CD74AC174PWR

Overview

The CD74AC174PWR is a hex D-type flip-flop manufactured by Texas Instruments, belonging to the SN74AC logic family. It features six independent D-type flip-flops with positive-edge triggering and an asynchronous clear input. The device operates within a supply voltage range of 1.5 V to 6 V and supports data rates up to 95 MHz. It is housed in a 16-pin TSSOP package and is rated for operation from -55°C to +125°C.

Feature Summary

• Hex configuration providing six independent D-type flip-flops in a single package
• Positive-edge triggered clocking mechanism for synchronous data capture
• Asynchronous clear function for immediate output reset regardless of clock state
• Wide operating voltage range supporting low-power system designs

Applications

• Parallel-to-serial and serial-to-parallel data conversion circuits
• Shift register implementations for data storage and transfer
• Digital counters and timing sequence generators
• Memory buffer stages in microprocessor interfacing systems

Procurement Notes

Verify the specific suffix PWR indicates the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component meets automotive or industrial temperature ratings if required by the final application environment. Cross-reference datasheet revisions to confirm pinout consistency with existing board layouts.

Selection Notes

Select this component for applications requiring high-speed digital storage with wide voltage flexibility. The AC logic family offers faster propagation delays compared to standard HC series devices. Consider the TSSOP package for surface-mount assembly constraints. Evaluate power consumption requirements against the CMOS technology characteristics at the target operating frequency.

Part Context

This part belongs to the Texas Instruments SN74AC series of advanced CMOS logic devices. The AC series provides performance levels between standard TTL and older CMOS technologies. The CD74AC174 specifically addresses needs for hex flip-flop functionality in compact surface-mount form factors. It serves as a core building block for sequential logic design in modern electronic systems.

Replacement Considerations

CD74AC174PWRE4 is an equivalent lead-free variant within the same product line. SN74AC174PWR is the commercial grade equivalent with identical electrical specifications. Verify package compatibility and thermal performance when substituting across different manufacturing batches.
