SN74AVC4T774RGYR

Translators, Level Shifters Overview

The SN74AVC4T774RGYR is a 4-bit dual-supply bus transceiver from the Texas Instruments AVC logic series, housed in a 16-VQFN package. It supports bidirectional voltage level translation between VCCA and VCCB rails ranging from 1.1 V to 3.6 V. The device features configurable voltage translation with three-state outputs and independent direction control inputs. Key electrical parameters include a data rate of 380 Mb/s and a propagation delay of 2.4 ns. It operates within a temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Bidirectional voltage level translation between two independently configurable power supply rails
• Independent direction control inputs for managing signal flow
• Three-state outputs to prevent bus contention

Translators, Level Shifters Applications

• Connecting low-voltage processors to higher-voltage peripheral buses
• Memory interface translation in embedded systems
• General-purpose bidirectional level shifting in mixed-voltage digital circuits

Translators, Level Shifters Procurement Notes

Verify the specific suffix RGYR confirms the 16-VQFN (4x3.5 mm) package with exposed pad. Confirm RoHS compliance status and Moisture Sensitivity Level (MSL 2) requirements for your assembly process. Ensure the design accounts for the independent direction control pin functionality distinct from standard fixed-direction translators.

Translators, Level Shifters Selection Notes

Select this component when independent direction control is required for bidirectional traffic on a 4-bit bus. It is suitable for applications needing voltage translation between any combination of 1.1 V to 3.6 V rails. Compare against non-controlled variants like the SN74AVC4T774 if direction pins are not needed to simplify PCB layout.

Translators, Level Shifters Part Context

This part belongs to the SN74AVC4T774 family of high-speed bus transceivers. It shares core specifications with other package variants such as the RSVR (UQFN-16) and PWR (TSSOP-16), differing primarily in physical footprint and thermal characteristics while maintaining identical electrical performance.
