74HCT00D,652

Overview

The Nexperia 74HCT00D,652 is a quad 2-input NAND gate from the HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a 14-lead SOIC (SOT108-1) package with a body width of 3.9 mm. The device features TTL-compatible input levels and CMOS low power dissipation. Static characteristics specify a maximum HIGH-level output voltage of 3.7 V at -4.0 mA load and a LOW-level output voltage of 0.4 V at 4.0 mA load. Dynamic performance includes a propagation delay of up to 29 ns at 4.5 V with 50 pF load capacitance.

Feature Summary

• Provides four independent 2-input NAND logic functions in a single integrated circuit
• Features inputs compatible with standard TTL logic voltage levels
• Includes internal clamp diodes on all inputs for interfacing with voltages exceeding VCC
• Offers high noise immunity and robust latch-up protection exceeding 100 mA

Applications

• Digital signal processing circuits requiring basic Boolean logic operations
• Interface modules connecting TTL-level sources to CMOS-level destinations
• General-purpose logic control systems operating at 5 V supply rails

Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and temperature range specifications. Ensure that the procurement source provides valid RoHS compliance declarations consistent with the latest product data sheet revisions. Confirm availability status directly with authorized distributors as manufacturing statuses may change without prior notice.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS output drive capabilities. The 74HCT00D variant is appropriate for designs utilizing the SOIC-14 surface-mount footprint. Verify that the application environment remains within the specified -40 °C to +125 °C operating temperature range to ensure reliable performance.

Part Context

This part belongs to the Nexperia 74HCT series, which bridges the gap between older TTL standards and modern CMOS technologies. The 'D' designation specifically identifies the plastic small outline package variant. This family is widely used in legacy system upgrades where pin compatibility with original TTL designs is maintained while benefiting from improved power efficiency.

Replacement Considerations

The 74HCT00D,653 is listed as a parameter-equivalent alternative by the manufacturer.
