74LVXZ161284 Low Voltage IEEE 161284 Translating Transceiver with Power-Up Protection May 2002 Revised May 2002 74LVXZ161284 Low Voltage IEEE 161284 Translating Transceiver with Power-Up Protection General Description The LVXZ161284 contains eight bidirectional data buffers and eleven control/status buffers to implement a full IEEE 1284 compliant interface. The device supports the IEEE 1284 standard and is intended to be used in an Extended Capabilities Port mode (ECP). The pinout allows for easy connection from the Peripheral (A-side) to the Host (cable side). Outputs on the cable side can be configured to be either open drain or high drive (± 14 mA) and are connected to a separate power supply pin (VCC-Cable) that allows these outputs to be driven by a higher supply voltage than the A-side. The pull-up and pull-down series termination resistance of these outputs on the cable side is optimized to drive an external cable. In addition, the C inputs and the B and Y outputs on the cab...
