Part Number: SN74AHC595 Other Parts Discussed in Thread: SN74AHCT595 Hi,
There are two types of devices SN74AHC595 and SN74AHCT595.
Can anyone explain the difference of these two devices?
I'm reviewing datasheets, and cannot find anything until now.…
There are several alternate parts (SN74AHC595, SN74AHCT595, SN74HCS595, SN74HC595, SN74HCT595, CD74HC595), but all of them have outputs with lower drive strength.
Greetings,
Switching parametric table is based on 15pF capacitive loading and 50-ohm transmission line impedance. As long as we are within limit we should be fine. Was able to find a TI serial shift register that can meet this requirement(10pF maximum…
A 1k pull-up won't drive 5mA -- it will only create that much current if it has dropped 5V across it, so that means the output voltage is 0V.
The get any reasonable drive strength, generally you're going to need a pull-up of about 50 ohms or less…
Hi Kiran,
What is the supply voltage being used and the external loading on the ADG5412? With 3 Vcc, the Vih 2V should be fine. But with 5V Vcc, the Vih is not sufficient. You could consider using the SN74AHCT595 which has 2V Vih for 5Vcc.
The current consumpion is mostly determined by leakage currents through the ESD protection diodes. It's typically a few nanoamperes at 25 °C, and increases with temperature.
The SN74HC164 does not have an I²C input. You are controlling it with…
Hi chuchen ,
There is SN74AHCT595 to consider , but couldn't find any SN74HCT594.
What is the application need you have for the higher drive current ?
I would suggest to drive a buffer like SN74LVC244A which supports higher current drive. The AMR…
