74HCT7273N,112

Overview

The 74HCT7273N,112 is an octal D-type flip-flop belonging to the HCT logic family. It features eight positive-edge triggered D inputs and corresponding Q outputs with a master reset function. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 16 ns and a low-level output current capability of 4 mA. It is housed in a DIP-20 package and supports through-hole mounting. The component functions reliably across an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit.
• Positive-edge triggering mechanism synchronized by a common clock input for data capture.
• Master reset functionality that forces all outputs to a LOW state independently of clock and data signals.

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Memory buffer storage applications

Procurement Notes

Verify the specific suffix '112' to confirm the DIP-20 through-hole package variant. Confirm RoHS compliance status as indicated in official documentation. Check manufacturer lifecycle status for obsolescence warnings. Ensure interface compatibility with TTL-level inputs characteristic of the HCT series. Validate thermal requirements against the specified -40 °C to +125 °C operating range.

Selection Notes

Select this component when an octal storage element with TTL-compatible inputs is required. The HCT series ensures compatibility with standard TTL logic levels while offering CMOS noise immunity. Consider the DIP-20 package for prototyping or through-hole PCB designs. Evaluate the 16 ns propagation delay against system timing constraints. Verify that the 4 mA output drive current meets load requirements.

Part Context

This part belongs to the NXP Nexperia 74HCT series of high-speed CMOS logic devices. The 74HCT7273 specifically denotes an octal D flip-flop with master reset. It is designed for general-purpose digital logic applications requiring parallel data storage. The device complements other 74HCT logic families such as gates, counters, and multiplexers.

Replacement Considerations

The 74HCT7273D,118 serves as a surface-mount alternative using the SOT-163 package. Both variants share identical logical functionality and electrical specifications. Selection depends on the required mounting technology and PCB layout constraints.
