74HC08DB,118

Overview

The Nexperia 74HC08DB,118 is a quad 2-input AND gate in the HC logic family. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device utilizes a SO14 plastic small outline package (SOT108-1) with a body width of 3.9 mm. Static characteristics include high-level output voltages up to 5.81 V at 6.0 V supply and low-level output currents of 5.2 mA. Dynamic performance features propagation delays ranging from 7 ns to 23 ns depending on voltage conditions.

Feature Summary

• CMOS technology providing low power dissipation and high noise immunity
• Inputs equipped with clamp diodes for interfacing with voltages exceeding VCC
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
• ESD protection compliant with ANSI/ESDA/JEDEC JS-001 class 2 and JS-002 class C3

Applications

• Digital signal processing logic circuits
• Microcontroller input/output expansion
• General-purpose logic control systems

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the DB designation corresponds to the SO14 form factor. Confirm that the component meets the necessary environmental specifications for the intended operating temperature range. Ensure compliance with RoHS directives and JEDEC standards relevant to the application environment before finalizing procurement orders.

Selection Notes

Select this component when a quad 2-input AND function is required within standard CMOS logic families. The wide supply voltage capability allows compatibility with various digital system architectures. Consider the thermal derating requirements for total power dissipation if operating near maximum temperature limits or utilizing multiple gates simultaneously under heavy load conditions.

Part Context

This part belongs to the Nexperia 74HC series, which adheres to JEDEC JESD7A standards for operation across 2.0 V to 6.0 V. The product data sheet revision history indicates that previous SSOP variants were removed in version 8, establishing the current SO14 and TSSOP options as the primary surface-mount packages for this logic family.

Replacement Considerations

Direct substitutes include other manufacturers' 74HC08 devices in SOIC-14 packages. Verify pinout compatibility and electrical parameters such as propagation delay and output drive strength against the original datasheet specifications to ensure functional equivalence.
