DIODES Incorporated Logic - Buffers, Drivers, Receivers, Transceivers 74LVCH244AT20-13

The 74LVCH244AT20-13 is an octal buffer/line driver featuring bus hold and three-state outputs. It operates within a supply voltage range of 1.65V to 3.6V and is capable of sinking or sourcing up to 24mA at 3V. The device supports mixed voltage applications, as its inputs are tolerant to 5.5V, allowing for compatibility with both 3.3V and 5V systems. The buffer includes IOFF circuitry for partial power-down operation, preventing backflow current when powered down. It also features bus hold circuitry that maintains the state of unused inputs without the need for external resistors. The device is designed with Schmitt trigger action on all inputs, ensuring clean transitions and reducing noise susceptibility. The 74LVCH244AT20-13 is suitable for various applications, including PCs, networking peripherals, and consumer electronics. It is fully RoHS compliant and offers robust ESD protection, exceeding 2000V for the human body model. The package is a TSSOP-20, making it suitable for space-constrained designs.
