74LCX245WM

Overview

The onsemi 74LCX245WM is an octal bus transceiver featuring low-voltage CMOS technology. It operates within a supply voltage range of 2 V to 3.6 V and utilizes a 20-SOIC surface-mount package. The device provides non-inverting, three-state outputs with a propagation delay of 8 ns. It supports LVTTL and TTL input levels while delivering LVCMOS output levels. Each output can source or sink up to 24 mA. The component functions as a single circuit with eight channels and maintains a maximum power supply current of 10 uA across an operating temperature range of -40°C to +85°C.

Feature Summary

• Bidirectional data transfer capability between two buses using a common direction control signal
• Low-voltage operation compatible with systems requiring 2 V to 3.6 V power supplies
• High drive strength outputs capable of sourcing and sinking 24 mA for robust signal integrity

Applications

• Memory bus architectures requiring bidirectional data flow
• Clock distribution networks in low-voltage digital systems
• Data acquisition systems utilizing mixed logic families

Procurement Notes

Verify the specific manufacturing date code and lot traceability upon order confirmation. Confirm RoHS compliance status directly with the supplier, as environmental declarations may vary by production batch. Ensure the procurement channel is authorized to guarantee authenticity. Check for any obsolescence notices or last-time buy notifications from onsemi before finalizing purchase commitments.

Selection Notes

Select this component when designing circuits that require bidirectional data transfer between different voltage domains. The 74LCX series offers lower power consumption compared to older HC or HCT families. Verify that the system's I/O requirements align with the 24 mA drive capability. Ensure the 20-SOIC footprint matches the PCB layout constraints. Consider the 8 ns propagation delay against the system's timing budget.

Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices manufactured by onsemi. The LCX series is designed to replace higher voltage logic families in modern portable and battery-operated applications. It shares functional compatibility with other standard octal bus transceivers but distinguishes itself through optimized low-voltage performance and reduced power dissipation characteristics typical of the LCX architecture.

Replacement Considerations

MC74LCX245DWG and MC74LCX245DWR2G are confirmed similar alternatives from onsemi.
