Hi all,

 

I have several questions datasheet @ HMC394LP4E.

 

1.

page 6, Absolute Maximum Ratings

What does it mean, "VLogic -1.6 to -1.2 Vcc" ? Negative voltage ?

CMOS compatible input level is,

Hi : 0.7*Vcc

Low : 0.2*Vcc

max : Vcc ?

min : -1.6 to -1.2 Vcc ?

 

2.

page 12, CMOS/TTL Input Characteristics

Maximum Input Logic “0” Voltage (VIL MAXIMUM) = 1.1V @ 10 uA.

Minimum Input Logic “1” Voltage (VIH MINIMUM) =  1.8V @ 500 uA

 

But in the graph @ input IV characteristics is,

Maximum Input Logic “0” Voltage (VIL MAXIMUM) = 1.1V @ -0.5 mA.

Minimum Input Logic “1” Voltage (VIH MINIMUM) =  1.8V @ -0.3 mA

 

What is the difference each data ?

 

Best regards,

sss
