SN74HCT08DRG4

Inverter Gates Overview

The SN74HCT08DRG4 is a quadruple 2-input positive-AND gate in the HCT logic series, housed in a 14-pin SOIC package. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. The device provides ±4mA output drive at 5V and features TTL-voltage compatible inputs with low input current of 1µA max. Typical propagation delay is 13ns, with maximum values reaching 27ns at 5.5V. Supply current is limited to 20µA max.

Inverter Gates Feature Summary

• TTL-voltage compatible inputs allow direct interfacing with standard TTL logic systems.
• Outputs can drive up to 10 LSTTL loads, ensuring robust signal transmission.
• Low power consumption design minimizes overall system energy usage.

Inverter Gates Applications

• Boolean logic implementation for digital circuits
• Signal gating and data routing
• Interface between TTL and CMOS logic families

Inverter Gates Procurement Notes

Verify the part number suffix G4 indicates lead-free and RoHS compliance status as per Texas Instruments specifications. Confirm the SOIC (D) package type matches the required footprint. Ensure the operating temperature range meets the environmental requirements of the target application before finalizing procurement.

Inverter Gates Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS performance characteristics. The HCT series bridges the gap between older TTL standards and modern low-power designs. Consider the 14-pin SOIC package for surface-mount assembly needs. Evaluate the 4.5V to 5.5V supply constraint against the system power rails.

Inverter Gates Part Context

This device belongs to the SN74HCT08 family of quadruple 2-input AND gates manufactured by Texas Instruments. It is part of the broader 74xx logic family, specifically designed for high-speed CMOS technology with TTL compatibility.
