SN75453BPG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN75453BPG4 is a dual high-current peripheral driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and delivers a low-level output current of 300 mA. The device features two input lines and two inverting output lines, housed in an 8-pin DIP package with a pitch of 0.300 inches (7.62 mm). It functions reliably across an operating temperature range of 0°C to +70°C, with a maximum power dissipation of 725 mW and a propagation delay of 25 ns.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant during procurement, as the SN75453B series includes both SOIC-8 (e.g., BDR) and DIP-8 (e.g., BPG4) configurations. Confirm that the selected component matches the required mounting style and pinout dimensions for your PCB design. Ensure the operating environment stays within the specified 0°C to +70°C thermal limits to maintain performance integrity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when dual-channel high-current sinking capability is necessary for peripheral loads. The inverting nature of the drivers must align with the system's logical requirements. Consider the physical footprint constraints, choosing between the compact SOIC-8 or the traditional DIP-8 based on assembly methods. Verify that the 5V supply tolerance and thermal dissipation characteristics suit the target application's power budget.
