74HCT08BQ,115

Overview

The Nexperia 74HCT08BQ,115 is a quad 2-input AND gate in the 74HCT logic family. It operates on a single supply voltage of 4.5 V to 5.5 V. The device features TTL-compatible input levels and CMOS low power dissipation. It is housed in a 14-terminal DHVQFN package (SOT762-1) with dimensions of 2.5 x 3 x 0.85 mm. The component supports an ambient temperature range from -40 °C to +125 °C and includes input clamp diodes for interfacing.

Feature Summary

• TTL-compatible input levels for direct interface with Transistor-Transistor Logic systems
• CMOS technology providing low power dissipation and high noise immunity
• Robust latch-up performance exceeding 100 mA per JESD 78 Class II Level B
• Integrated input clamp diodes allowing current limiting resistor usage for over-voltage interfacing

Applications

• Digital logic circuits requiring quad 2-input AND functionality
• Mixed 5 V and 3.3 V system interfaces utilizing TTL inputs
• Industrial control applications operating within extended temperature ranges

Selection Notes

Select this component when TTL-level compatibility is required alongside CMOS power efficiency. The DHVQFN package offers space-saving benefits for dense PCB layouts. Ensure the design environment stays within the specified 4.5 V to 5.5 V supply range and -40 °C to +125 °C temperature limits for optimal performance.

Part Context

This part belongs to the 74HCT series, which bridges HC speed with TTL voltage levels. The 'BQ' suffix denotes the DHVQFN14 leadless package variant. It shares functional equivalence with other 74HCT08 types but differs in physical footprint and thermal characteristics compared to SO or TSSOP packages.

Replacement Considerations

Direct pin-to-pin replacements include other manufacturers' 74HCT08 devices in DHVQFN14 packages. Verify voltage levels and propagation delays match application requirements before substitution.
