Part Number: SN74LVC1T45

Hi Team,

Can u suugest the impedance matching circuit compatible with the SN74LVC1T45. I have two 150R at input and output for dampening.

While measuring the output from custom board using 75ohm BNC to BNC connector i am getting the output as follows:-


The output is bad as frequency is getting increased. So i am suspecting the imepdance mismatching for this.

Can somebody provide any suugestion on this?

Thank you
