74HCT03PW,112

Overview

The Nexperia 74HCT03PW,112 is a quad 2-input NAND gate featuring open-drain outputs. 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 utilizes TTL input levels and includes clamp diodes for interfacing with voltages exceeding VCC. It complies with JEDEC standards JESD8C and JESD7A, offering ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.

Feature Summary

• Quad 2-input NAND logic function with open-drain output configuration
• TTL-compatible input levels for direct interface with TTL systems
• Wide operating temperature range supporting industrial applications
• High noise immunity and robust latch-up performance

Applications

• General-purpose digital logic processing
• Signal gating and switching circuits
• Interface circuits requiring open-drain pull-down capability

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP14 package variant during procurement. Confirm that the application environment remains within the specified 4.5 V to 5.5 V supply voltage limits. Ensure design safeguards account for the open-drain nature of the outputs, which requires external pull-up resistors for proper HIGH-level operation. Validate thermal management requirements against the specified derating curves for the TSSOP14 package.

Selection Notes

Select this component when TTL logic compatibility is required alongside CMOS low power dissipation characteristics. The open-drain output architecture makes it suitable for wired-AND configurations or level shifting applications where external pull-ups are present. Consider the TSSOP14 package dimensions if space constraints dictate a thin shrink small outline form factor. Verify that the high noise immunity meets the electromagnetic interference requirements of the target system.

Part Context

This part belongs to the 74HCT series of high-speed CMOS logic devices manufactured by Nexperia. The 74HCT series bridges the gap between standard CMOS and TTL logic families by adopting TTL input thresholds while maintaining CMOS output drive capabilities. This specific model integrates four independent NAND gates into a single integrated circuit, providing a compact solution for complex digital logic designs.

FAQ

What is the function of the clamp diodes on the inputs?

The input clamp diodes enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.

How does the open-drain output affect the logic HIGH state?

The open-drain output pulls the signal LOW when active but enters a high-impedance OFF-state otherwise. An external pull-up resistor is required to establish a defined HIGH voltage level.
