SN75452BDR

Buffers, Drivers, Receivers, Transceivers Overview

The SN75452BDR is a dual high-current peripheral driver manufactured by Texas Instruments, designed for TTL logic systems. It features two non-inverting inputs and outputs housed in an SOIC-8 package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a low-level output current of 300 mA. It functions reliably across a temperature range of 0°C to +70°C with a propagation delay of 35 ns and a quiescent current of 56 mA.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'D' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the selected variant matches the required operating temperature range and package dimensions for your PCB layout.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing TTL logic with high-current peripherals requiring significant sink capability. The open-collector architecture allows for voltage level shifting beyond standard logic levels. Consider the SOIC-8 footprint constraints and thermal dissipation requirements associated with the 300 mA output current during peak operation.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx545xB series of dual peripheral drivers from Texas Instruments. It serves as a functional replacement for older SN75450 series components while offering improved speed and latch-up immunity. The device integrates internal connections between logic gates and NPN output transistors for efficient peripheral control.
