74AHCT74PW,118

Overview

The 74AHCT74PW,118 is a dual D-type flip-flop with separate clock inputs manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 5.5 V and utilizes TSSOP-14 surface-mount packaging. The device features low static power consumption and high noise immunity characteristic of the AHCT logic family. It supports data retention without continuous clocking and includes dedicated set and reset functions for state control.

Feature Summary

• Dual independent D-type flip-flops with distinct clock inputs
• Compatible with standard CMOS logic levels via HCT input structure
• Low power dissipation suitable for battery-operated applications
• High noise immunity ensuring reliable signal integrity

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for data storage
• Timing delay elements in digital systems
• State machine implementation in control logic

Procurement Notes

Verify component authenticity through official Nexperia channels or authorized distributors. Confirm package marking matches TSSOP-14 specifications. Check datasheet revisions for any pinout or electrical parameter updates. Ensure handling procedures comply with ESD protection standards during assembly.

Selection Notes

Select this component when dual isolated flip-flops are required within a single package. The AHCT series ensures compatibility with 5 V CMOS systems while accepting TTL-compatible inputs. Consider thermal performance and PCB layout requirements for TSSOP-14 packages in high-density designs.

Part Context

This part belongs to the 74AHCTxx family of advanced high-speed CMOS logic devices. It provides enhanced speed compared to standard HC series while maintaining pin-for-pin compatibility with HCT inputs. The PW suffix indicates the TSSOP package variant offered by Nexperia.

Replacement Considerations

Cross-reference with other manufacturers' 74AHCT74 equivalents such as SN74AHCT74 from Texas Instruments or MC74AHCT74 from onsemi. Verify identical pin configuration and electrical characteristics before substitution.
