Overview
The MC74LCX541MELG 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 direct interface with 5 V TTL logic. The device provides balanced 24 mA output sink and source capability at 3 V. Propagation delay ranges from 5.9 ns to 10.3 ns depending on voltage. It supports live insertion and withdrawal, includes an IOFF specification for high impedance when VCC = 0 V, and offers near-zero static supply current.
Feature Summary
- Flow-through architecture with input and output pins located on opposite sides of the package for simplified PCB layout.
- 5 V tolerant I/O capability allowing safe interfacing between 1.65 V to 5.5 V devices and 5 V logic systems.
- High-impedance state isolation guaranteed by IOFF specification when power is removed.
Applications
- Memory address driving
- TTL level bus oriented transceiver applications
- Clock distribution buffers
Procurement Notes
Verify the specific suffix 'MELG' against official ordering lists to confirm package type (SOIC or TSSOP) and tape/reel specifications. Ensure compliance with RoHS and Pb-Free requirements as stated in the datasheet. Confirm automotive qualification status if applicable, as standard parts differ from -Q suffix variants.
Selection Notes
Select this component for designs requiring bidirectional data buffering with mixed voltage domains. The flow-through pinout is optimal for microprocessor interfaces where trace density is critical. Ensure operating voltage stays within 1.65 V to 5.5 V limits to maintain specified propagation delays and drive strengths.
Part Context
This part belongs to the MC74LCX series of low-voltage CMOS logic devices. It functions similarly to the MC74LCX244 but utilizes a flow-through pin configuration. The series is designed for high-speed, low-power applications in portable and battery-operated equipment.
Replacement Considerations
MC74LCX244: Similar function but lacks flow-through pinout. MC74VHC541: Higher speed but different voltage tolerance characteristics. Verify pin compatibility and electrical parameters before substitution.
