74HC273FPDV-E

Overview

The HD74HC273FPDV-E is an octal D-type flip-flop manufactured by Renesas Electronics Corporation. It belongs to the HC/UH series and features positive edge triggering with true outputs. The device contains eight master-slave flip-flops sharing a common clock and a common clear input. Data from the D inputs is transferred to the Q outputs on the low-to-high transition of the clock signal, provided setup and hold times are met. A low-level clear input forces all outputs to a low state. The component is housed in a plastic DIP-20 package.

Feature Summary

• Contains eight master-slave flip-flops with a common clock and common clear input
• Transfers data to outputs on the low to high transition of the clock input
• Sets all outputs to a low state when the clear input is low

Applications

• Octal storage registers
• Offset buffers
• Working memory

Procurement Notes

Verify the specific ordering suffix 'FPDV' against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Ensure the part number matches the current Renesas product list, as suffixes can indicate variations in packaging or lead finish that do not alter the core logic function. Cross-reference the RoHS compliance status and lead-free designation with the latest datasheet revision.

Selection Notes

Select this component for designs requiring octal data storage with a global reset capability. The HC series offers wide operating voltage ranges suitable for various digital logic applications. Consider the propagation delay and output drive current requirements relative to the load capacitance. Verify that the DIP-20 through-hole package aligns with the PCB layout constraints and assembly processes.

Part Context

This part is part of the HD74HC273 family of octal D-type flip-flops. It is functionally compatible with other standard 74HC273 devices from different manufacturers, though pinout and electrical characteristics should be verified. The device is designed for general-purpose digital logic applications requiring parallel data storage and synchronization.

Replacement Considerations

Compatible substitutes include the HD74HC273P (DIP-20) and HD74HC273RPEL (SOP-20). Other manufacturers offer equivalent parts such as the SN74HC273N. Verify package dimensions and electrical parameters before substitution.
