SN74AVC4T245DYYR

Translators, Level Shifters Overview

The SN74AVC4T245DYYR is a 4-bit dual-supply noninverting bus transceiver in a 16-pin SOT package. It supports configurable voltage translation between VCCA and VCCB rails ranging from 1.2V to 3.6V. The device enables asynchronous bidirectional data transfer with maximum rates up to 380Mbps for 1.8V to 3.3V translation. It features I/Os tolerant to 4.6V, partial power-down mode via Ioff, and high ESD protection exceeding 8000V HBM.

Translators, Level Shifters Feature Summary

• Fully configurable dual-rail design allows independent operation of ports across the full 1.2V to 3.6V supply range
• I/O pins are 4.6V tolerant, enabling safe interfacing with higher voltage nodes
• Ioff circuitry disables outputs to prevent backflow current during partial power-down states
• ESD protection exceeds JESD 22 standards with 8000V Human-Body Model tolerance

Translators, Level Shifters Applications

• Personal electronics
• Industrial systems
• Enterprise infrastructure
• Telecommunications equipment

Translators, Level Shifters Procurement Notes

Verify the DYY suffix corresponds to the SOT-23-THIN-16 package configuration. Confirm that the specific revision level matches the required thermal characteristics. Ensure input circuits on unused ports are tied to valid logic levels to prevent excessive current consumption. Validate that the operating temperature range aligns with system requirements.

Translators, Level Shifters Selection Notes

Select this component when interfacing buses with different voltage domains within the 1.2V to 3.6V range. The SOT package offers a compact footprint suitable for space-constrained designs. Ensure the DIR and OE control signals are driven by VCCA-referenced logic levels for proper functionality.

Translators, Level Shifters Part Context

This part belongs to the SN74AVC4T245 family of low-voltage level translators. The DYY suffix specifically denotes the SOT-23-THIN-16 package variant. Other variants include RGY (WQFN), PW (TSSOP), and RSV (UQFN). All share identical electrical specifications but differ in physical dimensions and thermal properties.

Translators, Level Shifters Replacement Considerations

SN74AVC4T245RSVR (UQFN-16) and SN74AVC4T245RGYR (WQFN-16) offer equivalent electrical performance with alternative package footprints.
