SN74LVC1T45DCKR TA

SN74LVC1T45DCKR single-bit dual-supply bus transceiver with configurable voltage translation and 3-state outputs uses two separate configurable power-supply rails. The A port is designed to track V_cca. Vcca accepts any supply voltage from 1.65V to 5.5V. The B port is designed to track V_ccb. V_ccb accepts any supply voltage from 1.65V to 5.5V.

The SN74LVC1T45DCKR chip marked by TA silkscreen can be used in the hash board of Antminer and Whatsminer.

This allows for universal low-voltage bidirectional translation between any of the 1.8V, 2.5V, 3.3V, and 5V voltage nodes. The SN74LVC1T45 is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction control (DIR) input. The input circuitry is always active on both A and B ports and must have a logic HIGH or LOW level applied to prevent excess I_cc and I_ccz.
