SN54ACT244: Is there any short circuit protection at the output

Part Number: SN54ACT244

Dear sir,

we are using this buffer to send a decision logic to the other system situated physically away by 1 meter.

we are worried in case of short circuit situations at output. Whether SN54ACT244 has short circuit protection scheme internal to the device?

if not available with in the device, could you suggest a scheme where output current may not be limited with in +/- 20mA

    There is no internal short circuit protection in the device. 

    The abs max table of the datasheet spec has 50mA output current limit beyond which it can have reliability issues.

    Having an external series limiting resistor is a simple way to limit the current not to exceed beyond the recommended limits.
