SN74AHCT08D Description

The SN74AHCT08D from Texas Instruments is a high-speed quad 2-input AND gate IC designed for robust digital logic applications. Housed in a 14-pin SOIC package, it operates within a 4.5V to 5.5V supply range, making it ideal for 5V TTL-compatible systems. With a maximum propagation delay of 7.9ns at 5V and 50pF load, it ensures fast signal processing, while its low quiescent current (2µA max) enhances power efficiency. The device features 4 independent AND gates, each accepting 2 inputs with defined logic thresholds (0.8V low, 2V high), ensuring reliable noise immunity.

SN74AHCT08D Features

• High-Speed Performance: 7.9ns propagation delay at 5V enables rapid signal transitions.
• Low Power Consumption: 2µA max quiescent current minimizes energy use in idle states.
• TTL-Compatible Inputs: 2V high-level and 0.8V low-level thresholds ensure seamless interfacing with TTL logic.
• Balanced Output Drive: 8mA output current (sink/source) supports moderate fan-out requirements.
• Robust Construction: ROHS3 compliant, REACH unaffected, and MSL 1 (unlimited) rated for reliability in harsh environments.
• Surface-Mount Design: 14-SOIC package optimizes board space in compact layouts.
