Product details

Octal bus transceiver for mixed-voltage backplanes

The NXP 74LV245DB,118 is an octal (8-bit) bus transceiver with non-inverting logic and 3-state outputs, designed for bidirectional data flow between two buses. Its 1V to 5.5V supply range makes it a practical choice for level-shifting between low-voltage cores (1.8V, 2.5V) and legacy 3.3V or 5V peripherals. Each of the eight channels can sink or source 16 mA, enough to drive a short backplane trace or a handful of CMOS loads.

Wide supply and extended temperature

The supply range from 1V to 5.5V covers the common logic rails in mixed-voltage designs.

Active lifecycle and compliance

It is ROHS3 compliant, which clears the restriction-of-hazardous-substances requirement for EU-market equipment and most global OEM specs.

Frequently asked questions

What is the difference between 74LV245DB,118 and 74LVC245A?

The 74LV245 operates from 1V to 5.5V with 16 mA drive, while the 74LVC245A typically runs on 1.65V to 3.6V and offers 24 mA drive. The 74LVC245A also includes 5V-tolerant inputs. If your bus runs at 5V or needs the wider supply range, the 74LV245 is the correct choice. For higher drive or 5V-tolerant inputs at 3.3V, the 74LVC245A is a better fit.

Can I use 74LV245DB,118 for level shifting?

Yes. The 1V to 5.5V supply range lets the part translate between low-voltage logic (1.8V, 2.5V) and higher-voltage buses (3.3V, 5V). Connect the VCC pin to the supply rail of the side that drives the direction-control pin. The outputs are 3-state, so you can tristate the bus when the transceiver is not selected.
