Transceivers Overview

The SN75473DR is a dual peripheral driver manufactured by Texas Instruments, designed for RS-232 and RS-485 interface applications. It operates within a supply voltage range of 4.75 V to 5.25 V and supports data rates up to 10 Mb/s. The device features two drivers with non-inverting logic and is housed in a 16-SOIC surface-mount package. It functions reliably across an operating temperature range of 0°C to +70°C, drawing a typical supply current of 70 mA.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DR' confirms the tape-and-reel packaging format upon ordering. Confirm RoHS compliance status as indicated in the official datasheet documentation. Ensure the selected variant matches the required SOIC-16 footprint and thermal specifications for the target application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when dual differential driving capability is required for half-duplex or full-duplex communication lines. Compare against single-driver alternatives if only one channel is needed. Verify that the 10 Mb/s maximum data rate aligns with system timing requirements and that the 5 V supply voltage is compatible with the host power architecture.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN7547x series of peripheral drivers from Texas Instruments. It serves as a complementary solution to receiver-only ICs like the SN75173, providing the transmit side of the interface link. The DR suffix denotes a specific reel-based packaging option suitable for automated surface-mount assembly processes.
