74LCX646 Low Voltage Octal Transceiver/Register with 5V Tolerant Inputs and Outputs February 1994 Revised April 1999 74LCX646 Low Voltage Octal Transceiver/Register with 5V Tolerant Inputs and Outputs General Description The LCX646 consists of registered bus transceiver circuits, D-type flip-flops, and control circuitry providing multiplexed transmission of data directly from the input bus or from the internal storage registers. Data on the A or B bus will be loaded into the respective registers on the LOW-to-HIGH transition of the appropriate pin (CPAB or CPBA)(see Functional Description). The LCX646 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of...
