The VCCA pin accepts a 5V supply level. The “A” port is a dedicated 5V port. The VCCB pin accepts a 3V-to-5V supply level. The “B” port is configured to track the VCCB supply level respectively. A 5V level on the VCC pin will configure the I/O pins at a 5V level and a 3V VCC will configure the I/O pins at a 3V level. This device will allow the VCCB voltage source pin and I/O pins on the “B” port to float when OE is HIGH. This feature is necessary to buffer data to and from a socket that permits live insertion and removal during normal operation. Features Bidirectional interface between 5V and 3V-to-5V buses Control inputs compatible with TTL level Outputs source/sink up to 24 mA Available in Cerpack and CDIP packages Implements patented EMI reduction circuitry Flexible VCCB operating range Allows B port and VCCB to float simultaneously when OE is HIGH n Functionally compatible with the 54 series 245 n Standard Microcircuit Drawing (SMD) 5962-9862001 n n n n n n n Ordering Code Order Number 54LVXC4245W-QML 54LVXC4245J-QML Package Number W24C J24F 24-Lead Ceramic Flatpack 24-Lead Ceramic Dual-in-li...
