M74LCX16245DTR2G

Overview

The M74LCX16245DTR2G is an octal bus transceiver from the MC74LCX series, manufactured by onsemi. It features dual power supply rails to facilitate voltage translation between different logic domains. The device operates with a VCCB supply range of 2.7V to 3.6V and supports A/VCCA input levels ranging from 1.65V to 3.6V. It provides three-state outputs and includes an output enable pin. The component is housed in a 48-pin TSSOP package and is designed for surface-mount applications.

Feature Summary

• Supports bidirectional data transmission between two independent buses
• Enables voltage translation between 1.65V to 3.6V and 2.7V to 3.6V domains
• Features three-state outputs controlled by an active-low output enable signal

Applications

• Mobile phone applications requiring low-voltage interface translation
• Portable equipment utilizing multiple voltage logic levels
• Consumer electronics systems needing compact bus interconnect solutions

Procurement Notes

Verify the specific suffix 'DTR2G' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS directives and check for any recent product change notices regarding manufacturing location or material composition before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require interfacing between 1.65V logic sources and 3.3V loads. The LCX series offers lower power consumption compared to older LVX technologies. Confirm that the required propagation delay and drive current meet the system timing constraints for the target application frequency.

Part Context

This part belongs to the MC74LCX family of CMOS logic devices, which are optimized for low-voltage operation. The LCX series is widely used in portable electronics due to its reduced power dissipation and compatibility with various I/O standards. It serves as a standard solution for level shifting in mixed-voltage digital circuits.

Replacement Considerations

Direct substitutes include other MC74LCX16245 variants with compatible packaging. Verify pinout compatibility and electrical characteristics such as propagation delay and output current when considering alternative manufacturers or updated revisions within the same logic family.
