SN74HCT74DBR

Flip Flops Overview

The SN74HCT74DBR is a dual D-type flip-flop manufactured by Texas Instruments, belonging to the SN74HCT74 logic series. It features positive-edge triggering with set and reset inputs, housed in a 14-pin TSSOP surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V, supporting a maximum clock frequency of 46 MHz. Key electrical characteristics include a propagation delay of 25 ns at 5.5 V with a 50 pF load, output currents of ±4 mA, and a static current of 4 µA. It functions reliably across an operating temperature range from -40°C to +85°C.

Flip Flops Procurement Notes

Verify that the ordering suffix 'DBR' corresponds specifically to the TSSOP-14 package variant rather than other packaging options like tube or reel configurations. Confirm RoHS compliance status and ensure the component meets the required industrial temperature specifications for the intended application environment before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with set and reset functionality is required in a compact surface-mount form factor. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage range and verify that the 46 MHz maximum clock frequency aligns with system timing requirements. Consider the TSSOP-14 footprint constraints during PCB layout planning.
