74HC03N,652

Overview

The 74HC03N,652 is a quad 2-input NAND gate with open-drain outputs manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features CMOS input levels and includes clamp diodes on inputs for interfacing with voltages exceeding VCC. Propagation delay is specified at 19 ns maximum at 4.5 V and 25 ns maximum at 6.0 V under standard load conditions.

Feature Summary

• Quad 2-input NAND logic function with open-drain output configuration
• CMOS compatible input levels with integrated input clamp diodes
• Extended industrial operating temperature range up to +125 °C
• ESD protection exceeding 2000 V via Human Body Model testing

Applications

• General digital logic processing in consumer electronics
• Industrial control systems requiring wide temperature tolerance
• Computing equipment interface circuits

Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and availability status. Confirm RoHS compliance details directly with the manufacturer as regulatory statuses may change. Ensure design compatibility with open-drain requirements before procurement.

Selection Notes

Select this component when a quad NAND gate with open-drain outputs is required for wired-AND configurations or level shifting. Verify that the CMOS input thresholds align with the driving source logic family. Consider the thermal derating characteristics if operating near the upper temperature limit.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices produced by Nexperia. The series provides performance comparable to the older 74LS TTL family while offering lower power consumption and wider supply voltage flexibility. The 'N' designation typically indicates a through-hole DIP package variant.

Replacement Considerations

Direct functional equivalents include the 74HCT03 for TTL-compatible inputs. Other manufacturers offer pin-compatible alternatives such as the SN74HC03N. Verify package dimensions and electrical specifications against the original datasheet before substitution.
