74LVCH16244AX4PA

Overview

The IDT 74LVCH16244AX4PA is a 3.3V CMOS address-clock driver designed for high-speed digital systems. It functions as a buffer/driver with 1-to-4 output capability, suitable for driving memory address buses and clock signals. The device utilizes advanced dual metal CMOS technology to ensure performance and density in bus-oriented applications. It features symmetrical active-low output-enable inputs and provides true outputs. Designed for 3.3V computing systems, it supports moderate to heavy loads while maintaining speed performance through its specific output driver characteristics.

Feature Summary

• 3.3V CMOS address-clock driver with 1-to-4 output configuration
• Symmetrical active-low output-enable (OE) inputs
• True outputs with ±24mA drive capability
• Advanced dual metal CMOS technology for improved density

Applications

• 3.3V high-speed systems
• Memory address drivers
• Clock drivers
• Bus-oriented receivers and transmitters

Procurement Notes

Verify the package type against the local source description which lists 'Bulk' packaging, while cross-referencing standard industry packages like TSSOP or SSOP found in similar IDT ALVC/LVCH series datasheets. Confirm the manufacturer IDT vs Renesas post-acquisition status if sourcing from current distributors. Ensure the specific suffix X4PA matches the required pinout and electrical specifications for the target design.

Selection Notes

Select this component when a 3.3V logic family buffer is required for address or clock distribution. The 1-to-4 ratio suggests it may be part of a larger 16-bit configuration or used for specific sub-bus segments. Check that the system voltage aligns with the 3.3V nominal supply range. Consider the ±24mA output drive strength for load requirements compared to standard LVCH devices.

Part Context

This part belongs to the IDT 74LVCH/ALVC family of low-voltage CMOS logic devices. Similar parts include the IDT74ALVC16244APA, which shares the 16-bit buffer/driver architecture and 3.3V operation. The LVCH variant typically offers lower power consumption compared to the ALVC series while maintaining comparable speed performance for 3.3V applications.

Replacement Considerations

The IDT74ALVC16244APA is a functionally similar 16-bit buffer/driver from the same manufacturer family. Verify pin compatibility and specific drive current differences between the LVCH and ALVC variants before substitution.
