SN74ACT08DRG4

Overview

The SN74ACT08DRG4 is a quad 2-input AND gate from the Texas Instruments 74ACT logic family, housed in a 14-pin SOIC package. It operates on a single supply voltage ranging from 4.5 V to 5.5 V. The device provides symmetric output drive capabilities with low-level and high-level output currents of 24 mA each. Propagation delay is specified at 9 ns when driven at 5 V with a 50 pF load. It functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Contains four independent 2-input AND logic gates within a single integrated circuit
• Features robust 24 mA output drive strength for both high and low states
• Operates exclusively at a standard 5 V logic supply level

Applications

• Digital signal gating and data path selection
• Logic control circuits requiring 5 V interface compatibility
• General-purpose Boolean logic operations in embedded systems

Procurement Notes

Verify that the specific part number suffix matches the required tape-and-reel packaging configuration. Confirm RoHS compliance status as indicated by the manufacturer's documentation. Ensure the operating environment remains within the specified -40°C to +85°C temperature limits. Validate that the system power supply strictly adheres to the 4.5 V to 5.5 V range to prevent functional failure or damage.

Selection Notes

Select this component when a 5 V logic interface is mandatory and higher speed than standard 74LS series is required. The 24 mA drive capability supports moderate capacitive loads without external buffering. Consider alternative packages if surface area constraints differ from the SOIC-14 footprint. This device is suitable for designs needing multiple AND functions in a compact form factor.

Part Context

This component belongs to the 74ACT series, which bridges the performance gap between older TTL technologies and modern CMOS families. It offers faster switching speeds than LS variants while maintaining compatible input/output voltage levels for legacy 5 V systems. The ACT series is widely used in mixed-voltage environments where 5 V signaling is still prevalent.

Replacement Considerations

The SN74ACT08DRG3 is a verified substitute offering identical logical functionality and pinout compatibility. Both parts share the same 74ACT logic family characteristics and electrical specifications.
