SN74HCT08DRE4

Inverter Gates Overview

The SN74HCT08DRE4 is a quadruple 2-input positive-AND gate manufactured by Texas Instruments. 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 features TTL-compatible inputs with low input current (1µA max) and provides ±4mA output drive at 5V. Typical propagation delay is 13ns, with maximum values up to 30ns depending on voltage. It consumes 20µA max ICC and drives up to 10 LSTTL loads. The component is housed in a 14-pin SOIC package.

Inverter Gates Feature Summary

• Contains four independent 2-input AND gates performing Boolean function Y = A • B
• TTL-voltage compatible inputs ensure compatibility with standard logic families
• Low power consumption with maximum supply current of 20µA
• Capable of driving up to 10 LSTTL loads

Inverter Gates Applications

• Digital logic circuits requiring multiple AND operations
• Systems interfacing TTL outputs with CMOS inputs
• General-purpose boolean logic implementation

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'E4' indicates lead-free composition and RoHS compliance as per TI standards. Confirm the package type matches the required PCB footprint for the SOIC-14 configuration. Ensure the operating environment stays within the specified -40°C to 85°C temperature range. Check for any recent product discontinuation notices or lifecycle status changes directly from the manufacturer before finalizing procurement plans.

Inverter Gates Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS performance characteristics. It is suitable for designs needing multiple independent AND gates in a single package. Consider the 13ns typical propagation delay for timing-critical applications. Verify that the 4.5V to 5.5V supply voltage aligns with the system's power rails. Evaluate thermal resistance metrics if high ambient temperatures are expected.

Inverter Gates Part Context

This part belongs to the SN74HCT08 family of quadruple 2-input positive-AND gates. It shares functional similarities with other HCT series devices but offers specific electrical characteristics tailored for TTL-to-CMOS interfacing. The DRE4 designation specifies the SOIC package, tape-and-reel packaging, and environmental compliance. It serves as a fundamental building block for digital logic design within the broader Texas Instruments logic portfolio.

Inverter Gates Replacement Considerations

SN74HCT08DR is a direct alternative with identical functionality and specifications, differing primarily in manufacturing lot or minor process variations without changing the core electrical parameters or pinout configuration.
