CD40175BNS

Overview

The CD40175BNS is a CMOS logic integrated circuit manufactured by Texas Instruments, belonging to the 4000B series. It functions as a quad D-type flip-flop with positive-edge triggering and includes a master reset input. The device is housed in a 16-pin Small Outline Integrated Circuit (SOIC) package with a width of 5.30 mm. It operates within a supply voltage range of 3 V to 18 V and supports a maximum clock frequency of 14 MHz. The component features a propagation delay of 120 ns at 15 V with a 50 pF load, a static current consumption of 4 µA, and an output drive capability of 6.8 mA for both high and low states. It is rated for an operating temperature range from -55°C to +125°C.

Feature Summary

• Integrates four independent D-type flip-flops with positive-edge clock triggering within a single unit.
• Features a dedicated master reset input that synchronously clears all flip-flop outputs.
• Provides complementary outputs for each flip-flop stage to support diverse logic interfacing requirements.

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations in digital systems
• Event counting and sequence generation logic

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the selected variant matches the required package type and temperature rating for the target application environment. Cross-reference datasheet specifications for timing parameters before integration into high-speed designs.

Selection Notes

Select this component when a compact solution for quadruple D-type storage is required within standard CMOS logic families. Consider the 14 MHz maximum clock speed and 120 ns propagation delay for timing constraints. Evaluate the 3 V to 18 V supply range against system power availability and ensure the SOIC package fits the PCB layout constraints.
