Overview
The MC74LCX541DTR2G, produced by onsemi, is a high-performance, non-inverting octal buffer designed to operate within a voltage range of 2.3 to 3.6V. This device is similar in function to the MC74LCX244 but features a flow-through architecture. It is particularly suited for memory address driving and all TTL level bus-oriented transceiver applications. The MC74LCX541DTR2G has high impedance TTL-compatible inputs, which reduce current loading on input drivers, and TTL-compatible outputs that enhance switching noise performance. Additionally, it supports live insertion and withdrawal and has a 5V tolerant interface capability, allowing safe operation with 5V TTL logic devices.
