74AVC1T1004DPJ

Overview

The Nexperia 74AVC1T1004DPJ is a translating 1-to-4 fan-out buffer designed for clock distribution and voltage translation. It features dual independent supplies, VCC(A) and VCC(B), each ranging from 0.8 V to 3.6 V. The device accepts one data input (A) referenced to VCC(A) and provides four outputs (Yn) referenced to VCC(B). It supports maximum data rates up to 380 Mbit/s during translation between 1.8 V and 3.3 V. The component includes Schmitt trigger inputs, an active LOW output enable (OE), and IOFF circuitry to prevent backflow current during power-down. It operates within a temperature range of -40 °C to +125 °C.

Feature Summary

• Dual supply voltage range: VCC(A) and VCC(B) independently adjustable from 0.8 V to 3.6 V
• High-speed performance with maximum data rates reaching 380 Mbit/s at ≥ 1.8 V to 3.3 V translation
• Integrated IOFF circuitry disables outputs to prevent damaging backflow current when powered down
• Schmitt trigger action on all inputs ensures tolerance for slower rise and fall times

Applications

• Clock distribution networks requiring signal buffering
• Voltage level translation between different logic domains (e.g., 0.8 V to 3.3 V)
• Multi-voltage bus systems utilizing single-input to multiple-output signal routing

Procurement Notes

Verify the package type SOT552-1 (TSSOP10) matches the design footprint. Confirm that the DPJ suffix corresponds to the specific reel or tape configuration required by assembly equipment. Ensure supply voltages remain within the 0.8 V to 3.6 V limits for both VCC(A) and VCC(B) pins to maintain JEDEC compliance.

Selection Notes

Select this component when a single source signal must drive four distinct loads across different voltage levels. The dual-supply architecture allows flexible translation between any combination of 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V. Consider the propagation delay characteristics, which vary based on the specific VCC(A) and VCC(B) settings and load capacitance, when designing high-speed timing paths.

Part Context

This device belongs to the 74AVC series, characterized by Advanced Very-low-voltage CMOS technology. It is part of Nexperia's portfolio of translating buffers designed to facilitate interface connections between low-voltage components. The 1-to-4 fan-out topology distinguishes it from simple inverters or non-translating buffers, offering integrated level shifting capabilities in a compact TSSOP10 package.

Replacement Considerations

The 74AVC1T1004GU is a pin-compatible alternative housed in a DHVQFN10 package. Both devices share identical electrical specifications and functionality. Verify that the target PCB layout accommodates the physical dimensions of the replacement package variant.
