Overview
The MC74LCX541DWG is a low-voltage CMOS octal buffer with flow-through pinout and 3-state non-inverting outputs. It operates from a 1.65 V to 5.5 V supply, featuring 5 V tolerant inputs and outputs for TTL level bus applications. The device provides balanced output sink and source capability of 24 mA at 3 V. Propagation delay ranges from 5.9 ns to 10.3 ns depending on voltage. It supports live insertion, guarantees high impedance when VCC = 0 V, and includes ESD protection exceeding 2000 V via human body model.
Feature Summary
- Flow-through architecture with inputs and outputs on opposite sides of the package
- 5 V tolerant inputs and outputs enabling safe interface with 5 V TTL logic
- Supports live insertion and withdrawal with IOFF specification for power-down high impedance
Applications
- Memory address driving
- TTL level bus oriented transceiver applications
- Low-voltage buffer interfaces
Procurement Notes
Verify the SOIC-20 package designation (DW suffix) matches the required footprint. Confirm RoHS compliance and Pb-free status as standard for this part number. Check moisture sensitivity level requirements during storage and handling. Ensure ordering information aligns with rail packaging specifications provided in the datasheet.
Selection Notes
Select this component for designs requiring low-voltage operation down to 1.65 V while maintaining compatibility with 5 V systems. The flow-through pinout facilitates easier PCB layout compared to traditional buffers. Consider the 24 mA drive capability for moderate load requirements and the near-zero static supply current for power-sensitive applications.
Part Context
This device belongs to the MC74LCX series of low-voltage CMOS logic components manufactured by onsemi. It functions similarly to the MC74LCX244 but utilizes a flow-through architecture. The series is designed for high-performance applications requiring low power consumption and wide voltage tolerance.
Replacement Considerations
MC74LCX244DWG: Similar function but inverted outputs and different pinout. MC74ACT541DWG: Higher voltage range (4.5V-5.5V), not suitable for low-voltage operation.
