Part Details:

74L January 1999 VX16 Revised June 2005 1284 Lo 74LVX161284 Low Voltage IEEE 161284 Translating Transceiver w V General Description Features olt The LVX161284 contains eight bidirectional data buffers s Supports IEEE 1284 Level 1 and Level 2 signaling age and eleven control/status buffers to implement a full standards for bidirectional parallel communications IEEE 1284 compliant interface. The device supports the between personal computers and printing peripherals I IEEE 1284 standard and is intended to be used in an s Translation capability allows outputs on the cable side to E Extended Capabilities Port mode (ECP). The pinout allows interface with 5V signals E for easy connection from the Peripheral (A-side) to the E s All inputs have hysteresis to provide noise margin Host (cable side). 161284 s B and Y output resistance optimized to drive external Outputs on the cable side can be configured to be either cable open drain or high drive (r 14 mA) and are connected to aseparate power supply pin (V s B and Y outputs in high impedance mode during power CC-cable) to allow these out- down puts to be driven by a higher supply voltage than the A- T side. The pull-up and pull-down series termination resis- s Inputs and outputs on cable side have internal pull-up r resistors anslat tance of these outputs on the cable side is optimized todrive an external cable. In addition, all inputs (except HLH) s Flow-through pin configuration allows easy interface and outputs on the cable side contain internal pull-up resis- between the "Peripheral and Host" tors connected to the VCC-cable supply to provide proper s Replaces the function of two (2) 74ACT1284 devices in termination and pull-ups for open drain mode. g T Outputs on the Peripheral side are standard low-driveCMOS outputs designed to interface with 3V logic. The DIR ranscei input controls data flow on the A1­A8/B1­B8 transceiverpins.
