General Description

The LVTH32952 is a 32-bit registered transceiver. Four 8-bit back to back registers store data flowing in both directions between two bidirectional buses. Separate clock, clock enable, and output enable signals are provided for each register.

The LVTH32952 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.
