CD40175BEE4

Overview

The CD40175BEE4 is a quad D-type flip-flop from the Texas Instruments 4000B CMOS logic series. It features four independent positive-edge-triggered D-type flip-flops with complementary outputs and an active-low master reset input. The device operates within a supply voltage range of 3 V to 18 V, supporting clock frequencies up to 14 MHz. Key electrical parameters include a maximum propagation delay of 120 ns at 15 V with 50 pF load, static current of 4 µA, and output currents of ±6.8 mA. It is available in a 16-SOIC package and functions across a temperature range of -55°C to 125°C.

Feature Summary

• Contains four independent positive-edge-triggered D-type flip-flops with complementary outputs
• Features an active-low master reset input for synchronous clearing of all flip-flops
• Supports wide power supply operation ranging from 3 V to 18 V
• Provides high noise immunity and low static power consumption typical of CMOS technology

Applications

• Data storage and register applications requiring parallel data latching
• Shift register configurations for serial-to-parallel or parallel-to-serial conversion
• Timing control circuits utilizing edge-triggered state retention
• Digital signal processing systems requiring reliable data holding elements

Procurement Notes

Verify that the ordering suffix 'E4' confirms compliance with RoHS 3 standards and lead-free manufacturing processes as specified by Texas Instruments. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Confirm that the 16-SOIC package dimensions match the design footprint requirements. Check for any specific handling instructions related to moisture sensitivity level 1.

Selection Notes

Select the CD40175BEE4 when a compact solution for storing four bits of data is required without external wiring complexity. This part is suitable for designs needing complementary outputs for differential signaling or direct driving of logic gates. Consider the 120 ns propagation delay for timing constraints and the 14 MHz clock limit for speed requirements. The wide voltage range allows flexibility in power supply design compared to fixed-voltage logic families.

Part Context

The CD40175BEE4 belongs to the Texas Instruments 4000B series, which represents an enhanced version of the standard 4000B CMOS logic family. This series offers improved performance characteristics over earlier iterations while maintaining pin compatibility. The 'E4' suffix denotes environmental compliance, specifically adhering to RoHS 3 directives. It serves as a fundamental building block for sequential logic circuits in industrial and consumer electronics.

Replacement Considerations

The CD40175BM96 and CD40175BNSR are confirmed functional substitutes within the same product line. These alternatives share identical logical functionality and pinout configurations. Verify package width differences between SOIC variants if board space is constrained. Ensure that the replacement part number includes the appropriate suffix for desired packaging and environmental compliance.
