Additional Details

The PI74FCT162245TAA operates from a 5V power supply. Its TTL-compatible inputs allow for easy interfacing with a wide range of digital systems. The device features an output enable (OE) input that, when asserted low, enables the outputs, allowing data to pass through the transceiver. When OE is asserted high, the outputs are disabled, effectively isolating the bus. A direction control (DIR) input determines the direction of data flow. When DIR is low, data flows from A to B; when DIR is high, data flows from B to A. The low ground bounce characteristic minimizes noise generation during switching, contributing to the overall signal integrity of the system. The device is typically available in surface-mount packages like TSSOP (Thin Shrink Small Outline Package) and SSOP (Shrink Small Outline Package), making it suitable for high-density board designs. It adheres to industry-standard specifications for 16-bit transceivers.
