Part Number: SN74LVTH244A Other Parts Discussed in Thread: SN74LV244A , SN74HC244 , SN74LVCH244A , SN74ALVCH244 Besides the operating voltage difference and characteristic ambient temperature, are there any other parameters you think are important, that…
According to the datasheet IOH and IOL are 24mA max. In interfacing with an FPGA, what determines the actual value of IOH? For instance, though 24mA is the maximum, what factors determine if it is lower. Can it be 4mA, 8mA, etc?
Using a SN74LCVH244A and have a question pertaining to the input current. Ii on the datasheet states +-5uA max. If the input is either going to be a GND or a pull up to 3.3V, does this imply that the pull up resistor is very large, given that the input…
Hello,
1. Yes both the SN74LVC244APW and the SN74LVC244ADB are different. The SN74LVC244APW comes with a PW packaging while the SN74LVC244ADB comes with DB package type. You can find both these package drawings in the datasheet.
2. I believe the…
Hi Nibin,
My recommendation would be to use the SN74LVC2G125 (dual channel) or the SN74LVC1G125 (single channel). These devices have Ioff protection like the SN74LVCH125A, and also operate up to 5V like the HC125. The reduced channel count is a benefit…

Thanks for your information. I have another question. What is the Bushold Input Over-Drive Current to Change State of SN74LVC244A?
