and 200V per Machine Model
DESCRIPTION
The 74LVT16244B is a high-performance BiCMOS product
designed for V
CC
operation at 3.3V .
This device is a 16-bit buffer and line driver featuring non-inverting
3-State bus outputs. The device can be used as four 4-bit buffers,
two 8-bit buffers, or one 16-bit buffer.
