General Description

The LVTH16652 consists of sixteen bus transceiver circuits with D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal registers. Each byte has separate control inputs which can be shorted together for full 16-bit operation. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes to the HIGH logic level. Output Enable pins (OEAB, OEBA) are provided to control the transceiver function (see Functional Description).
