74AVC4T774RSVR-NT

Overview

The SN74AVC4T774RSVR-NT is a 4-bit dual-supply bus transceiver from Texas Instruments, designed for bidirectional voltage level translation. It operates with a data rate of 380 Mb/s and supports supply voltages ranging from 0.65 V to 3.6 V. The device features independent direction control inputs referenced to the VCCA voltage. Packaged in a 16-pin UQFN (2.6x1.8 mm) format, it ensures low power consumption with an operating current of 40 uA. The component functions as a non-inverting buffer/driver with three-state outputs, suitable for high-speed digital interfaces.

Feature Summary

• Bidirectional voltage level translation between dual power supplies
• Independent direction control input for each channel
• Configurable voltage-level shifting capabilities
• Low quiescent current operation

Applications

• Mobile applications requiring low-voltage interface translation
• Consumer electronics with mixed voltage domains
• Industrial systems needing signal level conversion
• Computing equipment interfacing different logic families

Procurement Notes

Verify the exact suffix 'NT' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with the required UQFN-16 footprint and thermal characteristics during PCB layout. Cross-reference the datasheet revision to validate electrical parameters such as propagation delay and leakage currents for your specific operating conditions.

Selection Notes

Select this component when bidirectional translation between two distinct voltage domains is required without external control complexity. The independent DIR pin allows flexible routing control per channel. Consider the 380 Mb/s data rate limit and the 0.65 V minimum supply voltage when designing for ultra-low-power or high-speed signaling environments compared to standard 5V-tolerant alternatives.

Part Context

This part belongs to the SN74AVC4T774 family of dual-supply bus transceivers. It serves as a bridge between different voltage levels in complex digital systems. The RSVR package variant indicates a specific surface-mount configuration optimized for automated assembly. It is functionally similar to other AXC/AVC series translators but tailored for specific speed and voltage requirements.

Replacement Considerations

SN74AXC4T774RSVR is a related variant within the same product family offering similar functionality with potentially updated electrical characteristics. Verify pinout compatibility and voltage range specifications before substitution. Other members of the AVC4T774 series may serve as functional equivalents if package and performance metrics align with design constraints.
