SN75452BD

Buffers, Drivers, Receivers, Transceivers Overview

The SN75452BD is a dual high-current peripheral driver manufactured by Texas Instruments, designed for TTL logic systems. It features two non-inverting channels with open-collector outputs capable of sourcing up to 300 mA at low levels and sinking 100 µA at high levels. The device operates within a supply voltage range of 4.75 V to 5.25 V and draws a typical operating current of 56 mA. It is housed in an 8-SOIC surface-mount package and supports a commercial operating temperature range from 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides dual high-current peripheral driving capability with open-collector outputs suitable for various load types.
• Features diode-clamped inputs to simplify circuit design and ensure compatibility with standard TTL logic signals.
• Designed with latch-up protection to maintain functionality under high current conditions without damage.

Buffers, Drivers, Receivers, Transceivers Applications

• Driving high-current peripheral loads in TTL-based digital systems
• Interface circuits requiring high-sink current capacity for external components
• General-purpose peripheral drivers where open-collector output flexibility is required

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as Texas Instruments may offer different tape-and-reel or tube packaging options for the SN75452 series. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability can vary based on production cycles and regional stock levels.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require robust peripheral driving with high sink current capabilities. Ensure the application voltage remains within the specified 4.75 V to 5.25 V range. Consider the open-collector output nature for level shifting or driving non-standard logic loads, and verify thermal dissipation requirements given the 725 mW power dissipation rating in the SOIC-8 package.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN7545xB family of dual peripheral drivers, which are functionally interchangeable with earlier SN75450 series devices. The SN75452B specifically provides non-inverting logic functions, distinguishing it from other variants like the SN75451B (inverting) or SN75453B (OR gate). It is part of Texas Instruments' legacy logic portfolio maintained for industrial and embedded applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN75452BDR serves as a direct reel-packaged alternative. SN75452BPSR offers the same functionality in a wider SOIC-8 variant. For pin-compatible replacements, consider SN75452BDG4 or SN75452BDE4, ensuring the replacement matches the required package width and thermal characteristics.
