74HC273PW,118

Overview

The 74HC273PW,118 is an octal D-type flip-flop with reset manufactured by Nexperia. It operates within a supply voltage range of 2 V to 6 V and features eight D inputs and corresponding Q outputs. The device utilizes a TSSOP-20 surface-mount package (SOT360). Key electrical specifications include a propagation delay of 50 ns, a maximum static current of 4 µA, and output drive capabilities of -8 mA for low level and 8 mA for high level. It supports industrial temperature ranges from -40 °C to +125 °C.

Feature Summary

• Provides synchronous data storage functionality through eight independent D-type flip-flops with a common clock input.
• Includes a dedicated asynchronous reset input that forces all outputs to a low state independently of the clock signal.
• Features CMOS construction ensuring low power dissipation and high noise immunity suitable for various logic families.

Applications

• General-purpose digital data storage and buffering in embedded systems.
• Parallel-to-serial data conversion circuits requiring temporary holding registers.
• State machine implementations in microcontroller peripheral interfaces.

Procurement Notes

Verify the specific suffix 118 corresponds to the TSSOP-20 package configuration when sourcing. Confirm RoHS compliance status via official documentation prior to integration. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity. Cross-reference pinout diagrams with target PCB footprint to prevent orientation errors during placement.

Selection Notes

Select this component when an octal register with a global reset is required within a 2 V to 6 V operating window. Compare against LVC or AHC series variants if lower voltage operation or faster switching speeds are necessary. Evaluate package constraints to ensure TSSOP-20 fits the available board space. Consider thermal performance requirements given the specified power dissipation limits.

Part Context

This part belongs to the standard 74HC logic family, widely used for general-purpose digital applications. It complements other Nexperia logic components like buffers and decoders. The PW suffix indicates the plastic TSSOP package type, while 118 denotes the specific reel packaging configuration for automated assembly processes.

Replacement Considerations

Direct substitutes include 74HC273D,118 for SOIC package compatibility. Alternative packages such as SSOP may require mechanical adaptation. Verify pin compatibility before replacing with generic equivalents from other manufacturers.
