description
The SN74ALB16245 is a 16-bit transceiver
designed for high-speed, low-voltage (3.3-V) V_CC
operation. This device is intended to replace the
conventional transceiver 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.
This device can be used as two 8-bit transceivers
or one 16-bit transceiver. It allows data
transmission from the A bus to the B bus or from
the B bus to the A bus, depending on the logic level
at the direction-control (DIR) input. The
output-enable (OE) input can be used to disable
the device so that the buses are effectively
isolated.
