SN74AHC74PW

Flip Flops Overview

The SN74AHC74PW is a dual D-type flip-flop from the Texas Instruments SN74AHC series, housed in a 14-TSSOP surface-mount package. It operates within a supply voltage range of 2V to 5.5V and supports TTL-compatible inputs. The device features two independent circuits with both non-inverting (Q) and inverting (Q') outputs. Key electrical specifications include a maximum propagation delay of 8.8ns at 5V with a 50pF load, and output drive capabilities of 8mA for both high and low states. It functions reliably across an industrial temperature range of -40°C to +125°C.

Flip Flops Feature Summary

• Dual independent D-type flip-flops with complementary Q and Q' outputs
• TTL-compatible input logic levels for direct interfacing
• Wide operating voltage range supporting 2V to 5.5V supplies
• Industrial temperature rating extending to +125°C

Flip Flops Applications

• Parallel data storage and register applications
• Shift register construction
• Timing and synchronization circuits
• State machine implementation

Flip Flops Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-14 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity.

Flip Flops Selection Notes

Select this component when dual edge-triggered storage is required with TTL input compatibility. The AHC series offers faster switching speeds compared to standard HC logic while maintaining similar pinouts. Verify that the 14-TSSOP footprint aligns with PCB layout constraints and thermal requirements for the target application environment.

Flip Flops Part Context

This part belongs to the SN74AHC family of high-speed CMOS logic devices. It serves as a fundamental building block for sequential logic designs. The 'PWR' suffix typically denotes tape-and-reel packaging, whereas 'PW' indicates tube packaging for the same TSSOP-14 physical form factor.

Flip Flops Replacement Considerations

SN74AHC74DR: Same logical function and specifications but packaged in SOIC-14 instead of TSSOP-14. Requires footprint adaptation. SN74AHCT74PW: Similar performance but optimized for 5V operation with stricter TTL thresholds.
