Part Number: SN74LVC4245A Other Parts Discussed in Thread: SN74AXC8T245 I am trying to find a bus transceiver to connect the STM32 ARM processor which operate at 3.3V to some DACs and ADCs that operate at 5V, asynchronous operation SPI bus.
I saw the…
Part Number: SN74LVC4245A Other Parts Discussed in Thread: SN74LXC8T245 , TMUX1574 , SN74LV4066A Hello, I need to interface my 3.3V MCU IO ports to a connector that will be connected to either a 5V or a 3.3V system. I learned about the SN74LVC4245A, an 8…
Part Number: SN74LVC4245A Other Parts Discussed in Thread: SN74LXC8T245 Hi there,
SN74LVC4245A datasheet's recommendation for a correct Power up is to connect /OE pin to VCCA so it ramps with the Voltage.
At this stage, due to design constraints, we…
Part Number: SN74LVC4245A Hi Expert,
My customer found the issue of leakage to VccB.
They supplied to the following power to VccA and VccB. (just supply power)
At that time, VccB voltage increased to around 3.9V.
VccA=5V
VccB=3.3V (LDO 5V to 3.3V)
…
Part Number: SN74LVC4245A Hello,
The SN74LVC4245A datasheet says the control circuit for DIR and OE is powered by VCCA (5V). The Vih-min of DIR and OE is 2V. In theory this could be driven from a device powered by 3.3V. In our application the DIR is to…
