ON Semiconductor MC74LCX244DTG Octal Buffer/Line Driver

The MC74LCX244DTG from ON Semiconductor is a high-performance, octal buffer and line driver designed to interface with 3.3V and 5V systems. This integrated circuit features eight non-inverting buffers with 3-state outputs, making it an ideal choice for driving bus lines or buffer memory address registers. Its low-voltage operation and power-down high impedance inputs and outputs make it particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working as a transient suppressor for data transmission lines in a wide range of applications.

Constructed with advanced silicon gate CMOS technology, the MC74LCX244DTG provides a robust and power-efficient solution for modern electronic systems. The device has a 5V tolerant input, which allows for direct interfacing with 5V TTL logic without the need for additional level shifters. Its high impedance during power down ensures that the outputs do not load the bus when the device is powered off.

The MC74LCX244DTG operates over a broad voltage range of 2.0V to 3.6V and features a minimal propagation delay, making it an excellent choice for high-speed applications. The device also offers a reduced noise version of the popular LCX family by ensuring a lower ground bounce noise and better output signal quality.

Key features of the MC74LCX244DTG include:

• Support for mixed 3.3V and 5V voltage supplies
• High impedance when V<sub>CC is at 0V
• Non-inverting buffers with 3-state outputs
• 5V tolerant inputs
• Low quiescent current consumption
• ±24mA output drive capability at 3.0V
• Industrial operating temperature range from -40°C to +85°C

The MC74LCX244DTG comes in a TSSOP-20 package, offering a compact footprint for space-constrained applications. It is also lead-free and RoHS compliant, adhering to environmental regulations and ensuring a sustainable product for electronic markets. Whether you are designing for consumer electronics, computing devices, or communication infrastructure, the ON Semiconductor MC74LCX244DTG provides a reliable and efficient solution for your buffering and driving needs.
