74LVCH16543APAG

Overview

The 74LVCH16543APAG is a 16-bit bus transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.7V to 3.6V and features non-inverting logic with three-state outputs. The device integrates two independent 8-bit elements, providing bidirectional data transfer capabilities for low-voltage applications.

Feature Summary

• Supports bidirectional data transmission across two independent channels
• Provides three-state output capability for efficient bus management
• Compatible with standard LVTTL input levels

Applications

• Memory mapping control circuits
• Clock drivers and buffer applications
• Bidirectional bus architecture implementations

Procurement Notes

Verify the specific package marking and manufacturer date code upon receipt to ensure authenticity. Confirm that the component matches the exact suffix APAG for pin compatibility. Check for physical damage to leads before soldering. Ensure storage conditions comply with moisture sensitivity level requirements to prevent internal degradation during assembly processes.

Selection Notes

Select this component when designing systems requiring 16-bit wide data paths at 3.3V logic levels. It serves as a direct replacement for similar LVCH series devices from other manufacturers. Consider its propagation delay characteristics relative to system timing constraints. Evaluate power consumption requirements against alternative low-power logic families for optimal efficiency.

Part Context

This part belongs to the 74LVCH family of CMOS logic devices designed for low-voltage operation. It is functionally equivalent to industry-standard bus transceivers but optimized for 3.3V environments. The device supports high-speed data transfer while maintaining low power dissipation suitable for portable and battery-operated electronic equipment designs.

Replacement Considerations

Public confirmed substitute part numbers include SN74LVCH16543ADGGR and SN74LVCH16543ADL from Texas Instruments.
