74AC11008D

Overview

The Texas Instruments SN74AC11008D is a single-function logic gate IC belonging to the 74AC series. It contains four independent 2-input AND gates housed in a 14-pin SOIC surface-mount package. The device operates within a supply voltage range of 2V to 6V, supporting TTL-compatible CMOS inputs and push-pull outputs. Key electrical characteristics include a maximum low-level output current of 24mA and a high-level output current of -24mA. Propagation delay is specified at 7.5ns when operating at 5V with a 50pF load. The component is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Contains four independent 2-input positive-AND logic gates
• Features TTL-compatible CMOS input structure
• Provides push-pull output configuration for robust drive capability

Applications

• Digital signal processing logic circuits
• Microprocessor-based system control interfaces
• General-purpose logic gating in consumer electronics

Procurement Notes

Verify the specific suffix 'D' corresponds to the 14-SOIC package variant during procurement. Confirm that the required supply voltage range aligns with the 2V to 6V specification. Ensure the design accommodates the 7.5ns propagation delay at the target operating frequency. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when four independent AND functions are required in a compact surface-mount form factor. The 74AC series offers higher speed than standard 74LS equivalents while maintaining compatibility with 5V logic levels. Consider the 14-SOIC package for PCB space constraints where through-hole options are unsuitable. Verify that the 24mA output drive current meets the fan-out requirements of connected loads.

Part Context

This part belongs to the SN74AC11008 family of quadruple 2-input AND gates manufactured by Texas Instruments. The AC series represents advanced CMOS technology designed for high-speed applications. Similar variants exist in different packages such as TSSOP or DIP, and other logic families like ACT offer comparable performance with slight parameter variations. The D suffix specifically denotes the SOIC-14 package style.

Replacement Considerations

Compatible substitutes include the SN74ACT11008D for similar performance with ACT series characteristics. Other manufacturers may offer pin-compatible alternatives, but verify voltage ranges and propagation delays carefully. Ensure any replacement maintains the 14-SOIC footprint and supports the required 2V to 6V operating range.
