74LVCH32245ABF8

Overview

The Renesas 74LVCH32245ABF8 is a 32-bit bus transceiver utilizing advanced dual metal CMOS technology. It operates within a voltage range of 2.7V to 3.6V and supports bidirectional data transfer with three-state outputs. The device provides an output current capability of 24mA for both high and low states. It features typical output skew of less than 250ps and robust ESD protection exceeding 2000V per MIL-STD-883 Method 3015. Designed for surface mount applications, it functions effectively across an operating temperature range of -40°C to 85°C.

Feature Summary

• Configurable as four independent 8-bit or one 32-bit transceiver via Direction and Output Enable controls
• High-speed operation with low power consumption using advanced dual metal CMOS technology
• Robust electrostatic discharge protection exceeding 2000V under standard testing conditions

Applications

• Asynchronous memory systems requiring high-speed data transfer
• Clock drivers for synchronous circuits
• Bus-oriented communications interfaces

Procurement Notes

Verify the specific suffix BF8 against official Renesas documentation to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with your system's voltage levels and thermal requirements before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the ordering information matches the exact electrical characteristics required for your design.

Selection Notes

Select this component when a 32-bit wide data path is necessary with configurable segmentation capabilities. It is suitable for designs requiring low skew and high ESD immunity in a compact BGA package. Consider the 2.7V to 3.6V supply range to ensure compatibility with 3.3V logic families. Evaluate the 24mA drive strength against load requirements to determine if additional buffering is needed.

Part Context

This device belongs to the LVCH (Low Voltage CMOS) family, designed for high-speed, low-power applications in portable and industrial electronics. The 74LVCH series offers performance improvements over older LVC variants while maintaining pin compatibility. The ABF8 suffix indicates a specific 96-pin CABGA package configuration used by Renesas for this density level.

Replacement Considerations

Direct substitutes include SN74LVC32245ZKER from Texas Instruments and 74LVCH32245AEC:55 from Nexperia. Verify pinout compatibility and electrical parameters such as VCC range and drive strength before substitution.
