CD40175BMT

Overview

The CD40175BMT is a quad D-type flip-flop manufactured by Texas Instruments, belonging to the 4000B CMOS logic series. It features four independent D-type flip-flops with positive-edge triggering and a master reset function. The device operates within a supply voltage range of 3V to 18V and supports a clock frequency up to 14 MHz. It utilizes a 16-SOIC surface-mount package with a width of 3.90mm. Key electrical parameters include a maximum propagation delay of 120ns at 15V with 50pF load, output currents of ±6.8mA, and a static current (Iq) of 4µA. The operating temperature range spans from -55°C to 125°C.

Feature Summary

• Contains four independent D-type flip-flops with positive-edge clock triggering
• Features a dedicated master reset input for synchronous clearing of all stages
• Provides complementary outputs for each flip-flop stage
• Supports wide supply voltage operation from 3V to 18V

Applications

• Parallel-to-serial data conversion circuits
• Digital sequence generation and control logic
• High-speed shift register applications requiring low power consumption
• Event counting and timing sequences in digital systems

Procurement Notes

Verify the specific suffix 'BMT' corresponds to the tape-and-reel packaging format as indicated by distributor listings. Confirm RoHS compliance status, noting that some sources indicate RoHS3 compliance while others may list older variants. Ensure the supplier documentation explicitly references the Texas Instruments manufacturer part number CD40175BMT to avoid confusion with similar SOIC packages or non-TI equivalents. Check for any recent Product Change Notifications regarding pinout or electrical specification updates.

Selection Notes

Select this component when a compact surface-mount solution for quad D-type storage is required. The 16-SOIC package offers a balance between board space efficiency and thermal performance compared to larger packages. Consider the 120ns propagation delay and 14MHz clock limit for high-speed design constraints. The wide voltage range allows flexibility in system power architecture, while the low static current makes it suitable for battery-powered or energy-efficient designs.

Part Context

The CD40175BMT is part of the extensive 4000B CMOS logic family from Texas Instruments, designed for general-purpose digital logic applications. It serves as a fundamental building block for sequential logic circuits. The 'B' suffix typically denotes improved specifications or manufacturing processes within the legacy 4000 series lineup. This specific variant focuses on surface-mount integration, facilitating automated assembly in modern PCB manufacturing environments.

Replacement Considerations

CD40175BM: Same functional device in standard tube packaging instead of tape-and-reel.

FAQ

What is the trigger type for the CD40175BMT flip-flops?

The flip-flops are triggered on the positive edge of the clock signal.

Does the CD40175BMT have individual resets or a master reset?

It features a single master reset input that clears all four flip-flops simultaneously.
