Each of the two elements drives two bits, giving four independent open-collector outputs. The operating temperature range is 0°C to 70°C. ## 300 mA sink — what it means for relay and solenoid selection The 300 mA current-sink rating per output sets the load ceiling: a 5 V relay coil drawing 150 mA leaves 50% headroom, but a 24 V relay with a 400 mA coil is out of range. For solenoid valves in the 200 mA to 250 mA range, the SN75463P works with a flyback diode across the load. The open-collector output pulls low when the input is high, so the load connects between the positive supply and the output pin. No internal clamp diode is specified — add an external one (1N400x or similar) for inductive kickback protection. ## Package and footprint — through-hole for prototyping and legacy boards The 8-DIP (0.300\", 7.62 mm) through-hole package with the 8-PDIP supplier package fits standard prototyping boards and sockets. No thermal pad or exposed paddle — the plastic DIP relies on lead-frame conduction. ## Lifecycle and sourcing posture The SN75463P carries an Active lifecycle status and is ROHS3 compliant. For BOM planning, this means the part remains a valid line-item for new production without imminent obsolescence risk.","metaTitle":"SN75463P Peripheral Driver, 300mA Sink, 8-DIP, Active","metaDescription":"SN75463P peripheral driver IC, 2 elements x 2 bits, 300mA sink per output, 4.75V-5.25V supply, 0°C-70°C, 8-DIP.

It uses a single transistor per output rather than a Darlington pair, so the saturation voltage will be lower than a Darlington at the same current, but the gain is also lower."},{"question":"What is the equivalent of SN75463P?","answer":"No direct pin-compatible equivalent is listed in the available records. The SN74LS645-1N is a different logic type (transceiver, non-inverting) with 15 mA output current and 8-bit width — not a functional replacement for a 300 mA peripheral driver. For a drop-in substitute, verify the pinout and output current rating against your specific load requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN75463P","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN75463P when reusing this data.
