SN74AVCBH164245KR

Translators, Level Shifters Overview

The SN74AVCBH164245KR is a 16-bit dual-supply bus transceiver with configurable voltage translation and 3-state outputs, housed in a VFBGA package. It operates within a supply voltage range of 1.4 V to 3.6 V for both ports. Propagation delay ranges from 1.3 ns to 8.5 ns depending on voltage conditions. The device supports partial-power-down mode via Ioff circuitry and features dynamic output control (DOC) for noise reduction.

Translators, Level Shifters Feature Summary

• Fully configurable dual-rail design allows each port to operate over the full 1.4-V to 3.6-V power-supply range
• Dynamic Output Control (DOC) circuitry dynamically changes output impedance to reduce noise without speed degradation
• Active bus-hold circuitry eliminates the need for external pullup/pulldown resistors on data inputs
• Ioff support enables partial-power-down operation by disabling outputs to prevent damaging current backflow

Translators, Level Shifters Applications

• Asynchronous communication between data buses operating at different voltage levels
• Mixed-voltage-mode data communications utilizing overvoltage-tolerant inputs/outputs
• Universal low-voltage bidirectional translation between 1.5-V, 1.8-V, 2.5-V, and 3.3-V nodes

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix KR corresponds to the VFBGA package configuration as documented in the manufacturer's ordering information. Confirm that the component meets the required operating temperature range of -40°C to 85°C for your application environment. Ensure compatibility with the specified tape and reel packaging format if automated assembly is utilized.

Translators, Level Shifters FAQ

How does the device handle floating data inputs?

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level, eliminating the need for external pullup or pulldown resistors.

What happens if either VCC input is at GND?

If either VCC input is at GND, both ports are placed in the high-impedance state to ensure proper isolation and protection.
