SN74ALVC164245KR

Translators, Level Shifters Overview

The SN74ALVC164245KR is a 16-bit level-shifting transceiver from the Texas Instruments ALVC series, housed in a 48-pin TSSOP package. It features dual power supplies: VCCA (2.3V to 3.6V) and VCCB (3V to 5.5V), enabling translation between 2.5V/3.3V and 3.3V/5V domains. Key electrical parameters include a maximum propagation delay of 5.8ns at 3.3V, ±24mA output drive capability, and 3-state outputs. The device operates within a temperature range of -40°C to +85°C with a quiescent current of 40µA.

Translators, Level Shifters Feature Summary

• Supports bidirectional voltage translation between 2.5V, 3.3V, and 5V logic levels via independent A and B port power rails.
• Provides high-speed data transfer with a maximum propagation delay of 5.8ns.
• Features robust latch-up protection exceeding 250mA per JESD 17 standards.

Translators, Level Shifters Applications

• Mobile phones

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'KR' against the official datasheet to confirm the exact tape-and-reel quantity and moisture sensitivity level. Ensure the selected package variant matches the PCB footprint requirements for the 48-pin TSSOP configuration.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems requiring simultaneous conversion between 2.5V and 3.3V or 3.3V and 5V logic families. The ALVC series offers lower power consumption compared to older LVC technologies while maintaining high speed suitable for modern embedded applications.

Translators, Level Shifters Part Context

This device belongs to the SN74ALVC164245 family of 16-bit level-shifting transceivers. It is designed for low-voltage applications and serves as a bridge for mixed-voltage system architectures, ensuring signal integrity across different power domains without requiring external components.

Translators, Level Shifters Replacement Considerations

Check for SN74ALVC164245DGGR or SN74ALVC164245DGG if alternative packaging or reel quantities are required. Verify pinout compatibility before substituting with other 16-bit transceivers.
