74HCT08DB,118

Overview

The Nexperia 74HCT08DB,118 is a quad 2-input AND gate in the 74HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL-compatible input levels and includes clamp diodes on inputs for overvoltage interfacing. It is housed in a SO14 plastic small outline package (SOT108-1) with 14 leads. Static characteristics specify low power dissipation and high noise immunity, while dynamic performance indicates propagation delays up to 36 ns at 4.5 V.

Feature Summary

• Quad 2-input AND logic function
• TTL-compatible input voltage levels
• Wide operating temperature range
• ESD protection exceeding specified JEDEC standards

Applications

• Digital signal processing logic gates
• Microcontroller peripheral interface circuits
• General-purpose logic control systems

Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and ensure the component meets required automotive or industrial qualification standards if applicable to the design. Cross-reference the manufacturer part number with distributor catalogs to validate availability and authenticity before procurement.

Selection Notes

Select this component when TTL-level compatibility is required alongside CMOS output drive capabilities. The 74HCT series ensures direct interfacing with older TTL logic families without level shifting. Consider the SO14 package dimensions for PCB layout constraints and verify that the maximum propagation delay meets the timing requirements of the target digital circuit application.

Part Context

This component belongs to the 74HCT08 family of quad 2-input AND gates manufactured by Nexperia. It is part of the broader 74HC/HCT logic portfolio designed for general-purpose digital applications. The 'DB' designation specifically identifies the SO14 surface-mount package variant within the product line.

Replacement Considerations

Compatible substitutes include other manufacturers' 74HCT08 devices in SOIC-14 packages. Verify pinout compatibility and electrical parameters such as propagation delay and output current drive before substitution.
