SN74ACT08DE4

Overview

The SN74ACT08DE4 is a quad 2-input positive-AND gate manufactured by Texas Instruments. It belongs to the ACT logic series and utilizes CMOS technology. The device operates within a supply voltage range of 4.5 V to 5.5 V. It features a low-level output current of 24 mA and a high-level output current of -24 mA. The propagation delay is specified at 10 ns. The component is housed in a PDIP-14 package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Contains four independent 2-input AND gates for complex logic implementation
• Provides high drive capability with 24 mA output current
• Ensures signal integrity through fast 10 ns propagation delay
• Compatible with standard 5 V logic systems

Applications

• Digital data processing circuits
• Clock gating applications
• Memory address decoding
• Control logic interfaces

Procurement Notes

Verify the DE4 suffix indicates lead-free construction and RoHS compliance when sourcing. Confirm the PDIP-14 package type matches your PCB footprint requirements. Ensure the 4.5 V to 5.5 V supply voltage aligns with your system design. Check for automotive or extended temperature variants if operating conditions exceed standard ranges. Validate pinout compatibility during integration planning.

Selection Notes

Select this component for designs requiring moderate speed and high drive strength in standard 5 V environments. The ACT series offers improved performance over older LS families while maintaining pin compatibility. Consider the PDIP-14 package for through-hole mounting needs. Evaluate power consumption against HC or HCT alternatives if lower static power is critical. Verify thermal management capabilities for the specified temperature range.

Part Context

This part is part of the SN74ACT family, which bridges the performance gap between AC and ALST logic families. It provides faster switching speeds than standard TTL while offering CMOS input characteristics. The quad configuration allows multiple logic functions on a single chip, reducing board space. It serves as a direct replacement for many legacy 74LS08 designs in modern systems.

Replacement Considerations

SN74ACT08N is a verified equivalent part number from Texas Instruments.
