74AVC1T1022DPJ

Overview

The Nexperia 74AVC1T1022DPJ is a translating 1-to-4 fan-out buffer designed for clock distribution applications. It features dual independent supplies, VCC(A) and VCC(B), supporting voltage levels from 0.8 V to 3.6 V. The device provides one data input (A) and four outputs: two referenced to VCC(A) (1Yn) and two to VCC(B) (2Yn). It includes an active LOW output enable (OE) with internal pull-down resistors. Key electrical parameters include a maximum data rate of 380 Mbit/s at ≥1.8 V translation, propagation delays ranging from 0.9 ns to 23 ns depending on supply conditions, and ESD protection exceeding 8000 V HBM. It operates within a temperature range of -40 °C to +125 °C.

Feature Summary

• Translating 1-to-4 fan-out buffer with dual supplies (VCC(A)/VCC_B) for voltage translation between 0.8 V and 3.6 V
• Maximum data rates up to 380 Mbit/s for translations ≥1.8 V to 3.3 V
• Active LOW output enable (OE) with integrated pull-down resistors
• Schmitt trigger inputs tolerant of slow rise/fall times; IOFF circuitry prevents backflow current when powered down

Applications

• Clock distribution networks requiring voltage level translation
• Low voltage translation between standard logic levels (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V)
• Systems requiring isolated fanned-out signals with different reference voltages

Procurement Notes

Verify the ordering suffix 'DPJ' against official Nexperia documentation. The provided datasheet lists 'DP' as TSSOP10 (SOT552-1) and 'GU' as XQFN10 (SOT1160-1). Confirm if 'J' indicates a specific tape-and-reel packaging variant or marking code change, as this affects physical handling and PCB footprint verification.

Selection Notes

Select this component when a single input signal must be distributed to four outputs across two different voltage domains. Ensure VCC(A) and VCC(B) are independently supplied within the 0.8 V to 3.6 V range. Verify that the required propagation delay fits the system timing constraints, as delays vary significantly based on the delta between VCC(A) and VCC(B). Check power dissipation limits (250 mW max) relative to ambient temperature derating curves.

Part Context

The 74AVC1T1022 belongs to the Nexperia AVC family of translating buffers. The DPJ designation refers to the specific package and reel configuration of the base 74AVC1T1022 model. While the core functionality remains identical to other suffixes like DP or GU, the suffix determines the mechanical form factor (TSSOP10 for DP) and shipping quantity/packaging type.

Replacement Considerations

Direct pin-compatible replacements within the same family include 74AVC1T1022DP (TSSOP10) and 74AVC1T1022GU (XQFN10). Ensure the substitute matches the required package outline (SOT552-1 for TSSOP10) and thermal characteristics.
