The latch enable (LE1B, LE2B, LEA1B and LEA2B) inputs control data storage. When a latch-enable input is HIGH, the latch is transparent. When the latch enable input is LOW, the data at the input is latched and remains latched until the latch enable input is returned HIGH. Independent output enables (OE1B and OE2B allow reading from one port while writing to the other port. The FCT16260AT/CT are ideally suited for driving high capacitance loads and low impedance backplanes. The output buffers are designed with power off disable capability to allow live insertion of boards when used as backplane drivers.
