MC74AC541MG

Overview

The MC74AC541MG is an octal buffer and line driver from the AC logic series, manufactured by onsemi. It features eight non-inverting channels with three-state outputs housed in a TSSOP-20 package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a maximum propagation delay of 8 ns at 3.3 V and 6 ns at 5 V. Output drive capability is specified at 24 mA for both sourcing and sinking currents. Static current consumption is typically 4 uA, while operating power supply current reaches 40 uA. The component supports an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Provides eight non-inverting signal paths with independent dual output enable controls for bus isolation.
• Features three-state outputs that transition to high impedance when enabled signals are inactive.
• Utilizes CMOS technology to achieve low static power dissipation alongside high-speed operation.

Applications

• Memory address and data bus driving
• Clock signal distribution buffers
• Microprocessor I/O port expansion

Procurement Notes

Verify the specific suffix MG corresponds to the TSSOP-20 surface-mount package configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the ordering part number matches the required voltage and speed specifications for the target application design.

Selection Notes

Select this component for applications requiring octal buffering with low power consumption. The AC series offers faster switching speeds compared to standard HC logic. Verify that the 2 V to 6 V operating range aligns with the system power rails. Consider the TSSOP-20 package constraints for PCB layout density and thermal management requirements.

Part Context

This device belongs to the MC74AC541 family of octal bus drivers. It serves as a non-inverting counterpart to the MC74AC540. The family is designed for high-density digital systems requiring reliable signal transmission across multiple lines simultaneously.

FAQ

How many output enable inputs does the MC74AC541MG have?

The device features two independent output enable inputs (OE1 and OE2) that control the state of all eight outputs simultaneously.

What is the polarity of the outputs?

The MC74AC541MG provides non-inverting outputs, meaning the output logic state follows the input logic state when enabled.
