The SN74ABT16640DGGR is a 16-bit bus transceiver manufactured by Texas Instruments. It is a dual-channel device with two independent bidirectional bus interfaces, which allow it to convert data from one interface to the other. The transceiver features inputs and outputs designed for use with LVTTL, LVCMOS, SSTL, HSTL, and other logic standards. It offers low skew times between the output drivers, allowing for good signal integrity. The transceiver also features hot-swap protection on the outputs, limiting potential bus contention during power up and power down. Additionally, the SN74ABT16640DGGR has an enable control that allows the user to disable the outputs when needed.
