MC14516BD

Counter Dividers Overview

The MC14516BD is a synchronous up/down binary counter manufactured by onsemi. It features a 4-bit architecture with parallel preset inputs and asynchronous reset functionality. The device operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports clock frequencies up to 8 MHz at 15 V. It utilizes edge-triggered logic for counting transitions and includes carry in/out pins for cascading multiple stages.

Counter Dividers Feature Summary

• Synchronous up/down binary counting controlled by a dedicated direction input
• Asynchronous preset enable allows immediate loading of parallel data values
• Single-pin asynchronous reset capability for clearing outputs to low state
• Built-in diode protection on all inputs to guard against static discharge

Counter Dividers Applications

• Frequency synthesizer applications requiring low power dissipation
• Analog-to-Digital and Digital-to-Analog conversion circuits
• Programmable frequency divider configurations
• Magnitude and sign generation systems

Counter Dividers Procurement Notes

Verify the specific package suffix (D, F, or P) matches the required footprint, as the base part number covers multiple physical formats. Confirm RoHS compliance status if lead-free materials are mandatory for the assembly process. Check for any recent product change notices regarding pinout or electrical parameter updates before finalizing the design.

Counter Dividers Selection Notes

Select this component when a synchronous binary counter with both up and down counting capabilities is required. Ensure the operating voltage aligns with the 3V to 18V specification. Consider the propagation delay characteristics relative to the system clock speed. Verify that the load capacitance requirements fall within the specified switching time limits for reliable operation.

Counter Dividers Part Context

This device belongs to the MC14516B series of CMOS logic counters. It is designed for general-purpose digital counting tasks where precise synchronization and programmable preset values are necessary. The monolithic MOS structure provides high noise immunity and low static power consumption compared to older logic families.
