74HC273DB,112

Overview

The 74HC273DB,112 is an octal D-type flip-flop manufactured by Nexperia. It belongs to the HC logic family and features positive-edge triggering with a master reset input. The device operates within a supply voltage range of 2.0 V to 6.0 V. It utilizes a SOIC-20 surface-mount package. Key electrical parameters include a propagation delay of 25 ns at 5 V and output drive currents of 5.2 mA. The component supports operation across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Octal configuration providing eight independent positive-edge triggered D-type flip-flops sharing a common clock and master reset line.
• High noise immunity and low power dissipation characteristics inherent to CMOS technology.
• Robust latch-up performance exceeding 100 mA per JESD 78 Class II Level B standards.

Applications

• Data storage registers in digital systems
• Shift register implementations
• Parallel-to-serial data conversion circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for Product Change Notifications (PCN) regarding package or material updates. Ensure the specific suffix matches required packaging options. Validate that the source document corresponds to the exact part number to avoid substitution errors.

Selection Notes

Select this component when an octal edge-triggered storage element is required within the HC logic family. Consider the 2.0 V to 6.0 V operating range for compatibility with various supply rails. Evaluate the SOIC-20 package dimensions against PCB space constraints. Compare propagation delays and drive capabilities against system timing requirements.

Part Context

This part is part of the standard 74HC series of octal flip-flops. It serves as a fundamental building block for sequential logic circuits. The DB variant denotes the specific SOIC-20 plastic small outline package. It complements other logic families like HCT and AHC for different voltage and speed applications.

Replacement Considerations

Compatible substitutes include the 74HC273D,118 and 74HC273N. Verify pinout compatibility and electrical specifications before substitution. Ensure the alternative part meets the same voltage and temperature requirements.
