The 3:4 input-to-output ratio means three supply inputs are mapped across four outputs, a topology designed for the dual-voltage sequencing requirements of PCMCIA and CardBus applications. ## On-resistance and thermal budget for the slot With a typical Rds(on) of 95 mOhm per channel, the conduction loss at 1 A is under 100 mW per output — manageable in the 24-HTSSOP package if the exposed pad is soldered to a copper plane. No direct pin-compatible replacement has been officially designated in the available records. For existing BOM lines, procurement must turn to independent distribution and surplus inventory channels.","metaTitle":"TPS2223PWP PCMCIA Power Switch, 95mOhm, Obsolete","metaDescription":"Texas Instruments TPS2223PWP PCMCIA switch, 4 outputs, 1A, 95mOhm Rds(on), 3.3V/5V load, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Features":"Status Flag","Interface":"Serial","Input Type":"-","Output Type":"-","Switch Type":"PCMCIA Switch","Rds On (Typ)":"95mOhm","Mounting Type":"Surface Mount","Package / Case":"24-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","Product Status":"Obsolete","Voltage - Load":"3.3V, 5V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"4","Base Product Number":"TPS222","Output Configuration":"High Side","Ratio - Input:Output":"3:4","Operating Temperature":"-40°C~85°C(TA)","Current - Output (Max)":"1A","Supplier Device Package":"24-HTSSOP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fd8477305e59097cdd3e981440f521e7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2223PWP/alternatives.json"},"ai":{"faq":[{"question":"Is TPS2223PWP obsolete?","answer":"It is no longer manufactured and must be sourced from surplus or broker inventory."},{"question":"What is the difference between TPS2223PWP and TPS2223?","answer":"The TPS2223PWP suffix indicates the specific package variant — 24-TSSOP with exposed pad (HTSSOP) in tube packaging.
