74LVCH32245ABF

Overview

The Renesas 74LVCH32245ABF is a low-voltage CMOS octal bus transceiver designed for asynchronous communication between data buses. It operates with a supply voltage range of 1.2V to 3.6V and features three-state outputs. The device includes an output enable input and a direction control input to manage data flow. It is housed in a BGA package suitable for surface-mount applications.

Feature Summary

• Supports low-voltage operation from 1.2V to 3.6V
• Provides three-state outputs for bus isolation
• Features independent direction control for each byte

Applications

• Asynchronous communication between data buses
• Memory and memory mapping
• Clock drivers

Procurement Notes

Verify the specific suffix 'BF8' or 'ABF' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure the component meets the required operating temperature range and voltage specifications for the target design before procurement.

Selection Notes

Select this component for designs requiring bidirectional data transfer at low voltages. Consider the package type and pin count relative to board space constraints. Verify that the logic levels are compatible with the connected microcontrollers or memory devices.

Part Context

This part belongs to the 74LVCH series of low-voltage CMOS logic devices. It is functionally similar to other octal bus transceivers but optimized for lower power consumption and wider voltage ranges compared to standard 5V logic families.

Replacement Considerations

Check for direct pin-to-pin replacements within the same 74LVCH family. Verify electrical characteristics such as propagation delay and drive strength when substituting with parts from other manufacturers.
