Additional Details

The PI74LPT16543CAX operates on a 3.3V power supply. It incorporates separate D-type registers for both A and B ports, facilitating independent data storage. The tri-state outputs enable bus isolation by allowing the device to disconnect from the bus when not actively transmitting, a vital feature for multi-drop bus configurations to prevent contention. TTL-compatible inputs allow straightforward integration with existing and legacy systems. It is generally available in TSSOP (Thin Shrink Small Outline Package), suitable for high-density board layouts. The design is optimized to minimize ground bounce and noise, thereby ensuring clean signal transmission. The typical operating temperature range is -40°C to +85°C, making it appropriate for industrial applications.
