SN74AVC4T245PW-P

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC4T245PW is a 4-bit dual-supply noninverting bus transceiver with configurable voltage-level shifting and 3-state outputs. It operates with VCCA and VCCB ranging from 1.2V to 3.6V, supporting bidirectional translation between nodes such as 1.2V, 1.8V, 2.5V, and 3.3V. The device achieves maximum data rates of up to 380Mbps during 1.8V to 3.3V translation. Control inputs are referenced to VCCA, and the I/Os tolerate voltages up to 4.6V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Fully configurable dual-rail design allows each port to operate over the full 1.2V to 3.6V power-supply range
• I/Os are 4.6V tolerant for interfacing with higher voltage systems
• Ioff supports partial power-down mode operation to prevent backflow current
• Control input logic levels are referenced to the VCCA supply voltage

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package suffix against the manufacturer's official documentation to ensure correct physical dimensions and pinout compatibility. Confirm that the ordering information matches the required tape-and-reel or cut-tape format for your assembly process. Cross-reference the datasheet revision history to ensure all electrical characteristics align with your design requirements before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when asynchronous communication between two data buses operating at different voltage levels is required. Ensure the system utilizes push-pull drivers connected to the data I/Os to maximize performance. Verify that the control pins are supplied by VCCA and that unused data inputs are held at a valid logic level to prevent excess current consumption.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AVC4T245 family of low-voltage bus transceivers manufactured by Texas Instruments. It is designed for high-speed applications requiring universal low-voltage bidirectional translation. The PW suffix indicates a 16-pin Thin Shrink Small-Outline Package (TSSOP) suitable for surface-mount technology applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include SN74AVC4T245D, SN74AVC4T245RGYR, and SN74AVC4T245RSVR. These variants share identical electrical specifications but differ in package type. Verify pinout compatibility and thermal resistance values when substituting.
