DESCRIPTION
The LVT646 is a high-performance Bi CMOS product designed for VCC operation at 3.3V. This device consists of bus transceiver circuits with 3-State outputs, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or the internal registers. Data on the A or B bus will be clocked...
