SN74AUC34RGYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC34RGYR is a hex buffer and line driver from Texas Instruments' AUC logic family, housed in a 14-VQFN package. It operates within a supply voltage range of 0.8 V to 2.7 V, supporting mixed-mode signal operation with 3.6-V I/O tolerance. The device features push-pull outputs capable of sourcing and sinking 9 mA. Key electrical characteristics include a propagation delay of 2.8 ns at 1.8 V. It functions reliably across an industrial temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports partial-power-down mode via Ioff circuitry to prevent excessive current draw during standby.
• Enables mixed-mode signal operations by tolerating voltages up to 3.6 V on inputs while powered at lower levels.
• Optimized for low-voltage 1.8-V applications with high-speed performance suitable for data bus buffering.

Buffers, Drivers, Receivers, Transceivers Applications

• Buffering data buses in portable battery-powered devices
• Driving loads in mixed-signal environments requiring level translation support
• System-level power management circuits utilizing partial-power-down states

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity and packaging configuration. Confirm that the component meets RoHS compliance standards for your target market. Ensure the procurement channel provides valid traceability documentation. Check for moisture sensitivity level requirements regarding storage and reflow soldering profiles before assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring hex buffering with low voltage operation between 0.8 V and 2.7 V. It is appropriate for applications needing 3.6-V I/O tolerance to interface with higher voltage peripherals. Consider the 14-VQFN package for space-constrained PCB layouts. Evaluate the 9 mA drive strength against load capacitance requirements to ensure signal integrity.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AUCxx series of ultra-low voltage CMOS logic devices. The AUC family is designed for modern portable electronics demanding minimal power consumption and high speed. The RGYR suffix indicates a 14-lead Very Thin Quad Flat No-lead (VQFN) package with an exposed thermal pad, optimized for surface-mount assembly.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct functional equivalents may include other hex buffers from the same AUC family with compatible pinouts. Verify that any substitute maintains the 0.8 V to 2.7 V operating range and 3.6-V I/O tolerance. Ensure the replacement package matches the 14-VQFN footprint and thermal characteristics for direct board integration.
