74LCX16245G

Overview

The onsemi 74LCX16245G is a 16-bit bus transceiver featuring 3-state outputs and a direction control pin. It operates within a supply voltage range of 1.65V to 3.6V, ensuring compatibility with low-voltage CMOS logic families. The device supports mixed 3.3V/5V environments through its high-impedance state when VCC is zero. It utilizes a standard pin-out architecture for efficient data transfer between buses.

Feature Summary

• Supports bidirectional data transmission across two 8-bit buses
• Provides high-impedance isolation when power is removed
• Enables direct interface with TTL-compatible logic levels

Applications

• Mixed voltage system interconnects
• Memory bus buffering
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'G' against the manufacturer's current datasheet to confirm lead-free status and RoHS compliance. Ensure the package type matches the required PCB footprint. Confirm that the operating temperature range meets the specific environmental requirements of the target application before finalizing procurement.

Selection Notes

Select this component for applications requiring wide voltage flexibility between 1.65V and 3.6V. It is suitable for designs needing 3-state output control to prevent bus contention. Consider the propagation delay specifications if signal integrity at high speeds is critical. Verify input tolerance levels if interfacing directly with 5V logic sources.

Part Context

This part belongs to the LCX family of low-voltage CMOS logic devices. It serves as a general-purpose bus transceiver within the broader category of digital logic integrated circuits. The device is designed to replace older technology nodes while maintaining backward compatibility with existing system architectures.

Replacement Considerations

Check for equivalent parts from other manufacturers such as NXP or Texas Instruments. Verify pin compatibility and electrical characteristics before substitution. Ensure the replacement part meets the same voltage and speed requirements.
