SN75454BPSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN75454BPSR is a dual high-current peripheral driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.75V to 5.25V and supports an operating temperature range of 0°C to 70°C. The device features two independent drivers with open-collector outputs capable of sinking up to 300mA per channel. It utilizes an 8-pin Small Outline Integrated Circuit (SOIC) package with a width of 5.30mm. The component is RoHS compliant and designed for TTL logic systems.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PSR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 8-SOIC package dimensions align with the target PCB footprint. Ensure the commercial grade temperature rating meets the operational environmental requirements of the final application.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when dual-channel high-current sinking capability is required for peripheral devices. It serves as a direct replacement for older SN75450 series parts in compatible designs. Consider the SOIC package constraints and thermal dissipation characteristics relative to the expected load current during continuous operation.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN7545xB family of peripheral drivers, which includes AND, NAND, OR, and NOR gate configurations. These devices are engineered to replace legacy SN75450 series components while offering improved latch-up protection. The family provides flexible circuit design options for driving various peripheral loads directly from TTL logic sources.
