74HCT273PW,112

Overview

The Nexperia 74HCT273PW,112 is an octal D-type flip-flop belonging to the HCT logic family. It features eight positive-edge triggered D-type flip-flops with a common clock and master reset input. The device operates within a supply voltage range of 4.5 V to 5.5 V. It utilizes a TSSOP-20 surface-mount package. The component supports single-ended inputs and outputs with non-inverting polarity. It is specified for operation across a temperature range of -40 °C to +125 °C.

Feature Summary

• Octal configuration providing eight independent positive-edge triggered D-type flip-flops
• Master reset function forces all outputs low independently of clock and data inputs
• Compatible with TTL input levels while maintaining CMOS output performance
• High noise immunity and latch-up protection exceeding 100 mA per JESD 78 standards

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations in digital systems
• Memory address latching applications
• General-purpose storage elements in microprocessor interfaces

Procurement Notes

Verify the specific suffix '112' against official Nexperia documentation to confirm tape-and-reel packaging specifications. Ensure the ordering code matches the required TSSOP-20 variant. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring eight-bit parallel data storage with synchronous control. The HCT series ensures compatibility with standard TTL logic levels, simplifying interface design with legacy or mixed-voltage components. Consider the TSSOP-20 package for space-constrained PCB layouts. Verify that the operating voltage remains within the 4.5 V to 5.5 V range to ensure reliable switching characteristics and timing performance.

Part Context

This part belongs to the widely adopted 74HCT logic family, known for bridging CMOS technology with TTL compatibility. The 74HCT273 variant specifically provides octal storage capabilities.
