EMIF03-SIM02M8 VDD, GND pad connections
Hi, I have two pin connection questions, related to EMIF03-SIM02M8: 1) Are VDD pins 1 & 8 connected internal to the chip or should be connected together externally?2) Pin 9, GND does it have to be connected to system ground, or that's optional?Any la...
STMicro TSX339IQ4 Vcm, as drop-in for TI LM339LVRTE?
I'm looking at this ST Micro part ST MICROELECTRONICS TSX339IQ4 --- power from 2.7V to 16V. But Vicm limitation of Vcc - 2V. At 3.3V-2V = 1.3V. But need Vcm at 2.5V., so 2.5V + 2V = 4.5V, so likely Vcc = 5V.as an alternative source...
