HEF4518BT** is a dual BCD up-counter IC manufactured by **NXP Semiconductors (formerly Philips, hence the "PHI" designation)**.

The HEF4518BT is a dual BCD up-counter IC manufactured by NXP Semiconductors (formerly Philips, hence the "PHI" designation).

Specifications:

  • Type: Dual BCD Up-Counter
  • Logic Family: CMOS (HEF4000 series)
  • Supply Voltage Range: 3V to 15V
  • Operating Temperature Range: -40°C to +85°C
  • Package: SO16 (Surface Mount)
  • Propagation Delay: Typically 200ns at 5V
  • Input/Output Compatibility: TTL-compatible at 5V
  • Reset Function: Asynchronous master reset

Description:

The HEF4518BT consists of two identical 4-bit synchronous BCD counters with individual clock inputs (CP), enable inputs (EN), and asynchronous reset (MR). Each counter can operate independently.

Features:

  • Dual BCD Counter: Two independent counters in one package
  • Synchronous Counting: Counts on clock rising or falling edge (configurable)
  • Asynchronous Reset: Immediate reset via MR pin
  • Wide Voltage Range: Supports 3V to 15V operation
  • Low Power Consumption: CMOS technology ensures low power dissipation
  • High Noise Immunity: Typical for HEF4000 series ICs

This IC is commonly used in frequency division, time-delay circuits, and digital counting applications.
