DESCRIPTION
The 74LVT16245B is a high-performance BiCMOS product
designed for V
CC
operation at 3.3V .
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.
