74LVT273PW,112

Overview

The 74LVT273PW,112 is an octal D-type flip-flop manufactured by NXP USA Inc. It features positive-edge triggering and non-inverting outputs with three-state capability. The device operates within a supply voltage range of 1V to 5.5V. It utilizes a 20-TSSOP package (0.173 inch width). Key electrical parameters include a maximum propagation delay of 17ns at 5V with 50pF load, output currents of 16mA for both high and low states, and a static current of 160µA. The clock frequency rating is 70MHz.

Feature Summary

• Octal D-type configuration with positive-edge triggering mechanism
• Three-state non-inverting outputs for bus-oriented designs
• Wide operating voltage range supporting 1V to 5.5V systems

Applications

• Parallel data storage in digital logic circuits
• Bus-oriented memory register implementations
• Clocked data latching applications

Procurement Notes

This component is officially marked as obsolete and no longer manufactured by the producer. Procurement must rely on existing distributor stock or secondary market sources. Verify part authenticity carefully due to potential availability of surplus or refurbished units. Confirm package integrity and pin compatibility before integration into new designs.

Selection Notes

Engineers should evaluate alternative active components from the same logic family or compatible manufacturers. Consider voltage levels, package dimensions, and performance metrics when selecting replacements. Ensure that substitute devices meet the required timing specifications and output drive capabilities for the target application environment.

Part Context

The 74LVT273 belongs to the LVT logic series, designed for low-voltage CMOS applications. This specific variant integrates eight D-type flip-flops with clear functionality into a single integrated circuit. The PW suffix indicates the TSSOP surface-mount packaging format used for this particular ordering code.
