Overview
The MC74LCX16244DTG is a high-performance, non-inverting 16-bit buffer produced by onsemi. This device operates from a supply voltage range of 2.3 to 3.6 volts and is designed for low-voltage CMOS applications. It features 5 V-tolerant inputs and outputs, making it compatible with 5.0 V TTL logic. The buffer is nibble controlled, with each nibble having separate Output Enable inputs that can be tied together for full 16-bit operation. This component is suitable for memory address driving and various TTL level bus-oriented applications.
