The SN74AUP1T34 chip for Antminer S19 series, S21 T21 series, L9 hash boards is a voltage level shifter that uses two independent configurable power rails. The A port is used to trace VCCA. VCCA accepts supply voltages from 0.8 V to 3.6 V. The B port is used to trace VCCB. VCCB accepts supply voltages from 0.8 V to 3.6 V. The SN74AUP1T34 is also fully suitable for partial power down applications using loff. The loff circuit disables the output, preventing damaging current flow back through the device in the event of a power outage.
The SN74AUP1T34 chip is compatible with Antminer S21 IMM, S21pro, S21+, S21xp, S21, T21, S21 Hydro, L9, S19+, S19XP Hydro, S19XP+ Hydro, S19jpro, S19kpro, S19 Hydro, S19pro Hydro, K7, L7, KS5, KS5PRO, S19pro, KA3, KS3, S19XP, Iceriver KS3M, LS3L, KS5L, and other hash boards.
SN74AUP1T34DCKR with silkscreen U2E is a single-channel voltage conversion buffer for the hash board, responsible for signal level conversion and transmission. Chip failure will cause distortion and intermittent connection of the corresponding communication signal, leading to abnormal computing power identification, computing power fluctuations, the hash board being unable to be recognized by the control board, and no hash rate output. In severe cases, abnormal signal backflow will interfere with surrounding lines, causing communication failures in adjacent channels.
Wide supply voltage range: 0.8 to 3.6V
Schmitt trigger input with high noise immunity
