The SN74LVC16244A device is a 16-bit buffer/driver. This device can be used as four 4-bit, two 8-bit, or one 16-bit buffer. It allows data transmission from the A bus to the Y bus with 4 separate enable pins that control 4 bits each. The output-enable (OE) input can be used to disable sections of the device so that the buses are effectively isolated. The device has 5.5 V tolerant inputs at any valid VCC which allows it to be used in multi-power systems and can be used for down translation.
This device uses CMOS technology and has balanced output drive. Care should be taken to avoid bus contention because it can drive currents that would exceed maximum limits. The high drive will also create fast edges into light loads; therefore, routing and load conditions should be considered to prevent ringing.
