Can a 2N2222 transistor handle PTT switching on the Flex 6500?

I am seeking a solid-state answer to PTT switching and wonder if anyone can tell me if a 2N2222 can handle the current? Tnx es 73 de Arnie W8DU

    Arnie, If your talking about the PTT signals going into the Flex 6500/6700, the answer is yes.. Al, K0VM

    Thanks Al. Yes, I am talking about the PTT line that puts the radio in transmit mode when the line is taken low. I want to control that line with a 2N2222 if it can handle the current (Am not sure what the current requirment is, hence this inquiry). I am not talking about amplifier switching. 73 de Arnie W8DU

    Great transistor, some of them can take an amp of current.

    From the 2N2222 Datasheet: DESCRIPTION The 2N2219A and 2N2222A are silicon Planar Epitaxial NPN transistors in Jedec TO-39 (for 2N2219A) and in Jedec TO-18 (for 2N2222A) metal case. They are designed for high speed switching application at collector current up to 500mA, and feature useful current gain over a wide range of collector current, low leakage currents and low saturation voltage. I assume this is for the TO-18 metal case, but the plastic case version will also cover any switching the 6000 series has except for amplifier switching.
