Engineering Selection Recommendations

Direct Parametric Equivalents (Recommended for Pin-Compatible Replacement):

SN74HC4852QDRQ1 and 74HC4852D-Q100,118 are parametric equivalents with identical electrical specifications to the SN74HC4852DR. Both maintain 195Ohm on-state resistance, 3Ohm channel-to-channel matching, and identical switching times. SN74HC4852QDRQ1 includes AEC-Q100 automotive qualification. 74HC4852D-Q100,118 also carries AEC-Q100 qualification and is manufactured by Nexperia USA Inc. with active product status. Both are housed in 16-SOIC packages compatible with existing PCB layouts.

Active Product Status Alternative:

74HC4852D,118 (Nexperia USA Inc.) is an active product offering identical electrical performance with 16-SOIC packaging. This part provides long-term availability compared to the Last Time Buy status of the original SN74HC4852DR.
