The 74LVTH16646 contains sixteen non-inverting bidirec-tional registered bus transceivers providing multiplexed transmission of data directly from the input bus or from the internal storage registers. Each byte has separate control inputs which can be shorted together for full 16-bit opera- tion. The DIR inputs determine the direction of data flow through the device. The CPAB and CPBA inputs load data into the registers on the LOW-to-HIGH transition (see Functional Description).

The 74LVTH16646 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.

These transceivers are designed for low-voltage (3.3V)V  applications, but with the capability to provide a TTLCC interface to a 5V environment. The 74LVTH16646 is fabri- cated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining low power dissipation.
