74AVC4T245GUZ

Overview

The Nexperia 74AVC4T245GUZ is a 4-bit dual supply translating transceiver with configurable voltage translation and 3-state outputs. It enables bidirectional level translation between VCC(A) and VCC(B), both ranging from 0.8 V to 3.6 V. The device supports maximum data rates up to 380 Mbit/s depending on the voltage translation range. It features IOFF circuitry for partial power-down applications, preventing damaging backflow current. ESD protection exceeds 8000 V (HBM Class 3B) and 1000 V (CDM Class C3). Operating temperature ranges from -40 °C to +125 °C.

Feature Summary

• Configurable bidirectional voltage translation between two independent low-voltage nodes
• IOFF circuitry prevents damaging backflow current during partial power-down
• High ESD protection exceeding 8000 V HBM and 1000 V CDM standards
• Suspend mode isolates buses when either supply rail is at GND

Applications

• Translating between low voltage nodes such as 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V
• Partial power-down applications requiring isolation of powered-down ports
• Bidirectional bus interfacing in systems with mixed voltage domains

Procurement Notes

Verify the package type matches the XQFN16 (SOT1161-1) specification. Confirm the suffix 'Z' indicates lead-free and halogen-free compliance per Nexperia definitions. Ensure the operating temperature range requirement aligns with the -40 °C to +125 °C rating. Check that input/output voltage levels do not exceed the 3.6 V absolute maximum ratings.

Selection Notes

Select this component when bidirectional translation between dual supplies within the 0.8 V to 3.6 V range is required. It is suitable for applications needing high ESD robustness and partial power-down capabilities. Consider the XQFN16 package dimensions if space constraints are critical. Verify data rate requirements against the specific voltage translation configuration.

Part Context

This device belongs to the 74AVC series of translating transceivers. It shares functional similarities with other 4-bit variants like the 74AVC4T245D or 74AVC4T245PW but differs in package form factor. The GUZ variant specifically utilizes the extremely thin quad flat package without leads.

Replacement Considerations

Direct replacements include other 74AVC4T245 variants with different packages, such as 74AVC4T245D (SO16) or 74AVC4T245PW (TSSOP16), provided footprint compatibility is addressed.
