CD40175BM

Overview

The CD40175BM is a Texas Instruments CMOS integrated circuit belonging to the 4000B series. It functions as a quad D-type flip-flop with a master reset input, housed in a 16-pin SOIC surface-mount package. The device operates on a supply voltage range of 3V to 18V and supports clock frequencies up to 14 MHz. Key electrical characteristics include a maximum propagation delay of 120ns at 15V with 50pF load, static current of 4 µA, and output currents of 6.8mA for both high and low states. It features non-inverting outputs and operates within a temperature range of -55°C to 125°C.

Feature Summary

• Integrates four independent positive-edge-triggered D-type flip-flops within a single package.
• Features a dedicated master reset input that synchronously clears all flip-flop outputs.
• Provides complementary (non-inverting) outputs for each flip-flop stage.

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations
• Digital sequence generation systems

Procurement Notes

Verify the specific suffix '96' or 'G4' against the required RoHS compliance status and packaging type (Tape & Reel vs. Cut Tape). Confirm the active status of the component, as some variants may be discontinued. Ensure the SOIC-16 package width matches the PCB footprint requirements before ordering.

Selection Notes

Select this component when a compact solution for storing four bits of data is required. Consider the 14 MHz clock limit and 120ns propagation delay for timing constraints. Compare against other 4000B series logic if higher speed or different output types are needed. Verify power supply stability within the 3V to 18V range.

Part Context

This part is part of the standard 4000B CMOS logic family, known for wide voltage operation and compatibility with various digital systems. It serves as a fundamental building block for sequential logic design, offering a cost-effective alternative to faster TTL or advanced CMOS families for lower-speed applications.

FAQ

What is the function of the master reset pin?

The master reset pin asynchronously clears all four flip-flops, forcing all outputs to a low state regardless of the clock signal.

Does the CD40175BM have inverted outputs?

No, the CD40175BM provides non-inverting outputs for each of the four D-type flip-flops.
