74HCT03D,653

Overview

The Nexperia 74HCT03D,653 is a quad 2-input NAND gate with 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 a 14-lead SO plastic small outline package (SOT108-1). Static characteristics specify a low-level output voltage of 0.4 V maximum at 4.0 mA load current. Dynamic performance includes a propagation delay of 36 ns maximum at 4.5 V.

Feature Summary

• Features open-drain outputs suitable for wired-AND configurations
• Includes input clamp diodes for interfacing with voltages exceeding VCC
• Complies with JEDEC standards JESD8C and JESD7A
• Provides high noise immunity and robust latch-up protection

Applications

• General-purpose digital logic circuits requiring NAND functionality
• Bus-oriented applications utilizing open-drain pull-up capabilities
• Interface circuits connecting TTL-level inputs to CMOS systems

Procurement Notes
