HEF4515BP,652

Overview

The HEF4515BP,652 is a dual addressable latch manufactured by NXP USA Inc., belonging to the HEF4000B series. It features a plastic dual in-line package (PDIP) with 16 pins for through-hole mounting. The device operates within a supply voltage range of 3 V to 15 V and supports an operating temperature range from -40 °C to +85 °C. Key electrical parameters include a maximum propagation delay of 70 ns at 10 V and 55 ns at 15 V, measured under a 50 pF load condition. Output drive capabilities are specified with a maximum low-level output current of 3.6 mA and a maximum high-level output current of -3.6 mA.

Feature Summary

• Dual addressable latch architecture providing independent data storage channels
• Retains stored state information until explicitly overwritten or cleared
• Supports direct asynchronous clear functionality for immediate state reset

Applications

• Data storage circuits requiring parallel input and serial output conversion
• Address decoding systems in digital logic interfaces
• Memory buffer stages in microprocessor peripheral control

Procurement Notes

Verify component authenticity against official NXP datasheets prior to integration. Confirm that the PDIP-16 package variant matches your PCB footprint requirements. Ensure supply chain sources provide traceability documentation consistent with automotive or industrial grade specifications if applicable. Cross-reference the specific suffix codes to validate manufacturing origin and compliance standards before finalizing procurement orders.

Selection Notes

Select this component when dual independent latching is required within a single integrated circuit. The wide supply voltage range accommodates various logic families. Consider the PDIP package constraints regarding board space compared to surface-mount alternatives. Evaluate propagation delay specifications against system clock speeds to ensure timing margins are sufficient for reliable operation under worst-case temperature conditions.

Part Context

This part belongs to the HEF4000B series of CMOS logic devices produced by NXP. The series is characterized by high noise immunity and broad power supply compatibility. The HEF4515 specifically addresses applications needing multiple latched outputs controlled by common clock and clear signals. It serves as a fundamental building block for sequential logic designs in consumer and industrial electronics.

Replacement Considerations

Check for pin-compatible equivalents within the same HEF4000 family. Verify functional equivalence regarding latch type and clear mechanisms. Ensure replacement packages match physical dimensions and thermal characteristics.
