CD40175BE

Overview

The CD40175BE is a quad D-type flip-flop from the Texas Instruments 4000 series CMOS logic family. It features four independent D-type flip-flops with clock and clear inputs, packaged in a 16-pin DIP. The device operates within a supply voltage range of 3V to 18V and supports a maximum clock frequency of 11 MHz at 15V. It functions reliably across an extended temperature range of -55°C to +125°C, ensuring stable performance in various industrial and commercial applications.

Feature Summary

• Contains four independent D-type flip-flops for parallel data storage
• Features dedicated clock and asynchronous clear inputs for precise control
• Supports high-speed operation with a maximum clock frequency of 11 MHz
• Operates over a wide supply voltage range from 3V to 18V

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for data transmission
• Frequency division and counting applications
• Digital state memory and latch circuits

Procurement Notes

Verify the package type matches the required PCB footprint, as the BE suffix indicates a through-hole PDIP-16 configuration. Confirm that the operating environment stays within the specified -55°C to +125°C temperature range. Ensure power supply rails do not exceed the 18V maximum limit to prevent device damage. Check for RoHS compliance requirements if applicable to the final assembly standards.

Selection Notes

Select this component when a compact solution for storing four bits of data is required without external gating logic. It is suitable for designs needing synchronous data capture with asynchronous reset capabilities. Consider the PDIP-16 package for prototyping or applications where surface-mount space is not a constraint. Evaluate the 11 MHz speed limit against system clock requirements to ensure timing margins are sufficient.

Part Context

The CD40175BE belongs to the widely used 4000 series of CMOS logic devices, known for their low power consumption and broad voltage compatibility. This specific part provides a standard quad D-flip-flop function, differing from counters like the CD4017 by offering individual data retention rather than sequential output stepping. It serves as a fundamental building block for complex digital systems requiring reliable data latching.

FAQ

What is the function of the Clear input on the CD40175BE?

The Clear input is asynchronous and resets all four flip-flops to a low state immediately, regardless of the clock signal.

Can the CD40175BE operate with a 5V supply?

Yes, the device is rated for a supply voltage range of 3V to 18V, making it compatible with 5V logic systems.
