74AC04MTR

Overview

The STMicroelectronics 74AC04MTR is a hex inverter integrated circuit fabricated using advanced sub-micron silicon gate and double-layer metal wiring C2MOS technology. It operates within a supply voltage range of 2V to 6V, providing high-speed performance with a typical propagation delay of 4ns at 5V. The device features low power dissipation with a maximum quiescent current of 2µA and symmetrical output impedance capable of sourcing and sinking 24mA. It includes protection circuits against static discharge, offering 2kV ESD immunity.

Feature Summary

• Advanced high-speed CMOS architecture utilizing sub-micron silicon gate and double-layer metal wiring for enhanced performance.
• High noise immunity with balanced propagation delays and capability for 50Ω transmission line driving.
• Robust input and output protection circuits designed to withstand 2kV electrostatic discharge events.

Applications

• General-purpose logic inversion in digital circuits
• Signal buffering and waveform shaping
• Clock signal generation and conditioning

Procurement Notes

Verify the specific package type (SO-14) and tape-and-reel configuration when ordering, as the MTR suffix indicates reel packaging. Confirm that the component meets the required operating temperature range of -55°C to 125°C for your application environment. Ensure compatibility with existing PCB footprints and verify that the 2V to 6V supply voltage aligns with system power rails before procurement.

Selection Notes

Select this component when high-speed switching and low power consumption are critical requirements. The 74AC series offers superior speed compared to standard 74LS logic while maintaining lower power than 74HC families. Consider the 24mA drive strength for direct interfacing with moderate loads. Verify that the 2V minimum supply voltage supports your lowest operating condition.

Part Context

This part belongs to the 74AC family of advanced CMOS logic devices produced by STMicroelectronics. The base part number 74AC04 designates a hex inverter function. The MTR suffix specifically denotes the SO-14 surface-mount package supplied in a tape-and-reel format, distinguishing it from tube-packaged variants like the 74AC04M.

Replacement Considerations

Compatible substitutes include the 74AC04TTR (TSSOP-14 package) from the same manufacturer. Other manufacturers produce equivalent 74AC04 parts, but verify pinout compatibility and electrical specifications such as propagation delay and output current capabilities before substitution.
