SN74AVCA164245KR

Translators, Level Shifters Overview

The SN74AVCA164245KR is a 16-bit dual-supply bus transceiver with configurable voltage translation and three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 1.4 V to 3.6 V for both ports. The device supports asynchronous communication between data buses, transmitting data from the A bus to the B bus or vice versa based on the direction-control input. It features overvoltage-tolerant inputs/outputs allowing mixed-voltage-mode data communications and DOC circuitry that dynamically changes output impedance to reduce noise without speed degradation.

Translators, Level Shifters Feature Summary

• Dual-supply architecture allows universal low-voltage bidirectional translation between any 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes
• DOC circuitry dynamically adjusts output impedance during transitions to drive loads effectively while reducing noise
• Overvoltage-tolerant I/Os enable safe mixed-voltage-mode data communications across different power domains
• IOFF circuitry supports partial-power-down mode by disabling outputs to prevent damaging current backflow

Translators, Level Shifters Applications

• Asynchronous communication between data buses in mixed-voltage systems
• Universal low-voltage bidirectional translation between 1.5-V, 1.8-V, 2.5-V, and 3.3-V nodes
• Partial-power-down applications requiring high-impedance state isolation

Translators, Level Shifters Procurement Notes

Verify the specific package type (VFBGA-ZQL) and marking code (WA4245) against the datasheet ordering information. Confirm the operating temperature range (-40°C to 85°C) matches system requirements. Ensure ESD protection ratings meet JESD standards for the intended environment. Check for RoHS compliance status if required by project specifications.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring flexible voltage translation between multiple low-voltage logic families. The dual-rail design accommodates varying supply voltages on each port independently. Consider the DOC feature for applications sensitive to signal integrity and noise reduction during high-speed transitions. Verify control input referencing to VCCA for proper logic level interpretation.

Translators, Level Shifters Part Context

This device belongs to the Widebus family of bus transceivers from Texas Instruments. It is part of the SN74AVCA series, designed for high-performance asynchronous data transmission. The KR suffix indicates the VFBGA-ZQL package variant. It shares functional similarities with other AVC devices but offers specific voltage translation capabilities suited for modern low-voltage digital interfaces.

Translators, Level Shifters Replacement Considerations

Direct substitutes include SN74AVCA164245GR (TSSOP) and SN74AVCA164245VR (TVSOP) for pin-compatible alternatives in different packages. For similar functionality in alternative packages, consider SN74AVCB164245 variants. Verify package dimensions and thermal characteristics when substituting.
