MC74LCX541DTR2G

Overview

The MC74LCX541DTR2G 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 latchup performance exceeding 100 mA.

Feature Summary

• Features 5 V tolerant inputs and outputs enabling safe interfacing with 5 V devices.
• Supports live insertion and withdrawal without damage.
• Provides IOFF specification ensuring high impedance state during power-off conditions.

Applications

• Memory address driving
• TTL level bus oriented transceiver applications

Procurement Notes

Verify the specific package suffix (DT) corresponds to the required TSSOP-20 form factor. Confirm RoHS compliance and Pb-Free status as indicated by the G suffix. Ensure the ordering quantity matches the tape and reel specifications provided in the manufacturer's documentation.

Selection Notes

Select this component for designs requiring low static power consumption and high noise immunity. The flow-through architecture simplifies PCB layout compared to standard octal buffers. Verify that the operating voltage range aligns with the system's power rails and that the 24 mA drive current meets load requirements.

FAQ

What is the maximum input voltage allowed?

The DC input voltage can withstand up to 6.5 V, allowing compatibility with 5 V logic systems.

How does the device handle power-down conditions?

The IOFF specification guarantees that outputs enter a high impedance state when VCC is 0 V, preventing back-feeding into the power rail.
