SN75453BP

Buffers, Drivers, Receivers, Transceivers Overview

The SN75453BP is a dual peripheral driver manufactured by Texas Instruments, designed for high-current and high-speed switching applications within TTL logic systems. It features an open-collector output configuration with two independent drivers. The device operates on a standard supply voltage range of 4.75 V to 5.25 V and supports low-level output currents up to 300 mA. It is housed in an 8-pin PDIP package and functions within a temperature range of 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'BP' indicates the through-hole PDIP-8 package variant rather than surface-mount options. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments, as availability may vary by region and production cycle.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel driver with open-collector outputs is required for interfacing TTL logic with higher current loads. Ensure the application environment remains within the specified 0°C to +70°C operating temperature range and that the power supply voltage stays strictly between 4.75 V and 5.25 V.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx545xB series of dual peripheral drivers from Texas Instruments. These devices are functionally interchangeable with earlier SN75450 and SN75450A series components while offering improved latch-up protection. The SN75453B specifically implements NAND gate logic internally connected to NPN output transistors.
