74ACT00TTR

Overview

The STMicroelectronics 74ACT00TTR is a quad 2-input NAND gate IC in a 14-TSSOP package. It operates on a supply voltage of 4.5V to 5.5V with a maximum quiescent current of 2µA. The device features symmetrical output drive capabilities of 24mA for both high and low states, ensuring balanced propagation delays. It provides high noise immunity and stable outputs through an internal three-stage circuit design.

Feature Summary

• Advanced high-speed CMOS fabrication using sub-micron silicon gate technology
• Direct interface compatibility with TTL, NMOS, and CMOS systems
• Enhanced latch-up immunity and protection against static discharge

Applications

• High-speed digital logic circuits
• Transmission line driving applications
• General-purpose logic processing

Procurement Notes

Verify the component status as obsolete or end-of-life before procurement planning. Confirm that replacement components maintain pin and function compatibility with the original 74ACT series specifications. Ensure the selected substitute supports the required operating temperature range and voltage parameters.

Selection Notes

Select this component for designs requiring fast switching speeds and low power dissipation within standard 5V logic environments. Verify that the application environment does not exceed the absolute maximum ratings for input and output voltages. Ensure proper ESD handling procedures are followed during assembly due to the CMOS construction.

Part Context

This part belongs to the 74ACT family of advanced high-speed CMOS logic devices. It serves as a direct replacement for older 74LS series parts while offering significantly faster performance and lower power consumption. The TSSOP package provides a compact surface-mount solution for modern electronic assemblies.

Replacement Considerations

SN74ACT00PWR by Texas Instruments is a confirmed direct substitute.
