Misunderstood SN74AVCB324245 electrical characteristics.

Other Parts Discussed in Thread: SN74AVCB164245

Hi,

In the Description/Ordering Information section of the SN74AVCB324245 's  datasheet it is specified that "The SN74AVCB324245 is designed so that the control pins (1DIR, 2DIR, 1OE and 2OE) are supplied by Vccb", but there are no comments about the other control pins: 3DIR, 4DIR, 3OE and 4OE. Are they also supplied by Vccb? 

C.J.

  • Hi CJ, All control pins are referenced to VCCB. The VIH and VIL specs in Recommended Operating Conditions refer to all "Control inputs" as "Referenced to VCCB." This includes 3DIR, 4DIR, etc.

    I think the lack of mentioning the 3 and 4 pins in the Description section is due to a copy & paste error/oversight from the SN74AVCB164245 datasheet when the team created a 32-bit version.
