SN74HC4851-Q1: Switch through current

Part Number: SN74HC4851-Q1

Hi team,

We are looking for the decoder which has 3 control signals and 8 outputs.

We could not find a product that satisfys the required output current which is about 20mA.

So, I'm looking for a multiplexer that can supply current of about 20 mA.

I found several 8:1 multiplexers like SN74HC4851-Q1, but I can not judge to use when the switch current is around 20 mA.

I know that it can only be used less than 25mA, because it is written that the maximum rating of these devices is 25mA in the datasheet.

I want a material to judge how much current it can be used.

For example, it is Ron at 5mA, 10mA, 15mA and 20mA etc.


Please tell me if there are restrictions on switch current.

For our usage, Vdd and Vcom are supposed to be 5V.

Best regards,

Tomoaki Yoshida
