MC74LVX50DR2

Overview

The MC74LVX50DR2G is a hex buffer fabricated with advanced high-speed CMOS technology. It operates within a supply voltage range of 2.0 V to 3.6 V. The device features inputs that tolerate voltages up to 6.5 V, enabling interface between 5.0 V and 3.0 V systems. Typical propagation delay is 4.1 ns at VCC = 3.3 V. Quiescent supply current is maximized at 2 µA at 25°C. Output noise immunity is defined by VNIH and VNIL at 28% VCC. Maximum dynamic VOLP is 0.5 V.

Procurement Notes

Verify the ordering suffix DR2G corresponds to the SOIC-14 package with tape and reel shipping configuration. Confirm RoHS compliance and lead-free status via the marking diagram or official distributor documentation. Ensure the part number matches the specific device code LVX50. Check datasheet revision date for latest electrical characteristics.

Selection Notes

Select this component when hex buffering is required with 3.3 V operation. Consider input voltage tolerance if interfacing with 5 V sources. Evaluate propagation delay requirements against the typical 4.1 ns specification. Verify operating temperature range meets application needs from -40°C to 85°C. Assess power dissipation constraints relative to quiescent current specifications.
