Holtek Semiconductor HT45FH3T
The HT45FH3T I/O lines, PB0/TCK3, PB1/TP3, PB2~PB4, are internally connected to the level shift inputs, A, B, C, D and ENBF , respectively. The PA5/INT0/TCK0/TP2_0 I/O line is not bonded to the external pin and must be appropriately managed to avoid the power consumption due to the unknown input voltage level. The 16 SSOP-A package is for the real IC, the 16 NSOP-A package is for the OCDS EV IC.FEATURES
