Overview
The MC74LCX541DT is a high-performance, non-inverting octal buffer produced by ON Semiconductor. This device operates within a voltage range of 2.3 to 3.6 V and is designed for low-voltage CMOS applications. It features a flow-through pinout and is similar in function to the MC74LCX244 but with the added benefit of flow-through architecture. The MC74LCX541DT is 5 V tolerant, allowing it to be safely driven from 5 V devices, and it supports live insertion and withdrawal. This buffer is ideal for memory address driving and TTL level bus-oriented transceiver applications.
