CD40175BNSR

Overview

The CD40175BNSR is a CMOS quad D-type flip-flop manufactured by Texas Instruments. It features four independent D-type flip-flops with positive-edge triggering and a master reset input. The device operates within a supply voltage range of 3V to 18V, supporting clock frequencies up to 14 MHz. It utilizes a 16-SOIC surface-mount package and offers high-level and low-level output currents of 6.8 mA each. The component functions across an extended temperature range from -55°C to +125°C.

Feature Summary

• Contains four independent D-type flip-flops with positive-edge clock triggering
• Includes a dedicated master reset input for synchronous clearing of all stages
• Provides complementary outputs for each flip-flop stage

Applications

• High-speed serial-to-parallel data conversion circuits
• Register arrays for temporary data storage in digital systems
• Shift register configurations for sequential logic operations

Procurement Notes

Verify the specific suffix 'SR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 16-SOIC footprint matches the target PCB layout dimensions. Ensure the selected variant meets the necessary RoHS compliance standards for the intended market regulations.

Selection Notes

Select this component when a compact surface-mount solution for multiple D-type storage elements is required. Consider the 14 MHz maximum clock frequency and 6.8 mA drive capability against system timing and load requirements. Evaluate the wide operating temperature range suitability for industrial or automotive environments compared to commercial-grade alternatives.
