Other Parts Discussed in Thread: SN74HCT240

Tool/software:

Hello team 

i am working on IBIS model of SN74HCT240 in this model ground and power clamp tables are not provided within limits according to IBIS specification 

Power clamp should extend at least  from -VCC to 0(When On die termination used recommended to extend from -vcc to 2vcc)
Ground clamp data must cover -VCC to VCC(When on die termination used  recommended to extend from -VCC to 2VCC)

But this provided IBIS model for SN74HCT240  extend upto -2 to 5V which is incorrect.

pull up pull down tables also have  incorrect range

please send us the updated model
