Surface-mount 8-SOIC, 0.154\" body width, 3.90 mm. The BDR suffix means Tape & Reel or Cut Tape — standard for pick-and-place. No special footprint; it's the same 8-SOIC as a thousand other parts. If you're hand-replacing one on a board, a fine-tip iron and some flux will do it. No end-of-life notice, no last-time-buy window. It's a mature, standard-product peripheral driver that TI has made for decades. Availability through independent distribution is steady; we source and quote it to order against an RFQ. Current pricing and stock levels are confirmed at quote time — no automated numbers here, but the part is not hard to find.","metaTitle":"SN75451BDR Peripheral Driver, 300mA, 8-SOIC, Active","metaDescription":"Texas Instruments SN75451BDR dual peripheral driver, open-collector outputs, 300 mA sink per channel, 5 V supply, 8-SOIC.

That's the per-channel rating; the total package dissipation limits how many channels you can run at that level simultaneously."},{"question":"What does SN75451BDR do?","answer":"It is a dual peripheral driver that takes a logic-level input and switches a higher-current load (relay, lamp, solenoid) to ground via an open-collector output. It's a buffer between a 5 V logic controller and a load that needs more current than a logic gate can supply."},{"question":"What is the pinout of SN75451BDR?","answer":"The part comes in an 8-SOIC package. Pin 1 is the input for driver A, pin 2 is the input for driver B, pins 3 and 6 are the corresponding open-collector outputs, pin 4 is ground, pin 5 is the common output for the second driver (shared with pin 6 internally), pin 7 is VCC, and pin 8 is the common output for the first driver (shared with pin 3 internally).
