74HCT03DB,112

Overview

The NXP USA Inc. 74HCT03DB,112 is a quad 2-input NAND gate with open-drain outputs from the 74HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features TTL-level inputs and includes clamp diodes for interfacing with voltages exceeding VCC. It complies with JEDEC standard no. 7A and offers ESD protection exceeding 2000 V (HBM) and 200 V (MM). The component is housed in an SSOP-14 package.

Feature Summary

• Quad 2-input NAND gates with open-drain output configuration
• TTL-compatible input levels for direct interface with TTL systems
• Input clamp diodes enable current limiting resistor usage for high-voltage interfacing
• High electrostatic discharge protection capability

Applications

• Digital logic signal processing
• Interface circuits requiring open-drain pull-up configurations
• General-purpose switching applications

Procurement Notes

Verify the specific ordering suffix '112' against official Nexperia/NXP documentation to confirm the SSOP-14 package variant. Ensure compatibility with the required operating temperature range of -40 °C to +125 °C. Confirm that the open-drain output topology aligns with the system design requirements, as this differs from push-pull outputs.

Selection Notes

Select this component when TTL-level input compatibility is required alongside open-drain output functionality. The 74HCT series ensures compatibility with standard 5V logic systems while providing robust ESD protection. Verify that the external circuitry accommodates the open-drain nature by including appropriate pull-up resistors on the output lines.

Part Context

This part belongs to the 74HCT03 family of quad 2-input NAND gates. The 'DB' designation specifically identifies the SSOP-14 plastic shrink small outline package variant. It is distinct from the SO14 and TSSOP-14 versions available within the same logical family.
