74AVC1T1022GUX

Overview

The Nexperia 74AVC1T1022GUX is a translating 1-to-4 fan-out buffer designed for clock distribution and voltage level translation. It features dual independent supplies, VCC(A) and VCC(B), each ranging from 0.8 V to 3.6 V. The device includes one data input (A), four outputs (two referenced to VCC(A) and two to VCC(B)), and an active-low output enable (OE). It supports maximum data rates up to 380 Mbit/s for translations between 1.8 V and 3.3 V. The component operates within a temperature range of -40 °C to +125 °C and utilizes Schmitt trigger inputs for noise immunity.

Feature Summary

• Dual supply architecture allowing independent VCC(A) and VCC(B) voltages between 0.8 V and 3.6 V
• Maximum data rate of 380 Mbit/s for high-speed translation applications
• Integrated IOFF circuitry prevents damaging backflow current during power-down states
• Schmitt trigger inputs provide tolerance for slow rise and fall times

Applications

• Clock distribution networks requiring signal buffering and translation
• Voltage level shifting between low-voltage logic families (e.g., 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V)
• Systems requiring isolated output enable control with pull-down resistors

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature rating. The 'GU' designation corresponds to the XQFN10 package (SOT1160-1). Confirm that the required operating temperature range matches the specified -40 °C to +125 °C limit before finalizing procurement.

Selection Notes

Select this component when a single-input, four-output buffer with simultaneous voltage translation is required. Ensure the design accommodates the dual-supply configuration, as VCC(A) and VCC(B) must be independently powered. Verify that the load capacitance requirements align with the dynamic characteristics provided in the datasheet tables for the target voltage levels.

Part Context

This device belongs to the Nexperia AVC logic family, which focuses on advanced voltage translation and buffering solutions. The 74AVC1T1022 specifically addresses the need for fan-out buffers that can drive multiple loads across different voltage domains while maintaining signal integrity through Schmitt trigger action and robust ESD protection.

Replacement Considerations

Direct functional replacements include other 1-to-4 translating fan-out buffers from the same family, such as the 74AVC1T1022DP (TSSOP10 package variant). Cross-family substitution requires verifying pin compatibility, supply voltage ranges, and propagation delay specifications.
