TC74VHC541FT(EL,M)

Overview

The TC74VHC541FT(EL,M) is an octal bus buffer manufactured by Toshiba Semiconductor and Storage, belonging to the 74VHC logic family. It features eight non-inverting inputs and outputs with three-state capability, housed in a 20-pin TSSOP package. The device operates within a supply voltage range of 2.0 V to 5.5 V, supporting low-voltage digital systems. It provides symmetric drive currents of 8 mA for both high and low output states, ensuring robust signal integrity across various load conditions.

Feature Summary

• Octal configuration providing eight independent non-inverting buffer channels within a single integrated circuit.
• Three-state output architecture allowing multiple drivers to share a common data bus without electrical contention.
• Wide operating voltage compatibility ranging from 2.0 V to 5.5 V, suitable for diverse power supply environments.

Applications

• High-speed data bus buffering in portable electronic devices
• Memory interface signal conditioning in computing hardware
• General-purpose logic level translation between different voltage domains

Procurement Notes

Verify the specific suffix EL,M against official Toshiba documentation to confirm pinout and thermal characteristics. Ensure the component matches the required 20-TSSOP footprint for PCB layout compatibility. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits requiring eight buffered channels with tri-state control. Consider the 2.0 V minimum supply voltage for battery-operated applications. Evaluate the 8 mA drive strength against trace capacitance and fan-out requirements to ensure signal stability at target switching frequencies.

Part Context

This part belongs to the 74VHC series of high-speed CMOS logic devices produced by Toshiba Semiconductor and Storage. The series is characterized by operation similar to standard 74HC logic but optimized for lower power consumption and faster switching speeds. The 541 function code specifically denotes an octal buffer with three-state outputs, widely used in digital system interconnects.

Replacement Considerations

Direct substitutes include the 74VHC541FT(BE) and 74VHC541FT, which share identical logical functions and pin configurations. Verify that alternative packages maintain the same thermal performance and mechanical dimensions for seamless integration into existing designs.
