Additional Details
The PI74FCT2244TQ operates with a supply voltage typically around 5V. It provides significant current sourcing and sinking capabilities, allowing it to drive heavily loaded lines. The three-state outputs enable multiple devices to share a common bus, allowing for controlled data transfer. The propagation delay is a key performance parameter, and the FCT family is designed to minimize this delay, contributing to the overall speed of the system. The low ground bounce feature minimizes noise generation during switching, improving signal integrity. The device is typically packaged in a TSSOP (Thin Shrink Small Outline Package) or similar small form factor, making it suitable for high-density board layouts. The operating temperature range is usually specified between -40°C to +85°C. The input pins are designed to handle standard TTL logic levels, and the output pins can drive both TTL and CMOS loads. This makes the PI74FCT2244TQ a versatile component for a wide range of digital applications.
