74VHC273MTCX

Overview

The onsemi 74VHC273MTCX is an octal D-type flip-flop with positive-edge triggering, housed in a 20-TSSOP surface-mount package. It operates within a supply voltage range of 2 V to 5.5 V and supports a maximum clock frequency of 110 MHz. The device features single-ended inputs and outputs with non-inverting polarity. Key electrical specifications include a propagation delay of 17.1 ns at typical conditions, output drive currents of ±8 mA, and a static current (Iq) of 4 µA. It functions reliably across an operating temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration. Confirm that the component meets RoHS3 compliance requirements for your target market. Cross-reference the datasheet revision history to validate the electrical parameters and pinout assignments prior to finalizing procurement orders.

Selection Notes

Select this component when an octal D-type flip-flop with high-speed operation and moderate drive strength is required. The 74VHC series offers faster switching speeds compared to standard HC logic while maintaining compatibility with 5V and lower voltage systems. Ensure the application design accommodates the 20-TSSOP package dimensions and thermal characteristics for reliable surface-mount assembly.

Part Context

This part belongs to the 74VHC family of high-speed CMOS logic devices manufactured by onsemi. It serves as a direct functional equivalent to other octal D-type flip-flops within the industry-standard 74xx logic nomenclature. The device integrates eight independent D-type flip-flops into a single integrated circuit, providing efficient space-saving solutions for complex digital signal processing tasks.

Replacement Considerations

The part number alias 74VHC273MTCX_NL indicates a potential alternative sourcing designation from the same manufacturer.
