Package and board integration
The TXU0102DCUR comes in an 8-VFSOP (0.091", 2.30 mm width) package, also specified as the 8-VSSOP supplier device package. The 0.5 mm pin pitch demands a controlled impedance trace width on the outer layers — a 4-layer board is not required for fan-out, but the narrow pitch means the via-in-pad or microvia approach keeps the signal path short for the 200 Mbps edge rate. Surface-mount assembly with Tape & Reel (TR) or Cut Tape (CT) packaging — the reel quantity suits volume pick-and-place; the cut tape works for prototype or low-volume runs. No exposed thermal pad, so the footprint is a simple eight-pad layout with the keep-out zone per the TI recommended land pattern.
What the 200 Mbps data rate means in a real signal chain
Rated at 200 Mbps, the TXU0102DCUR handles typical SPI, I2C fast-mode-plus, or UART clock rates without timing margin issues. The unidirectional channel type means it translates signals in one direction only — use two devices for bidirectional buses like I2C, or a single TXU0102DCUR for a unidirectional SPI MOSI line. The tri-state output lets multiple translators share a bus line when the output enable is pulled low. The dual supply range (1.08 V to 5.5 V on both VCCA and VCCB) covers the common logic families: 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V. No external level-shifting resistors needed — the internal pass-gate architecture drives the output rail directly. The -40°C to 125°C operating temperature range qualifies it for under-hood or industrial enclosure use where ambient temperature cycles wide.
