Overview
The Nexperia 74HCT00BQ,115 is a quad 2-input NAND gate in the 74HCT series. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input levels. The device utilizes DHVQFN14 (SOT762-1) packaging with dimensions of 2.5 x 3 x 0.85 mm. It supports an ambient temperature range from -40 °C to +125 °C. Static characteristics include a maximum low-level output voltage of 0.4 V at 4 mA load and a high-level output voltage of 3.7 V at -4 mA load. Dynamic performance specifies a propagation delay of up to 29 ns at 4.5 V.
Feature Summary
- CMOS technology providing low power dissipation and high noise immunity
- TTL-compatible input logic levels for direct interfacing with TTL systems
- Integrated input clamp diodes allowing current limiting resistors for voltages exceeding VCC
- ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)
Applications
- Digital signal processing logic circuits
- Microcontroller peripheral interface gating
- Memory address decoding networks
Procurement Notes
Verify the specific ordering suffix ',115' corresponds to the DHVQFN14 package configuration. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Ensure supply voltage constraints remain strictly within the 4.5 V to 5.5 V recommended operating conditions to maintain valid logic levels and prevent damage.
Selection Notes
Select this component when TTL-compatible inputs are required alongside CMOS drive capabilities. The DHVQFN14 package offers a compact footprint suitable for space-constrained designs. Verify that the 4 mA output drive current meets the load requirements of the connected circuitry. Consider the thermal dissipation characteristics inherent to the leadless QFN form factor during layout.
Part Context
This part belongs to the 74HCT family, which bridges HC CMOS performance with TTL logic compatibility. The 'BQ' designation identifies the specific DHVQFN14 package variant. The ',115' suffix indicates the standard reel packaging format used by Nexperia for distribution. This series is designed for general-purpose digital applications requiring reliable switching behavior.
Replacement Considerations
Cross-reference with other manufacturers offering 74HCT00 devices in DHVQFN14 packages. Verify pinout compatibility and electrical specifications match the original design requirements before substitution.
