From the project

Arduino Giga R1 WiFi Shield with SN74LVC8T245PW driven level shifters for Z80 RetroShield interfacing

This is a redesigned shield/daughter board for the Arduino Giga R1 WiFi that replaces the original TXB0108PW auto-sensing bidirectional level translators with SN74LVC8T245PW driven (direction-controlled) level shifters.

The board provides 72 channels of 3.3V-to-5V level shifting across 9 ICs, mapping the Giga's 3.3V GPIO signals to 5V-compatible headers suitable for interfacing with retro hardware such as the Z80 CPU via a RetroShield.
