74AVCB164245ZRDR

Overview

The SN74AVCB164245ZRDR is a 16-bit dual-supply bus transceiver from the Texas Instruments Widebus family, housed in a 54-pin Microstar Junior package. It supports voltage translation between 1.2V and 3.6V rails with configurable conversion capabilities. The device features three-state outputs and bidirectional data transmission controlled by a DIR input. Key electrical parameters include a maximum propagation delay of 3.1 ns at 30 pF load, output currents of ±12 mA, and an operating temperature range of -40°C to +85°C.

Feature Summary

• DOC circuitry dynamically adjusts output impedance to reduce noise
• Configurable voltage translation for mixed-voltage systems
• Bidirectional data transfer between A and B buses

Applications

• High-speed data bus interfaces
• Voltage level translation between different power domains
• Portable electronic devices requiring low power consumption

Procurement Notes

Verify the specific suffix ZRDR corresponds to the 54-pin Microstar Junior package when sourcing. Confirm that the order includes the correct reel configuration if mass production is intended. Ensure compatibility with the target PCB footprint dimensions of 8x5.5 mm before finalizing procurement orders.

Selection Notes

Select this component for applications requiring wide voltage range translation and high-speed performance. The DOC circuitry makes it suitable for noise-sensitive environments. Compare pin counts and package types against alternatives like the GR or VR variants to ensure mechanical fit within the design constraints.

Part Context

This part belongs to the AVC series of bus transceivers designed for low-voltage operations. It complements other Widebus family members by offering 16-bit width in a compact form factor. The device integrates advanced drive control to maintain signal integrity across varying load conditions.

Replacement Considerations

SN74AVCB164245GR and SN74AVCB164245GRE4 are alternative packages for the same logical function. Verify package compatibility as these use TSSOP-48 instead of Microstar Junior.
