What this 8-bit transceiver does on the bus
The Nexperia 74LVC2245ADB,118 is an 8-bit non-inverting transceiver with 3-state outputs, built on the 74LVC low-voltage CMOS logic family. It handles bidirectional data flow between two independent buses, with a direction control (DIR) pin steering the data path and an output enable (OE) pin putting the outputs into high-impedance state for bus isolation. Each of the eight channels can source or sink 12mA, which is enough to drive a handful of standard CMOS inputs on a short backplane or a ribbon cable segment without needing a buffer.
Supply voltage and temperature — the BOM-fit check
The 1.2V to 3.6V supply range is the headline spec that decides whether this part replaces a dedicated level shifter in your BOM. At 1.2V it works with the lowest modern core voltages; at 3.6V it tolerates a 3.3V rail with margin for transients. Because the part is specified over the full temperature range, you do not need to derate the output drive or worry about propagation delay drift outside the datasheet limits when the board runs hot — a common trap with commercial-grade logic parts.
Package and footprint for the rework bench
The 20-SSOP package (0.209-inch body width, 5.30mm) is a standard shrink small-outline footprint. The 0.65mm pin pitch is fine for hand-soldering with a fine tip, but the narrow body means the part sits close to adjacent components — check clearance if you are retrofitting into a layout originally designed for a wider SOIC-20.
