MC74LCX16245DTG

Overview

The MC74LCX16245DTG is a 16-bit bus transceiver manufactured by onsemi, belonging to the LCX logic family. It operates within a supply voltage range of 2.0 V to 3.6 V and features non-inverting data transmission with tri-state outputs. The device provides high drive capability with output currents of 24 mA for both high and low states. It utilizes a 48-pin TSSOP package and supports TTL/CMOS input levels while delivering LVTTL output levels. The component is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports 16-bit bidirectional data transfer between two buses using a single direction control signal.
• Provides robust 24 mA drive strength for reliable signal integrity across system buses.
• Features true 3.3-V operation with tolerance for 5-V tolerant inputs.

Applications

• High-density memory modules requiring wide data bus interfacing
• Consumer electronics utilizing 3.3-V logic systems
• Portable computing devices needing compact surface-mount solutions

Procurement Notes

Verify the specific suffix 'DTG' against official onsemi documentation to confirm the exact tape-and-reel quantity and moisture sensitivity level. Ensure the procurement source provides valid RoHS compliance certificates matching the current manufacturing standards. Cross-reference the date code to confirm production status, as older batches may differ in packaging specifications.

Selection Notes

Select this component when designing systems that require 16-bit wide data paths at 3.3 V logic levels. It is suitable for applications demanding higher drive current than standard CMOS families provide. Consider the 48-pin TSSOP package constraints regarding PCB space and thermal dissipation requirements during the layout phase.

Part Context

This part belongs to the LCX series, which bridges the performance gap between legacy HC/HCT logic and modern LV/LVC families. It offers faster switching speeds and lower power consumption compared to HC devices while maintaining compatibility with 5-V tolerant interfaces. The LCX family is widely used in portable and battery-operated equipment.

Replacement Considerations

Direct pin-to-pin replacements include the SN74LVC16245 from Texas Instruments or the MC74LVX16245 from onsemi. Verify that substitute parts support the same 3.6 V maximum supply voltage and match the required drive current specifications for the target application.
