LVTH646

Note 2: Absolute Maximum continuous ratings are those values beyond which damage to the device may occur. Exposure to these conditions or conditions beyond those indicated may adversely affect device reliability. Functional operation under absolute maximum rated conditions is not implied. Note 3: I_O Absolute Maximum Rating must be observed.

The LVTH646 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 clock pin (CPAB or CPBA). (See Functional Description)

The LVTH646 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.

The bus transceivers are designed for low-voltage (3.3V) V_CC applications, but with the capability to provide a TTL interface to a 5V environment. The LVTH646 is fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining low power dissipation.
