Additional Details

The PI74LPT16543AC operates at 3.3V and integrates separate D-type registers for both A and B ports, enabling independent data storage. The tri-state outputs facilitate bus isolation by allowing the device to be disconnected from the bus when not actively transmitting. This feature is crucial in multi-drop bus configurations. The inputs are designed to be TTL-compatible, making integration with older systems easier. Commonly available in TSSOP (Thin Shrink Small Outline Package), it allows for high-density board layouts. The design minimizes ground bounce and noise, ensuring a cleaner signal transmission. The typical operating temperature range is -40°C to +85°C, making it suitable for a variety of industrial applications.
