8 / 26 page SN74CBT3383, SN54CBT3383 SCDS003P – NOVEMBER 1992 – REVISED DECEMBER 2015 www.ti.com 8.3 Feature Description 8.3.1 Bidirectional Data Flow With Near-Zero Propagation Delay The SN74CBT3383 features a low propagation delay or tpd that works great for multiple rail information transfer from 1A1to 1B1 and 1A2 to 1B2 for example. However, the SNX4CBT3383 also features BUS exchange functionality, which allows for bidirectional data transfers from the inputs and outputs connected on the B side. By enabling the BX pin, the outputs are now crossed, or exchanged, and data can now flow from 1A1 to 1B2 and 1A2 to 1B1 with little to no propagation delay. This can be used to enable byte swapping of buses within a system or to create a 5-wide, 2-to-1 multiplexer. 8.4 Device Functional Modes Table 1 lists the functional modes of the SNx4CBT3383.
