ON Semiconductor MC74HCT244ADTR2G Octal Buffer/Line Driver

The MC74HCT244ADTR2G is a high-performance, octal buffer and line driver designed to interface with 5V systems. Manufactured by ON Semiconductor, this device is part of the HCT (High-Speed CMOS, TTL compatible) family and offers a robust solution for driving bus lines or buffering memory address registers.

The MC74HCT244ADTR2G features eight non-inverting buffers with 3-state outputs, which makes it ideal for driving heavily loaded bus lines with high capacitance, as it provides both high-speed operation and the ability to drive up to 15 LSTTL loads. With the 3-state control, the device ensures efficient data flow by allowing multiple outputs to connect to a bus without the risk of contention.

The device operates over a wide voltage range from 4.5V to 5.5V, which provides a margin of safety for 5V logic systems and ensures compatibility with a broad range of digital circuits. The inputs are TTL voltage level compatible, which allows for direct interfacing with traditional TTL logic without the need for additional level shifting, making it a versatile choice for mixed-technology systems.

The MC74HCT244ADTR2G also boasts a high noise immunity characteristic of CMOS devices, ensuring stable performance in electrically noisy environments. The package type is TSSOP-20 (Thin Shrink Small Outline Package), which provides a compact footprint while allowing for adequate thermal performance.

Key features of the MC74HCT244ADTR2G include:

• Octal non-inverting buffer with 3-state outputs
