SN74LVC1T45DCKT

Translators, Level Shifters Overview

The SN74LVC1T45DCKT is a single-channel, non-inverting bidirectional bus transceiver from the Texas Instruments SN74LVC1T45 series. It facilitates voltage level translation between two independent power domains, supporting VCCA and VCCB supply voltages ranging from 1.65V to 5.5V. The device features three-state outputs and accepts CMOS or LVTTL input levels. Packaged in an SC-70-6 surface-mount format, it operates within a temperature range of -40°C to +85°C. Propagation delay is specified at 17.7ns.

Translators, Level Shifters Feature Summary

• Bidirectional voltage level translation between dual independent power rails
• Direction control via dedicated DIR pin for A-to-B or B-to-A data flow
• Ioff support enabling partial power-down mode to prevent backflow current
• ESD protection exceeding JESD 22 requirements with latch-up performance over 100mA

Translators, Level Shifters Applications

• Interfacing mixed-voltage logic systems
• Post-board-level signal translation
• Bidirectional buffering across different voltage domains

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'T' indicates cut-tape packaging rather than reel configuration. Confirm RoHS compliance status through official documentation. Ensure the SC-70-6 footprint matches the design layout. Validate that the 17.7ns propagation delay meets system timing requirements under intended operating conditions.

Translators, Level Shifters Selection Notes

Select this component when a single channel of bidirectional level shifting is required between 1.65V and 5.5V domains. The SC-70-6 package suits space-constrained designs. Verify that the DIR pin logic aligns with the VCCA reference voltage. Consider Ioff functionality if local power-down states are necessary to isolate inactive voltage buses.

Translators, Level Shifters Part Context

This part belongs to the SN74LVC1T45 family of single-bit dual-supply bus transceivers. It shares core electrical characteristics with variants like the SN74LVC1T45DCKR but differs in packaging type. The DCK suffix denotes the SC-70 package, while the T suffix specifies the tape-and-reel quantity format.

Translators, Level Shifters Replacement Considerations

SN74LVC1T45DCKR offers identical electrical specifications in a standard reel format.
