1.8 V to 3.3 V bidirectional Level Shifter – LVTLS Module (3DLT163245US1696)

The 3DLT163245US1696 is a rad-hard advanced highspeed CMOS, Schmitt trigger 32-bit (Dual 16-bit) idirectional multi-purpose transceiver with 3-state outputs, cold sparing and bus hold capability. Designed to be used as an interface between a 3.3 V bus and a 1.8 V bus in mixed 1.8 V/3.3 V supply systems, it achieves high-speed operation while maintaining the CMOS low-power dissipation. All pins have cold spare buffers to change them to high impedance when Vcc is tied to ground.

This module is intended for two-way asynchronous communication between the data buses. The direction of the data transmission is determined by the DIR input.
