Key Features
- Dual independent supply rails for Port A and Port B enable seamless bidirectional voltage-level translation between any two logic standards (1.2V to 3.6V)
- 8-bit wide bidirectional bus transceiver with common direction and output-enable controls, reducing external logic in mixed-voltage system buses
- Low 15 pF load capacitance and LVC-family switching speed provide high signal integrity suitable for fast parallel bus interfaces
- Three-state outputs allow multiple transceivers to share a common bus without conflict, ideal for multi-master embedded and SoC designs
Applications
The SN74LVC8T245PWR is used in processor-to-peripheral interfaces where different supply voltages must communicate, such as connecting a 1.8V microcontroller bus to 3.3V memory or FPGA I/O banks. It is also employed in industrial data acquisition systems and communication backplanes requiring reliable 8-bit parallel data transfer across voltage domains. Its tape-and-reel packaging supports high-volume SMT production for automotive, computing, and telecom applications.

Frequently Asked Questions
What voltage levels does the SN74LVC8T245PWR support for level translation?
The SN74LVC8T245PWR supports independent supply voltages for Port A (VCCA) and Port B (VCCB) in the range of 1.2V to 3.6V, enabling bidirectional translation between any two logic levels within that range, including 1.8V, 2.5V, and 3.3V standards.
Is data transfer bidirectional on the SN74LVC8T245PWR?
Yes, the SN74LVC8T245PWR is a bidirectional transceiver controlled by a common direction pin (DIR). Setting DIR high routes data from Port A to Port B; setting it low reverses the direction, allowing full duplex-capable bus communication in embedded system designs.
What package does the SN74LVC8T245PWR use and how many pins does it have?
The SN74LVC8T245PWR uses a 24-pin Small Outline (SOIC, JESD-30 code R-PDSO-G24) package, offering a compact surface-mount footprint suitable for densely populated PCBs in space-constrained applications.
Is the SN74LVC8T245PWR RoHS compliant?
Yes, the SN74LVC8T245PWR is Pb-free and RoHS compliant, designated by the JESD-609 code e4, making it appropriate for consumer electronics and industrial products sold in regulated markets globally.
What are typical applications for the SN74LVC8T245PWR?
Typical applications include voltage-level translation between microcontroller and memory interfaces, FPGA I/O expansion, backplane bus buffering, industrial sensor interfaces, and any mixed-voltage parallel data bus requiring eight-bit bidirectional signal translation.
