74LCXH32245G

Overview

The SN74LCXH32245G is a low voltage 32-bit bidirectional transceiver with 5V tolerant inputs and outputs, featuring bushold functionality. It operates within a supply voltage range of 2.0V to 3.6V and supports an operating temperature from -40°C to +85°C. The device utilizes a 96-ball Fine-Pitch Ball Grid Array (FBGA) package (BGA96A). Key electrical parameters include a maximum propagation delay of 4.5 ns at VCC = 3.3V, a maximum quiescent supply current of 20 µA, and output drive capabilities of ±24 mA at VCC = 3.0V.

Feature Summary

• Features 5V tolerant inputs and outputs for interfacing between low voltage and 5V signal environments.
• Incorporates bushold on inputs to eliminate the need for external pull-up or pull-down resistors.
• Supports live insertion and withdrawal operations when configured correctly.
• Utilizes patented noise and EMI reduction circuitry for improved signal integrity.

Applications

• Bus-oriented applications requiring bi-directional data transfer
• Memory bus architectures
• High-density digital systems

Procurement Notes

Verify that the ordering code suffix 'G' corresponds to tray packaging as specified in the datasheet. Confirm the package type is BGA96A. Ensure compatibility with the required supply voltage range of 2.3V to 3.6V for optimal performance. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component for applications requiring 32-bit wide data buses with high-speed bidirectional transfer. Consider the bushold feature if minimizing external components is a priority. Ensure the PCB layout accommodates the FBGA package dimensions. Verify that the system power supply remains within the recommended operating conditions to maintain specified electrical characteristics.

Part Context

This device belongs to the LCX family of low-voltage CMOS logic devices. It is designed to provide high-speed operation while maintaining low power dissipation. The part number indicates a specific variant with tray packaging. It serves as a bridge between different voltage domains in complex digital systems.

Replacement Considerations

Check for equivalent parts from other manufacturers offering similar 32-bit bus transceivers with 5V tolerance and bushold features. Ensure pinout compatibility and electrical specifications match before substitution.

FAQ

What is the function of the bushhold feature?

Bushold eliminates the need for external pull-up or pull-down resistors by holding unused inputs in a defined state.

How does the device support live insertion?

It supports live insertion/withdrawal, but OE should be tied to VCC through a pull-up resistor to ensure high-impedance state during power-up or down.
