HEF4511BP,652

Display Drivers Overview

The HEF4511BP,652 is a BCD-to-7-segment latch/decoder/driver from the NXP HEF4000B series. It features a single 4-to-7 decoding function with non-inverting outputs designed to drive seven-segment displays. The device is housed in a 16-pin Plastic Dual In-line Package (DIP), specifically identified as SOT38-1. It operates within a standard temperature range of -40°C to +85°C and complies with RoHS directives. The component utilizes LOCMOS technology for robust performance in digital logic applications requiring direct display interfacing.

Display Drivers Feature Summary

• Integrates a 4-bit latch, BCD-to-7-segment decoder, and driver in a single functional block
• Provides non-inverting outputs capable of directly driving common-cathode seven-segment displays
• Features active LOW lamp test input for verifying display segment integrity

Display Drivers Applications

• Digital clock and timer display interfaces
• Numeric readouts on industrial control panels
• Consumer electronics alphanumeric indicators

Display Drivers Procurement Notes

Verify the specific suffix '652' corresponds to the required tape-and-reel or bulk packaging configuration as defined by NXP standards. Confirm that the 16-pin DIP form factor aligns with existing PCB footprints. Ensure compliance with environmental regulations such as RoHS is documented for the specific batch. Cross-reference the manufacturer part number against official NXP distribution channels to avoid counterfeit components.

Display Drivers Selection Notes

Select this component when a combined latching and decoding solution is required for seven-segment displays. The HEF4511BP variant offers through-hole mounting suitable for prototyping or high-reliability assemblies. Consider the HEF4511BT if surface-mount technology is preferred. Evaluate power supply requirements and output current capabilities against the specific display type before finalizing the design.

Display Drivers Part Context

This part belongs to the HEF4000B series, which represents a second-generation CMOS logic family from NXP. These devices offer improved noise immunity and lower power consumption compared to earlier iterations. The HEF4511BP specifically addresses the need for stable data retention via its internal latch mechanism, ensuring display content remains static until updated by new input signals.

Display Drivers Replacement Considerations

Direct equivalents include the HEF4511BT,652 for surface-mount applications. Other compatible decoders in the same family are the HEF4513BP for active-low outputs. Verify pin compatibility and electrical characteristics before substituting with generic CMOS alternatives.
