3.3 V to 5 V bidirectional Level Shifter – LVTLS Module (3DLT164245VS1645)

The 3DLT164245VS1645 is a rad-hard advanced highspeed CMOS, Schmitt trigger 32-bit (Dual 16-bit) bidirectional multi-purpose transceiver with 3-state outputs and cold sparing. Designed for use as an interface between a 5 V bus and a 3.3 V bus in mixed 5 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 nput. The A port interfaces with the 3.3 V bus but can also operate at 2.3 V. The B port operates with the 5 V bus.
