SN75452BP

Buffers, Drivers, Receivers, Transceivers Overview

The SN75452BP is a dual peripheral driver from Texas Instruments designed for high-current, high-speed switching applications within TTL logic systems. It features two non-inverting drivers with open-collector outputs capable of sourcing up to 300 mA and tolerating voltages up to 30 V. The device operates on a standard 5 V supply (4.75 V to 5.25 V) and includes diode-clamped inputs to prevent latch-up during high-current switching. It is housed in an 8-pin PDIP package and functions as a direct replacement for the SN75450 series.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'BP' indicates the plastic DIP-8 package variant when ordering. Confirm RoHS compliance status through official manufacturer documentation, as older production runs may differ. Ensure the application environment remains within the specified commercial temperature range of 0°C to 70°C. Cross-reference pinouts with current datasheets to account for any historical revisions in the SN7545xB family.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require driving inductive or capacitive loads directly without external transistors. The open-collector architecture allows flexibility in interfacing with different voltage domains up to the 30 V limit. Consider the 300 mA continuous current rating against peak load requirements to ensure thermal stability. Verify that the input logic levels align with the system's TTL source capabilities.

Buffers, Drivers, Receivers, Transceivers Part Context

The SN75452BP belongs to the SN7545xB family of dual peripheral drivers, which also includes AND, OR, and NOR gate variants (SN75451B, SN75453B, SN75454B). This family was engineered to replace earlier SN75450 series parts while offering improved speed and robustness against latch-up conditions. The 'B' designation typically denotes enhanced performance characteristics over the original generation.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the maximum output voltage the SN75452BP can handle?

The open-collector outputs are rated to withstand voltages up to 30 V.

Does the SN75452BP have internal pull-up resistors?

No, the outputs are open-collector type, requiring external pull-up components if a high logic state is needed.

How does the SN75452BP compare to the SN75450?

It is functionally interchangeable with the SN75450 but offers higher speed and guaranteed latch-up immunity at 300 mA output current.
