MC74VHC244DWR2G Description

Short technical summary and product information.

The MC74VHC244DWR2G is an advanced high-speed CMOS octal bus buffer from ON Semiconductor, fabricated with silicon gate CMOS technology. This non-inverting, 3-state buffer features two active-low output enables and is designed for applications such as 3-state memory address drivers.

 

With a wide operating voltage range of 2.0V to 5.5V, the MC74VHC244 is suitable for interfacing between different voltage systems. It offers high noise immunity and balanced propagation delays, with a typical tPD of 3.8 ns at 5.0V for the VHC variant. The device is housed in a 20-SOIC surface-mount package.

 

Key electrical characteristics include a low supply current of 4.0 mA maximum at 25°C and output drive capability of 8mA. The inputs tolerate voltages up to 5.5V, allowing interface of 5V systems to 3V systems. The MC74VHC244 also provides power-down protection and latchup performance exceeding 100 mA.

 

This buffer is pin and function compatible with other standard logic families. It is Pb-free and halogen-free, meeting RoHS compliance standards. The operating temperature range is -55°C to 125°C.
