• High drive current capability for large bus capacitance loads
• Low static power consumption characteristic of CMOS technology
• Input protection against electrostatic discharge via diodes

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• Bidirectional data bus transceivers
• TTL-to-CMOS level translation interfaces

Procurement Notes

Verify the specific suffix 'DWR2G' to confirm the tape-and-reel packaging format and RoHS compliance status. Ensure the ordering quantity aligns with the manufacturer's standard reel size requirements. Cross-reference the datasheet revision date to confirm compatibility with your design specifications before finalizing procurement orders.

Selection Notes

Select this component when non-inverting signal buffering is required for 8-bit wide buses. It is appropriate for systems operating between 2V and 6V where low quiescent current is critical. Compare against HC family alternatives if higher speed or different voltage thresholds are needed. Verify that the 20-SOIC footprint matches the PCB layout constraints.

Part Context

This part is an octal buffer within the widely used 74HC logic family. It serves as a fundamental building block for digital systems requiring signal isolation and drive enhancement. The device complements other 74-series components like the inverting MC74HC540, providing versatile options for bus architecture design in consumer and industrial electronics.

FAQ

How is the three-state function controlled?

The three-state outputs are controlled by two gate inputs, GI and G2. When either input is high, all eight outputs enter a high-impedance state.

What is the typical propagation delay?

The typical propagation delay is approximately 12ns at a 5V supply voltage, allowing for high-speed operation comparable to low-power Schottky TTL devices.
