Overview
The MC74LCX541DWR2G is a low-voltage CMOS octal buffer with flow-through pinout, featuring 5 V-tolerant inputs and outputs. It operates from a 1.65 to 5.5 V supply and provides non-inverting 3-state logic. The device supports live insertion and withdrawal, with an IOFF specification guaranteeing high impedance when VCC = 0 V. Output drive capability reaches 24 mA at VCC = 3 V. Propagation delays range from 5.9 ns to 10.3 ns depending on voltage. It is housed in a 20-lead SOIC package.
Feature Summary
- Features 5 V tolerant inputs and outputs for safe interfacing between 5 V devices and lower voltage systems.
- Supports live insertion and withdrawal applications through guaranteed high impedance during power-off conditions.
- Provides balanced output sink and source current capabilities of 24 mA at 3 V operation.
Applications
- Memory address driving
- TTL level bus oriented transceiver applications
Procurement Notes
Verify the complete part number including suffixes such as 'G' for Pb-Free packaging and 'R2' for tape and reel quantity. Confirm the specific package type (SOIC-20) matches your board layout requirements. Ensure compatibility with your system's operating voltage range between 1.65 V and 5.5 V before procurement.
Selection Notes
Select this component when designing systems requiring interface between 5 V TTL logic and lower voltage CMOS circuits. The flow-through architecture facilitates PCB routing. Consider the 24 mA output drive if connecting to moderate capacitive loads. Verify that the 20-lead SOIC package fits within your available footprint constraints.
Part Context
This device belongs to the MC74LCX series of low-voltage CMOS logic components manufactured by onsemi. It shares functional similarities with the MC74LCX244 but utilizes a distinct flow-through pinout configuration. The series is designed for high-performance applications requiring low power dissipation and compatibility with standard logic families.
Replacement Considerations
MC74LCX244: Similar function but different pinout. MC74LVC541: Different voltage tolerance characteristics. Verify pin compatibility and electrical specifications before substituting any alternative part numbers.
