Overview
The MC74LCX541DTR2, produced by onsemi, is a high-performance, non-inverting octal buffer designed for low-voltage CMOS applications. This device operates within a supply voltage range of 2.3 to 3.6 V and is compatible with both LVTTL and LVCMOS logic levels. It features a flow-through pinout, similar to the MC74LCX244, but with enhanced functionality. The MC74LCX541DTR2 is notable for its 5 V tolerant inputs and outputs, making it suitable for interfacing with 5 V TTL logic devices. It also supports live insertion and withdrawal, and its high impedance TTL compatible inputs reduce current loading on input drivers.
