MC14516BCPG

Counter Dividers Overview

The MC14516BCPG is a synchronous up/down binary counter manufactured by onsemi in a PDIP-16 package. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports an ambient temperature range from -55 °C to +125 °C. The device features asynchronous preset enable, single-pin reset, and diode protection on all inputs. It counts on the positive edge of the clock signal and includes carry in/out pins for cascading applications.

Counter Dividers Feature Summary

• Synchronous up/down counting capability controlled by a dedicated direction input
• Asynchronous parallel preset loading via active-high preset enable pin
• Single-pin asynchronous reset function that clears outputs to low state
• Input protection diodes integrated across all logic terminals

Counter Dividers Applications

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

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'G' confirms lead-free packaging status as defined in the manufacturer's documentation. Confirm the PDIP-16 physical dimensions match the CASE 648 specification sheet. Ensure the component meets RoHS compliance requirements for your target assembly process before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a synchronous binary counter with independent up/down control is required. The wide operating voltage range allows compatibility with various logic families. Consider the asynchronous nature of the preset and reset functions when designing timing-critical sequences. Verify that the load capacitance requirements align with the specified propagation delay characteristics.

Counter Dividers Part Context

This part belongs to the MC14516B family of CMOS binary counters. It is constructed using P-channel and N-channel enhancement mode devices in a monolithic structure. The device is designed to drive two Low-Power TTL loads or one Low-Power Schottky load over the rated temperature range.

Counter Dividers FAQ

How is the counting direction determined?

The direction is controlled by the UP/DOWN input pin; applying a high level enables up counting, while a low level enables down counting.

What triggers the output state changes?

Output states change on the positive transition of the clock input signal.

How are multiple counters connected for extended bit counts?

Cascading is achieved by connecting the Carry Out of one stage to the Carry In of the next stage while clocking each counter in parallel.
