74AVC4T774RGYRG4

Overview

The SN74AVC4T774RGYRG4 is a four-bit dual-supply bus transceiver from Texas Instruments, designed for asynchronous communication between two independent buses. It operates with supply voltages ranging from 1.2 V to 3.6 V on both ports and supports data rates up to 380 Mb/s. The device features low propagation delay of 2.4 ns and is housed in a 16-pin UQFN package. It functions as a voltage level translator with three-state outputs.

Feature Summary

• Supports bidirectional data transmission between independent buses using dual power supplies
• Configurable voltage translation capabilities across wide input/output ranges
• Provides high-speed signal integrity with low propagation delay characteristics

Applications

• Asynchronous communication between different voltage domains
• Voltage level translation in portable systems
• High-speed data bus interfacing

Procurement Notes

Verify the specific suffix RGYRG4 against the manufacturer datasheet to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with required operating temperatures and voltage levels before integration into the design.

Selection Notes

Select this component when designing systems requiring bidirectional level shifting between disparate voltage rails. Consider the 16-pin UQFN footprint for space-constrained layouts and verify that the 380 Mb/s speed meets the system's timing requirements.

Part Context

This part belongs to the SN74AVC4T774 series of dual-supply bus transceivers. It is engineered for applications needing reliable data transfer between logic families or subsystems operating at different voltage potentials without direct electrical connection.
