DESCRIPTION
The 74ALVT16646 is a high-performance BiCMOS product
designed for VCC operation at 2.5V or 3.3V with I/O compatibility up
to 5V.
This device is a 16-bit transceiver featuring non-inverting 3-State
bus compatible outputs in both send and receive directions. The
control function implementation minimizes external timing
requirements. The device features an Output Enable (OE) input for
easy cascading and a Direction (DIR) input for direction control.
Data on the A or B bus is clocked into the registers on the Low to
High transition of the appropriate clock (CPAB or CPBA). The
select-control (SAB and SBA) inputs can multiplex stored and
real-time (transparent mode data).
