MC74HCT541ADTR2G

Overview

The MC74HCT541ADTR2G is an octal buffer and line driver manufactured by onsemi, belonging to the 74HCT logic series. It features non-inverting functionality with three-state outputs, enabling effective bus-oriented connections. The device operates within a supply voltage range of 4.5V to 5.5V and utilizes silicon gate CMOS technology for low power consumption. It is housed in a 20-TSSOP surface-mount package and supports propagation delays of approximately 30ns at typical conditions.

Feature Summary

• Octal configuration providing eight independent non-inverting buffers or line drivers within a single integrated circuit.
• Three-state output capability allows direct connection to bus lines without additional interface hardware.
• CMOS construction ensures high noise immunity and low static power dissipation compared to earlier logic families.
• TTL-compatible input thresholds facilitate seamless interfacing between HCT devices and standard TTL logic sources.

Applications

• Bus-oriented memory and address data word selection systems
• Clock buffering and distribution networks
• Pattern generation and digital signal routing

Procurement Notes

Verify the specific suffix ADTR2G to confirm the TSSOP-20 package and tape-and-reel packaging format. Ensure compatibility with the required operating temperature range of -55°C to +125°C for industrial applications. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Selection Notes

Select this component when an octal buffer with three-state control is required for 5V logic systems. It serves as a suitable alternative to legacy 74HCT541 variants, offering improved performance characteristics while maintaining pin-out compatibility. Consider the TSSOP package constraints regarding thermal management and board space availability during design integration.

Part Context

This part belongs to the widely adopted 74HCT family of logic integrated circuits, designed to bridge the gap between older TTL standards and modern CMOS technologies. The 541 variant specifically addresses the need for high-drive capacity and bidirectional data flow control in complex digital architectures.

Replacement Considerations

Compatible substitutes include MC74HCT541ADWR2G (SOIC-20 package) and MC74HCT541ADTR2G (identical specification). Verify package dimensions and moisture sensitivity levels before substituting to ensure mechanical fit and assembly process integrity.
