HEF4516BP,652

Counter Dividers Overview

The HEF4516BP,652 is an edge-triggered synchronous 4-bit binary up/down counter manufactured by NXP USA Inc. It operates within a recommended VDD power supply range of 3 V to 15 V referenced to VSS (ground). The device features a clock input (CP), an up/down count control input (UP/DN), an active LOW count enable input (CE), an asynchronous active HIGH parallel load input (PL), four parallel inputs (D0 to D3), and four parallel outputs (Q0 to Q3). It includes an active LOW terminal count output (TC) and an overriding asynchronous master reset input (MR). The component is housed in a DIP16 plastic dual in-line package.

Counter Dividers Feature Summary

• Supports fully static operation for reliable logic processing
• Provides standardized symmetrical output characteristics across operating conditions
• Includes an asynchronous active HIGH parallel load input for direct data entry
• Features an overriding asynchronous master reset input for immediate state clearing

Counter Dividers Applications

• Synchronous digital counting circuits requiring bidirectional capability
• Data storage applications utilizing the parallel load functionality
• Timing and sequencing systems employing the terminal count output

Counter Dividers Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type and compliance status. Confirm that the DIP16 variant matches the required mechanical footprint for the target assembly. Ensure the procurement channel sources directly from authorized distributors to guarantee product authenticity and traceability.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter with both up and down counting capabilities is required. The inclusion of a parallel load feature allows for direct initialization of the count value. Verify that the operating voltage range of 3 V to 15 V aligns with the system power supply design constraints.

Counter Dividers Part Context

This part belongs to the HEF4000B series of CMOS logic integrated circuits produced by NXP Semiconductors. The series is designed for general-purpose digital applications using complementary metal-oxide-semiconductor technology. The HEF4516B specifically implements a 4-bit binary counter architecture within this family.
