74HC245PW,118

74HC245PW,118 is the tape-and-reel TSSOP-20 ordering code for the Nexperia 74HC245 octal bus transceiver, listed as Active on the Nexperia product page (ordering code 935183570118). Eight transceiver channels with three-state outputs move a byte-wide bus in either direction under a direction-control pin, with HC-family input thresholds of 1.5 V minimum high level at a 2 V supply, 3.15 V at 4.5 V and 4.2 V at 6 V, and quiescent current of 8 µA maximum at 25 °C with a 6 V supply, inputs tied to the rails and no output load (80 µA maximum over -40 °C to +85 °C, 160 µA maximum over -40 °C to +125 °C). The selection point is byte-width bus buffering in a 20-pin TSSOP: data-bus driving, memory interfacing and board-to-board byte links where eight discrete buffers would waste area and routing. Selection advice: the PW,118 code is the TSSOP-20 body on a 13-inch reel. The same transceiver is also ordered in the wider SO-20 body as 74HC245D,653 (7-inch reel, listed Active in the same Nexperia package table; the tube-packed ,652 code is a separate ordering code that is already withdrawn, and is not this variant) - it shares the datasheet and the electrical characteristics with this code and differs only in body, land pattern and thermal resistance, so confirm the body letter against the layout before ordering either code; designs on 3.3 V rails should also compare the 74LVC245A (also listed), whose family is specified around lower-voltage operation. Parameters verified against the Nexperia 74HC245 datasheet Rev. 9 static characteristics and the product-page package table.
