SN75453BPSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN75453BPSR is a dual peripheral driver manufactured by Texas Instruments, designed for high-current and high-speed switching applications. It operates within a supply voltage range of 4.75V to 5.25V and supports an operating temperature range of 0°C to 70°C. The device features two elements with two bits per element, utilizing open-collector outputs capable of sourcing up to 300mA in the low state and sinking 100µA in the high state. Packaged in an 8-SOIC surface-mount format with a width of 5.30mm, it is supplied in cut tape or reel configurations.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PSR' confirms the 8-SOIC surface-mount package and tape-and-reel shipping method. Confirm the 'B' grade designation aligns with the required commercial temperature range of 0°C to 70°C. Ensure compatibility with standard 5V logic systems given the specified 4.75V to 5.25V supply voltage constraints.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when dual-channel high-current drive capability is required without integrated receivers. Compare against the SN75452BPSR if identical electrical characteristics are needed but different packaging or ordering suffixes are preferred. Verify that the open-collector output type meets the load requirements, as it lacks internal pull-up resistors.
