MC74VHCT541ADTR2G

Buffers, Drivers, Receivers, Transceivers Overview

The MC74VHCT541ADTR2G is an octal buffer and line driver manufactured by onsemi, belonging to the VHCT logic family. It features non-inverting inputs with three-state outputs, designed for low-voltage operation between 4.5 V and 5.5 V. The device utilizes CMOS technology and is housed in a 20-TSSOP surface-mount package. Key electrical characteristics include a maximum propagation delay of 8 ns at 3.3 V and static current consumption of 8 µA. Output drive capabilities are specified at -8 mA for high level and 8 mA for low level, supporting interface requirements in digital systems.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight independent non-inverting buffers within a single integrated circuit.
• Three-state output architecture enabling direct connection to bus-oriented systems without external drivers.
• VHCT technology compatibility allowing TTL-level input signals to interface directly with CMOS outputs.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance and halogen-free status as per manufacturer standards. Confirm the TSSOP-20 package dimensions match the design footprint. Ensure the operating temperature range of -40°C to +85°C aligns with system thermal requirements. Cross-reference the datasheet revision date to ensure all electrical parameters are current before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a wide voltage range and TTL-compatible inputs are required for CMOS outputs. The VHCT series offers faster switching speeds compared to standard HCT devices while maintaining similar pinouts. Consider the 20-TSSOP package for space-constrained designs requiring surface-mount assembly. Evaluate the 8 mA output drive strength against load capacitance requirements to ensure signal integrity.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74VHCT541A family of octal buffers. It serves as a bridge between TTL logic levels and CMOS logic levels, facilitating communication in mixed-signal environments. The VHCT series is characterized by its ability to accept standard TTL inputs while providing CMOS-compatible outputs, making it suitable for legacy system upgrades or mixed-voltage interfaces.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

MC74VHCT541ADWR2G is a documented alternative from onsemi using a SOIC-20 package instead of TSSOP. Other potential substitutes include parts from Texas Instruments or Nexperia that match the 74VHCT541 specification, though package and pinout compatibility must be verified independently.
