MC74LVX50DR2G

Overview

The MC74LVX50DR2G is a hex buffer fabricated with advanced high-speed silicon gate CMOS technology. It operates within a supply voltage range of 2.0 V to 3.6 V and features inputs that tolerate voltages up to 6.5 V, enabling interface between 5.0 V and 3.0 V systems. The device provides balanced propagation delays and includes power-down protection on inputs. It is housed in a 14-lead SOIC package (D suffix) and contains six non-inverting buffers.

Feature Summary

• High-speed performance with typical propagation delay of 4.1 ns at 3.3 V
• Low power dissipation with maximum quiescent current of 2 µA
• High noise immunity with dynamic input thresholds defined as percentages of VCC
• Power-down protection provided on all inputs

Applications

• Interface between 5.0 V and 3.0 V logic systems
• Memory data bus driving applications
• Clock distribution circuits requiring balanced delays

Procurement Notes

Verify the specific ordering suffix 'DR2G' corresponds to the SOIC-14 package and tape & reel shipping configuration. Confirm RoHS compliance and lead-free status via the manufacturer's material declaration. Ensure the application environment remains within the recommended operating temperature range of -40°C to +85°C.

Selection Notes

Select this component when a hex buffer is required for low-voltage digital logic interfacing. The wide input voltage tolerance allows direct connection to higher voltage sources without level shifting components. Consider the package thermal characteristics and pinout compatibility during PCB layout design.

Part Context

This part belongs to the MC74LVX series of advanced high-speed CMOS logic devices manufactured by onsemi. The LVX series is designed for low-voltage applications, offering performance comparable to standard CMOS while consuming significantly less power. The hex buffer function provides signal isolation and drive capability.
