74LVTH16543MTD

The LVT16543 and LVTH16543 16-bit transceivers contain two sets of D-type latches for temporary storage of data flowing in either direction. Separate Latch Enable and Output Enable inputs are provided for each register to permit independent control of inputting and outputting in either direction of data flow. Each byte has separate control inputs, which can be shorted together for full 16-bit operation.
The LVTH16543 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) VCC applications, but with the capability to provide a TTL interface to a 5V environment.
The LVT16543 and LVTH16543 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining low power dissipation.
