SN75452BPSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN75452BPSR is a dual high-current peripheral driver manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a low-level output current of 300 mA. The device features non-inverting logic with two input and two output lines, exhibiting a propagation delay of 35 ns. Designed for industrial environments, it functions reliably between 0°C and +70°C, drawing a typical operating supply current of 56 mA.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PSR' confirms the SOIC-8 tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation, as environmental declarations may vary by production batch. Ensure the component meets the required operating temperature range for the intended application environment before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when dual-channel high-current sinking is required for TTL-compatible logic interfaces. It serves as a direct replacement for older SN75450 series devices while offering improved speed characteristics. Consider the 8-SOIC package constraints and thermal dissipation capabilities relative to the expected load current and ambient temperature conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN7545xB family of dual peripheral drivers designed for high-current, high-speed switching applications. It is functionally compatible with previous generations like the SN75450 but provides enhanced performance metrics. The device integrates diode-clamped inputs to protect against transient voltages and ensure robust operation in noisy digital environments.
