Supply-voltage flexibility and the translation decision
The MAX3370EXK+T: That VCCA floor of 1.65 V means it handles sub-1.8 V logic — 1.8 V, 1.5 V, even 1.2 V if the core rail holds — without an external bias.
Data rate and output drive
Rated for 3 Mbps, the part handles UART, SPI, and I2C traffic at standard bus speeds. The bidirectional channel with open-drain and push-pull output options means it can drive an I2C bus (open-drain, requires pull-ups) or a push-pull SPI signal line without extra glue. At 3 Mbps the propagation delay is low enough that a 1 MHz SPI clock with a 50% duty cycle has margin for setup-and-hold on the far side, but the trace capacitance on both VCCA and VCCB rails should stay under 50 pF to avoid edge-rate degradation.
Package and board-fit for the SC-70-5
Housed in a 5-lead SC-70 (also known as SOT-353), the MAX3370EXK+T occupies roughly 2.0 mm × 2.1 mm of board area. The supplier device package is SC-70-5; the footprint matches the standard JEDEC MO-203 variation.
Temperature grade and operating range
The Power Supply Decoupling feature noted in the spec means the part integrates internal decoupling capacitance; still, a 0.1 µF ceramic cap within 2 mm of each supply pin is standard practice to keep the internal bias stable during fast edges.
