74AHCT1G08DBVTE4

Overview

The SN74AHCT1G08DBVTE4 is a single 2-input positive AND gate from Texas Instruments, belonging to the AHC (Advanced High-Speed CMOS) family with HCT-compatible inputs. It operates within a supply voltage range of 2.0 V to 5.5 V and features low static power consumption. The device utilizes a 5-pin SOT-23 surface-mount package. Key electrical characteristics include an output drive capability of 8 mA and a typical propagation delay of 5.9 ns at 5.0 V. It supports industrial temperature ranges and complies with RoHS standards.

Feature Summary

• HCT-compatible input logic levels ensure seamless interoperability with standard TTL-driven systems while maintaining advanced CMOS performance benefits.
• High-speed switching capabilities provide fast signal processing suitable for demanding digital applications requiring minimal latency.
• Low power dissipation design reduces overall system energy consumption during operation compared to legacy logic families.

Applications

• Portable battery-powered equipment requiring efficient power management
• Consumer electronics utilizing high-density logic circuits
• Computing products needing reliable data processing gates

Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and environmental compliance when sourcing. Confirm the package type matches the PCB footprint requirements. Ensure the operating voltage aligns with the 2.0 V to 5.5 V specification. Check for RoHS and REACH compliance documentation. Validate the manufacturer source to guarantee authenticity.

Selection Notes

Select this component when interfacing between 5 V logic domains and lower voltage CMOS circuits. It serves as a direct replacement for older 74HC or 74HCT equivalents in space-constrained designs. Consider the SOT-23 package for compact board layouts. Evaluate the propagation delay against system timing constraints. Verify input compatibility with existing driver outputs.

Part Context

This part belongs to the SN74AHC1G08 series of single-function gates. It shares the same logical function as the SN74AHC1G08 but differs in input threshold characteristics to match HCT standards. The DBVT variant denotes the specific SOT-23-5 packaging configuration used for surface mount assembly.

Replacement Considerations

SN74AHC1G08DBVR offers identical functionality without HCT input thresholds. SN74LVC1G08DBVTE4 provides higher current drive but different input voltage requirements. SN74AHCT1G08DBVR is the non-green equivalent version.
