TC74HC541APF

Overview

The TC74HC541APF is an eight-channel buffer and line driver manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 2.0V to 6.0V and features three-state outputs controlled by dual-input AND gates with low-active inputs. The device utilizes CMOS logic technology, offering high noise immunity and low power consumption. It is housed in a 20-pin DIP package and supports data transmission from input terminals to output terminals when enabled.

Feature Summary

• Eight-channel non-inverting buffer configuration
• Three-state output capability for bus driving
• Dual active-low output enable controls
• CMOS construction for low power operation

Applications

• Memory module address and data buffering
• Clock distribution circuits
• General-purpose digital signal isolation

Procurement Notes

Verify the specific suffix 'PF' corresponds to the 20-pin DIP package variant. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the operating temperature range requirements align with the standard industrial specifications for this logic family.

Selection Notes

Select this component for applications requiring eight-channel buffering with tri-state control. Compare against other 74HC series variants if different packaging options like SOP or TSSOP are preferred. Verify that the 2.0V to 6.0V supply voltage range meets the system's power constraints.

Part Context

This part belongs to the 74HC logic family, known for high-speed CMOS operation compatible with TTL standards. The 541 designation specifically indicates an octal buffer with three-state outputs. Toshiba offers various package options including DIP, SOP, and TSSOP for this functional architecture.

Replacement Considerations

Compatible substitutes include the 74HC541D (SOIC package) and TC74HC541AF (SOP package). Cross-reference pinouts and electrical characteristics to ensure compatibility with existing PCB layouts and circuit designs.
