Other Parts Discussed in Thread: SN74LVC1T45

HI,

Can you please tell me the exact value of Vol(max) when VCCB=1.8V, because i am interfacing this SN74LVC1T45 with other device which is Vil(max)is 0.36V. so SN74LVC1T45's Vol(max) should be less then 0.36V(other device Vil(max)).

also please let us know below,

SN74AVC2T245RSWR for this part, what is the Voh(min), if supply voltage VCCB=1.8V

SN74LVC1T45DRLR for this part, what is the Vol (max), is supply voltage VCCB=2.5V

regards,

CMOS outputs have a constant resistance, so V_OL depends on the output current, which you have not told us.

When connected to a high-impedance CMOS input, the current is almost zero, so V_OL will be almost 0 V.

See [FAQ] How do I determine the output voltage (VOH, VOL) or output current (IOH, IOL) of a CMOS logic device?
