CD40117BPWR

Specialty Logic Overview

The CD40117BPWR is a CMOS synchronous decade counter and frequency divider manufactured by Texas Instruments. It features ten decoded outputs, allowing sequential activation of output lines upon clock pulses. The device operates within a supply voltage range of 3V to 18V and supports a maximum clock frequency of 5.5 MHz. It includes dedicated carry-in and carry-out terminals for cascading multiple units to form larger modulus counters. The component is housed in a 14-lead thin shrink small-outline package (TSSOP) and is rated for an operating temperature range from -55°C to 125°C.

Specialty Logic Feature Summary

• Synchronous decade counting with ten mutually exclusive decoded outputs
• Dedicated carry-in and carry-out pins for cascading applications
• Asynchronous reset input for immediate initialization

Specialty Logic Applications

• Sequential control circuits
• Frequency division networks
• Cascaded digital counters

Specialty Logic Procurement Notes

Verify the specific package suffix against the manufacturer's latest Package Option Addendum to ensure compatibility with design constraints. Confirm that the RoHS status and lead finish match the project requirements. Check the current marketing status to confirm availability for new designs. Ensure the ordering information aligns with the exact pin count and thermal specifications required.

Specialty Logic Selection Notes

Select this component when a synchronous decade counter with decoded outputs is required. Verify that the operating voltage falls within the specified 3V to 18V range. Consider the 5.5 MHz maximum clock frequency limit for high-speed timing applications. Ensure the TSSOP package dimensions fit the available PCB space. Evaluate the need for cascading capabilities provided by the carry terminals.

Specialty Logic Part Context

This part belongs to the CD4000B series of CMOS logic devices. It functions as a synchronous decade counter, distinct from asynchronous ripple counters. The 'PWR' suffix indicates a thin shrink small-outline package variant. It is designed for general-purpose digital logic applications requiring precise sequencing or frequency division.

Specialty Logic FAQ

What is the function of the carry terminals?

The carry-in and carry-out terminals allow multiple CD40117BPWR units to be connected in series to create counters with moduli greater than ten.

How does the reset mechanism work?

The device features an asynchronous reset input that immediately clears all outputs to a low state regardless of the clock signal.
