description
The SN74ALB16244 16-bit buffer and line driver
is designed for high-speed, low-voltage (3.3-V)
V_CC operation. This device is intended to replace
the conventional driver in any speed-critical path.
The small propagation delay is achieved using a
unity-gain amplifier on the input and feedback
resistors from input to output, which allows the
output to track the input with a small offset voltage.
The device can be used as four 4-bit buffers, two
8-bit buffers, or one 16-bit buffer. This device
provides true outputs and symmetrical active-low
output-enable (OE) inputs.
