74HC541DTR2G

Overview

The MC74HC541DTR2G is an octal buffer and line driver manufactured by onsemi, belonging to the 74HC logic family. It features eight non-inverting channels with three-state outputs, enabling efficient bus-oriented communication. The device operates within a supply voltage range of 2.0 V to 6.0 V and utilizes advanced silicon gate CMOS technology for high noise immunity and low power consumption. Packaged in a 20-pin TSSOP, it supports surface-mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent non-inverting signal paths for parallel data transmission.
• Three-state output capability allowing multiple drivers to share a common bus without electrical conflict.
• Dual output enable inputs utilizing AND logic to control data flow or isolate outputs into a high-impedance state.

Applications

• Bus-oriented systems requiring signal buffering and isolation.
• Memory and firmware storage devices interfacing with microprocessors.
• Clock distribution circuits for synchronous digital systems.

Procurement Notes

Verify the specific suffix DTR2G corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 74HC logic level compatibility aligns with the target system's voltage thresholds. Ensure the TSSOP-20 package dimensions match the designated PCB footprint and solder mask specifications to prevent mounting errors during production.

Selection Notes

Select this component when designing systems that require high-density octal buffering with low static power dissipation. The 74HC series offers speed comparable to Low-power Schottky TTL while maintaining standard CMOS advantages. Consider the dual enable inputs for flexible control schemes and verify that the 2V to 6V operating range covers all logic levels present in the application environment.

Part Context

This part belongs to the widely adopted 74HC541 family of octal buffers. It serves as a fundamental building block for digital logic interfaces, providing signal integrity and drive strength. The device is distinct from inverters like the 74HC540 due to its non-inverting nature, making it suitable for direct data path applications where polarity preservation is critical.

Replacement Considerations

Cross-reference with other manufacturers' 74HC541 equivalents such as NXP or Texas Instruments variants. Verify pinout compatibility and electrical parameter alignment before substitution. Note that suffixes may indicate different packaging options rather than functional changes.
