CD74HCT174E

Overview

The CD74HCT174E is a high-speed CMOS logic device containing six D-type flip-flops. It operates within a supply voltage range of 2.0 V to 6.0 V and features TTL-compatible inputs. The component provides non-inverting outputs with a typical propagation delay of 25 ns at 5 V. It is housed in a 16-pin PDIP package and supports through-hole mounting. The device functions as positive-edge-triggered storage elements, suitable for parallel-to-serial conversion and data register applications.

Feature Summary

• Contains six independent D-type flip-flops for data storage
• Positive-edge triggering mechanism for clock synchronization
• TTL-compatible input thresholds for broad interface compatibility
• High-speed CMOS technology ensuring low power consumption

Applications

• Parallel-to-serial data conversion circuits
• General-purpose data registers
• Shift register configurations
• Timing control logic systems

Procurement Notes

Verify the specific suffix 'E' corresponds to the PDIP-16 package and lead-free compliance when ordering. Confirm that the required operating temperature range aligns with commercial or industrial specifications. Ensure input signal levels match TTL standards to guarantee proper logic threshold recognition during operation.

Selection Notes

Select this component when six synchronized D-type storage elements are required in a single package. Consider the HCT series for direct interfacing with TTL logic families without additional level shifting. Evaluate the PDIP package for prototyping or applications requiring through-hole assembly methods over surface mount alternatives.

Part Context

This part belongs to the Texas Instruments CD74HCT174 family of high-speed CMOS logic devices. It is functionally compatible with other 74HCT series components, allowing mixed logic family integration. The device serves as a standard building block for sequential logic designs requiring multiple flip-flop stages in compact integrated circuit form factors.

Replacement Considerations

CD74ACT174E offers faster switching speeds but requires different voltage considerations. CD74HC174N provides similar functionality with HC input characteristics instead of HCT. Verify pinout compatibility and electrical parameters before substituting to ensure circuit integrity.
