The 74ABT16543 is a 16-bit dual enable (3-State) latched transceiver from Philips Semiconductors. It has two sets of D-type latches for temporary storage of data flowing in either direction. The device supports hot insertion/extraction, power-up 3-State, and power-up reset. Multiple VCC and GND pins minimize switching noise. Back-to-back registers are used for storage. Separate controls for data flow in each direction are provided. The 74ABTH16543 incorporates bus-hold data inputs that eliminate the need for external pull-up resistors to hold unused inputs.
The document provides a product specification for the Philips 74ABT16543 and 74ABTH16543 integrated circuits. These are high-performance BiCMOS devices that combine low static and dynamic power dissipation with high speed and high output drive capabilities.
