74AC02MTR

Overview

The STMicroelectronics 74AC02MTR is a quad 2-input NOR gate in a 14-pin SOIC package. It operates on a supply voltage of 2V to 6V, featuring a typical propagation delay of 4.2ns at 5V and maximum quiescent current of 2μA. The device provides symmetrical output drive with minimum currents of 24mA for both high and low states. It includes protection circuits offering 2kV ESD immunity and improved latch-up resistance.

Feature Summary

• Advanced CMOS fabrication using sub-micron silicon gate and double-layer metal wiring technology
• Internal three-stage circuit architecture with buffer outputs for stable operation
• Integrated protection circuits against static discharge and transient excess voltage

Applications

• High-speed digital logic processing
• Transmission line driving applications
• General-purpose NOR logic operations

Procurement Notes

Verify the specific ordering code matches the required package type, as the 74AC02MTR designation corresponds to the SOP-14 variant. Confirm that the tape and reel packaging aligns with automated assembly requirements. Ensure the component version meets the necessary operating temperature range specifications for the intended deployment environment.

Selection Notes

Select this component when a quad NOR gate configuration is required within a compact surface-mount footprint. The AC series offers superior speed compared to standard logic families while maintaining low power dissipation. Verify compatibility with existing system voltage levels, specifically ensuring the 2V to 6V operating range suits the design constraints.
