Key Features
- Dual-supply voltage translation between 1.2V–3.6V (VCCA) and 1.65V–5.5V (VCCB) for flexible mixed-voltage interfacing
- 8-bit bidirectional data bus with direction control (DIR) and output enable (OE) pins
- High-speed operation with low propagation delay for demanding digital logic designs
- 24mA output drive capability supporting bus-hold and capacitive load applications
- Available in compact TSSOP-24 (PWR) package for space-constrained PCB layouts
Applications
The SN74AVC8T245PWR is widely used in mixed-voltage digital systems where logic-level translation is required between microcontrollers, FPGAs, and peripheral devices operating at different supply voltages. It is commonly deployed in memory interfaces, communication buses (SPI, I2C, parallel), and industrial control boards that bridge 1.8V or 2.5V logic to 3.3V or 5V systems. Its bidirectional capability and tri-state outputs also make it ideal for shared bus architectures and data buffering in embedded and IoT designs.

Frequently Asked Questions
What voltage levels does the SN74AVC8T245PWR support for logic translation?
The SN74AVC8T245PWR supports VCCA from 1.2V to 3.6V and VCCB from 1.65V to 5.5V, enabling bidirectional logic-level translation between systems such as 1.8V, 2.5V, 3.3V, and 5V. This makes it suitable for interfacing microcontrollers, FPGAs, and legacy 5V peripherals in mixed-voltage designs.
How do I control the direction and enable state of the SN74AVC8T245PWR?
The SN74AVC8T245PWR uses a DIR pin to select data flow direction: when DIR is HIGH, data flows from A to B; when LOW, data flows from B to A. The active-low OE (output enable) pin disables all outputs and places them in a high-impedance tri-state when pulled HIGH, allowing safe bus sharing with other drivers.
What is the package type for SN74AVC8T245PWR and what are its dimensions?
The SN74AVC8T245PWR comes in a 24-pin TSSOP (Thin Shrink Small Outline Package) with a 0.65mm pin pitch. The 'PWR' suffix denotes the TSSOP-24 package variant, which is compact and suitable for high-density PCB designs. Tape-and-reel packaging is available for automated assembly.
Can the SN74AVC8T245PWR be used as a replacement for SN74LVC8T245?
The SN74AVC8T245PWR is closely related to the SN74LVC8T245 and shares the same 8-bit dual-supply transceiver architecture and pinout. The primary difference is the AVC series supports a lower minimum VCCA of 1.2V versus 1.65V for LVC, making AVC the better choice for 1.2V or 1.5V logic-level systems.
