M74HC541RM13TR

Overview

The M74HC541RM13TR is an octal bus buffer with three-state outputs manufactured by STMicroelectronics. It operates on a silicon gate C2MOS process and provides non-inverting buffering. The device supports a supply voltage range of 2V to 6V. Key electrical parameters include a typical propagation delay of 9ns at 6V, maximum quiescent current of 4µA, and symmetrical output impedance with minimum drive currents of 6mA for both high and low states.

Feature Summary

• Features two independent active-low output enable inputs (G1 and G2) that control the three-state logic function.
• Provides balanced propagation delays between rising and falling edges for signal integrity.
• Includes input protection circuits designed to withstand static discharge and transient excess voltages.

Applications

• High-speed data bus buffering in computing systems
• Clock distribution networks requiring symmetrical timing
• Memory interface circuits utilizing wide operating voltage ranges

Procurement Notes

Verify the specific package type against the ordering code suffix, as the base part number covers multiple packages including SOP and TSSOP. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the manufacturing assembly process.

Selection Notes

Select this component when designing circuits requiring octal buffering with tri-state capability. Ensure the system power supply remains within the 2V to 6V operational limits. Verify that the load capacitance does not exceed specifications to maintain the required propagation delay performance.

Part Context

This component belongs to the 74HC series of advanced high-speed CMOS logic devices. It is functionally compatible with the standard 74LS541 series but offers improved speed and lower power consumption characteristics suitable for modern digital applications.

Replacement Considerations

Direct pin-compatible alternatives include the M74HC541B1R and M74HC541TTR from the same manufacturer family.
