SN74HCT08DR

Inverter Gates Overview

The SN74HCT08DR is a quadruple 2-input positive-AND gate manufactured by Texas Instruments in the HCT logic series. It operates within a supply voltage range of 4.5V to 5.5V and features TTL-voltage compatible inputs with low input current of 1µA maximum. The device provides ±4mA output drive at 5V and can drive up to 10 LSTTL loads. Typical propagation delay is 13ns, with a maximum of 27ns at 5.5V. It is housed in a 14-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Inverter Gates Procurement Notes

Verify the specific orderable part number against the Package Option Addendum to confirm status, material type, lead finish, and moisture sensitivity level. Ensure the selected variant matches the required packaging quantity and carrier type for your assembly process. Cross-reference thermal metrics and absolute maximum ratings during design validation to prevent overstress conditions.

Inverter Gates Selection Notes

Select this component when TTL-compatible input levels are required alongside CMOS performance characteristics. The HCT series ensures compatibility with standard 5V TTL logic families while offering lower power consumption than older LS variants. Consider the SOIC package dimensions and thermal resistance values for PCB layout and heat dissipation requirements in dense designs.

Inverter Gates Part Context

This device belongs to the SN74HCT08 family of quadruple 2-input positive-AND gates. It is part of Texas Instruments' broader portfolio of digital logic integrated circuits designed for general-purpose applications. The HCT series bridges the gap between high-speed CMOS technology and traditional TTL logic standards, providing versatile solutions for mixed-logic system designs.

Inverter Gates Replacement Considerations

SN74HCT08DRE4 and SN74HCT08DRG4 are confirmed active production replacements for the SN74HCT08DR in the same SOIC package.
