Additional Details

The TC74LCX16244AFT features TTL-compatible inputs, allowing it to interface seamlessly with older 5V TTL logic while operating at 3.3V. This simplifies the design of mixed-voltage systems. The device provides a high output drive capability (±24 mA), ensuring reliable signal transmission across the bus. The low power consumption (ICC = 10 μA max) makes it suitable for portable and battery-powered applications. Its propagation delay is typically around 4.5ns, depending on the supply voltage and load conditions. The device is supplied in a thin shrink small outline package (TSSOP), which is ideal for space-constrained applications. The AFT suffix indicates that the part is supplied in tape and reel packaging, suitable for automated assembly processes.
