The 32 mA source and 64 mA sink drive capability is enough to fan out to multiple 3.3V CMOS loads or drive a single TTL input with healthy margin. ## 32 mA source, 64 mA sink — what the drive numbers actually mean The asymmetric drive reflects the 74LVTH family's BiCMOS output stage: the NPN pull-down sinks more current than the CMOS pull-up sources. In practice, this means the buffer can drive a terminated transmission line on the low side without struggle, but the high-side is limited. If you need to drive a 50-ohm backplane trace at 3.3V, the 32 mA source will hit its limit at roughly a 100-ohm Thevenin termination — check the DC load line. For ordinary CMOS fan-out (a few pF per gate), both edges are fine up to 100 MHz or so. The 3-state output lets multiple buffers share a bus; just mind the turn-on/turn-off timing if you're doing hot-swap or bidirectional muxing. For the BOM cost engineer, this means no single-source risk from obsolescence — the 74LVTH family is a mature 3.3V logic line with broad second-source overlap from TI and others. The package is the standard narrow 14-SOIC, so the footprint matches any SOIC-14 buffer or line driver in the same supply class. ## 14-SOIC — the footprint that fits The 14-SOIC package measures 3.90 mm body width — the narrow variant, not the wide SOIC-14 that some logic families use. If your board already has a land pattern for a 74LVC125A or 74AHCT125 in SOIC-14, this part drops in without a layout change.","metaTitle":"SN74LVTH125D 74LVTH Buffer, 3-State, 14-SOIC, 2.7V–3.6V","metaDescription":"TI SN74LVTH125D quad non-inverting buffer with 3-state outputs, 32/64 mA drive, -40°C to 85°C, active production.","metaKeywords":null},"attributes":{"series":"74LVTH","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74LVTH","Package":"Tube","Logic Type":"Buffer, Non-Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 3.6V","Number of Elements":"4","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"14-SOIC","Current - Output High, Low":"32mA, 64mA","Number of Bits per Element":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.26","priceTiers":[{"qty":1,"price":"$1.26000","currency":"USD"},{"qty":10,"price":"$1.12600","currency":"USD"},{"qty":25,"price":"$1.06840","currency":"USD"},{"qty":100,"price":"$0.87770","currency":"USD"},{"qty":250,"price":"$0.82044","currency":"USD"},{"qty":500,"price":"$0.72504","currency":"USD"},{"qty":1000,"price":"$0.57240","currency":"USD"},{"qty":2500,"price":"$0.54000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b82f0d8fb8a0d26307a71357eee01aa0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74LVTH125D/alternatives.json"},"ai":{"faq":[{"question":"What is the equivalent of SN74LVTH125D?","answer":"The closest functional equivalent in the same 74LVTH family is the SN74LVTH16245ADGVR, but that is a 16-bit transceiver (2 elements x 8 bits) in a different package, not a direct pin-for-pin replacement.
