74ACT11008N

Overview

The Texas Instruments 74ACT11008N is a single-function logic gate belonging to the ACT series, featuring four independent 2-input positive AND gates. It utilizes TTL-compatible CMOS input technology and provides push-pull outputs capable of sourcing and sinking up to 24 mA. The device operates within a supply voltage range of 4.5 V to 5.5 V and exhibits a typical propagation delay of 5.8 ns. Designed for through-hole mounting, it is housed in a standard 16-pin PDIP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Features over-voltage tolerant inputs for enhanced signal integrity
• Provides very high-speed operation with propagation delays between 5 and 10 ns
• Delivers strong drive capability with 24 mA output current at both logic levels

Applications

• High-speed digital logic circuits requiring fast switching times
• Data acquisition systems utilizing TTL-compatible interfaces
• General-purpose logic buffering and gating applications

Procurement Notes

Verify the specific package type against design requirements, as the N suffix indicates a PDIP-16 through-hole configuration. Confirm that the 4.5 V to 5.5 V supply voltage range aligns with the target system power rails. Ensure thermal management strategies accommodate the specified -40°C to +85°C operating temperature limits for reliable long-term performance in industrial environments.

Selection Notes

Select this component when TTL compatibility is required alongside CMOS low power consumption characteristics. The 74ACT11008N is suitable for designs needing robust output drive strength compared to standard AC series devices. Consider the PDIP-16 package if through-hole assembly is mandated by the manufacturing process or mechanical constraints of the enclosure.

Part Context

This part belongs to the SN74ACT family of advanced CMOS logic devices manufactured by Texas Instruments. The ACT series bridges the performance gap between older LS-TTL and standard AC logic families, offering faster speeds while maintaining compatible pinouts and electrical characteristics. This specific model implements quad 2-input AND functionality within a widely used industry-standard package format.

Replacement Considerations

Direct functional equivalents include the SN74ACT11008PW (TSSOP-16) for surface-mount applications. Cross-referencing with other manufacturers' 74ACT11008 variants requires verification of pinout compatibility and electrical parameter tolerances to ensure seamless integration without circuit redesign.
