摘要：
The MUX64 ASIC is a 64 -to -1 analog multiplexer to accommodate 64 inputs, with one addressed to output for ADC readout. It is developed for monitoring of the Low -Gain Avalanche Detectors (LGAD) detector modules in the High Granularity Timing Detector (HGTD) of the ATLAS Phase -II upgrade. The MUX64 chips will be used in the radiation field of high -luminosity pp collisions at LHC to an integrated luminosity of 4000 fb-1. This work presents the radiation tolerance study for the MUX64 being tested with 80 MeV protons and X-ray exposures for damages caused by Non -Ionizing Energy Loss (NIEL) and Total Ionizing Dose (TID), respectively. The irradiated samples demonstrated tolerance to the NIEL to a fluence of 3.21x1015 (Si, 1 MeV) neq/cm2, and the TID of 7.46x105 Gy (Si).
