CD40175BEX

Overview

The CD40175BEX is a CMOS quad D-type flip-flop manufactured by Harris Corporation, belonging to the 4000 series. It features four independent positive-edge-triggered D-type latches with complementary outputs in a 16-pin DIP package. The device operates within a supply voltage range of 3V to 18V and supports clock frequencies up to 14 MHz. It exhibits a quiescent current of approximately 20 µA and functions reliably across an extended temperature range from -55°C to 125°C.

Feature Summary

• Contains four independent D-type flip-flops with positive edge triggering
• Provides both true and inverted outputs for each latch
• Operates over a wide supply voltage range of 3V to 18V
• Supports high-speed clocking up to 14 MHz

Applications

• Parallel data storage and buffering
• Shift register construction
• Timing and control logic circuits
• State machine implementation

Procurement Notes

Verify component authenticity due to obsolete status and potential marketplace availability. Confirm manufacturer origin as Harris Corporation rather than Texas Instruments or other vendors. Check datasheet revisions for electrical parameter consistency. Ensure packaging matches 16-DIP specifications. Validate operating temperature ratings against application requirements.

Selection Notes

Select this component when requiring multiple D-type flip-flops in a single package with complementary outputs. Consider the wide voltage range for flexible power supply designs. Evaluate the 14 MHz speed capability against system timing requirements. Assess the extended temperature range suitability for industrial environments.

Part Context

The CD40175BEX belongs to the standard 4000 series CMOS logic family, known for high noise immunity and low power consumption. As a quad D-type flip-flop, it serves as a fundamental building block for sequential logic circuits. The device represents legacy technology from Harris Corporation, now largely superseded by modern alternatives but still relevant for specific compatibility needs.

Replacement Considerations

CD40175BE is a compatible variant with similar specifications. CD40175BPWR offers surface mount TSSOP-16 packaging from Texas Instruments. Verify pinout compatibility and electrical characteristics before substitution.
