General description

The 74ALVCH16652 consists of 16 non-inverting bus transceiver circuits with 3-state outputs, D-type flip-flops and control circuitry arranged for multiplexed transmission of data directly from the data bus or from the internal storage registers.

Data on the ?A? or ?B?, or both buses, will be stored in the internal registers, at the appropriate clock inputs (nCPAB or nCPBA) regardless of the select inputs (nSAB and nSBA) or output enable (nOEAB and nOEBA) control inputs.

Depending on the select inputs nSAB and nSBA data can directly go from input to output (real-time mode) or data can be controlled by the clock (storage mode), when OE inputs permit this operating mode.

The output enable inputs nOEAB and nOEBA determine the operation mode of the transceiver. When nOEAB is LOW, no data transmission from nBn to nAn is possible and when nOEBA is HIGH, no data transmission from nBn to nAn is possible.

When nSAB and nSBA are in the real-time transfer mode, it is also possible to store data without using the internal D-type flip-flops by simultaneously enabling nOEAB and nOEBA. In this configuration each output reinforces its input.

Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
