When you go beyond the recommended operating conditions, the electrical characteristics are not longer guaranteed.
For a 5 V supply, use a 5 V device like the SN74AHC245 or SN74LV245A.
3.3 V signals do not work with normal 5 V CMOS inputs. For those,…
Part Number: SN74ALVC245 Other Parts Discussed in Thread: SN74LVC245A , SN74LV245A Hi,
We are using your IC : SN74ALVC245PWR for our control line isolation. When the VCC line and DIR line of the IC is not powered ON and the A1 (pin 2) is fed with +3.3V…
Part Number: SN74ALS245A Other Parts Discussed in Thread: STRIKE , SN74LV245A , Hi team,
When applying SN74ALS245ANSR in buffer, sometimes there would occur output all high level issue and such issue goes with the IC during ABA swap test. See below schematic…
Hi Dan, Thx!
By the way, the schemtic shows two SN74LV245A are used between the DSP output and the DAC input.
Is this just to amplify DSP's output current? I tend to use FPGA to drive input signals to DAC900, and SN74LV245 is unnecessary in this circumstance…
