CD40174BE

Overview

The CD40174BE is a CMOS Hex D-Type Flip-Flop manufactured by Texas Instruments, belonging to the 4000B series. It features six independent D-type flip-flops within a single 16-pin PDIP package designed for through-hole mounting. The device operates on a supply voltage ranging from 3V to 18V and supports a maximum clock frequency of 16 MHz at 15V. It functions with non-inverting outputs and includes a master reset input. The component is rated for an operating temperature range from -55°C to +125°C.

Feature Summary

• Contains six independent D-type flip-flops in a single integrated circuit
• Features a common master reset input for synchronous clearing of all stages
• Provides non-inverting outputs for direct signal interfacing
• Supports operation across a wide power supply voltage range

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for digital logic systems
• Frequency division applications in timing circuits
• State machine implementation in control logic

Procurement Notes

Verify that the specific part number matches the required 16-pin PDIP package configuration for through-hole assembly. Confirm that the manufacturer designation corresponds to Texas Instruments to ensure compatibility with standard 4000B series electrical characteristics. Check for RoHS compliance status if environmental regulations apply to the final product assembly. Ensure the supplier provides valid traceability documentation for the component batch.

Selection Notes

Select this component when a design requires multiple synchronized storage elements within a compact footprint. The choice is appropriate for applications needing parallel data retention or serial shifting capabilities using standard CMOS logic levels. Consider the 16-pin DIP form factor if PCB layout constraints favor through-hole technology over surface mount alternatives. Evaluate the 16 MHz speed limit against the system clock requirements to ensure reliable switching performance.

Part Context

This device is part of the widely used 4000B series of CMOS logic integrated circuits produced by Texas Instruments. The series is known for its high noise immunity and broad operating voltage range, making it suitable for various general-purpose digital applications. The CD40174BE specifically addresses the need for multi-bit storage within this family, offering a cost-effective solution for complex logic designs requiring multiple flip-flops.

Replacement Considerations

The CD40174BPWR is listed as a direct replacement option, differing primarily in the TSSOP-16 surface-mount package instead of the PDIP-16 through-hole variant. Designers must verify pinout compatibility and physical board space constraints when substituting between these package types.
