74LVC1T45Z6-7

Overview

The 74LVC1T45Z6-7 is a single-bit dual-supply translating transceiver with 3-state outputs manufactured by Diodes Incorporated. It facilitates logic level translation between voltage domains ranging from 1.65V to 5.5V. The device features a direction control pin (DIR) referenced to VCCA, allowing data transfer from A to B when high, or B to A when low. It operates within an ambient temperature range of -40°C to +125°C and utilizes the SOT563 package.

Feature Summary

• Bidirectional voltage translation across independent power domains
• Direction control via dedicated DIR pin referenced to VCCA
• IOFF feature prevents backflow current during partial power-down
• High noise immunity with typical hysteresis

Applications

• Voltage level translation between different logic types
• Power-down signal isolation for disconnected voltage domains
• Portable electronics such as cell phones and tablets
• Computer peripherals including hard drives and routers

Procurement Notes

Verify the specific Z6 suffix corresponds to the SOT563 package configuration required for your layout. Confirm that the tape and reel packaging quantity aligns with your production needs. Ensure compatibility with RoHS and halogen-free environmental standards before finalizing procurement orders.

Selection Notes

Select this component when interfacing two distinct voltage domains requiring a single bidirectional channel. The SOT563 package offers a compact footprint suitable for space-constrained designs. Ensure the DIR pin is properly biased to establish the desired data flow direction between the A and B ports.

Part Context

This part belongs to the 74LVC1T45 family of single-bit translating transceivers. The Z6 suffix specifically designates the SOT563 surface-mount package variant. Other variants in the series include DW for SOT363 and FZ4 for X2-DFN1410-6 packages, providing options for different board space requirements.

Replacement Considerations

Direct package replacements within the same family include 74LVC1T45DW-7 (SOT363), 74LVC1T45W6-7 (SOT26), and 74LVC1T45FW4-7 (X2-DFN1010-6). Verify pinout compatibility and thermal resistance differences when substituting packages.
