The 'AC646 consist of registered bus transceiver circuits, with outputs, D-type flip-flops and control circuitry providing multiplexed transmission of data directly from the input bus or from the internal storage registers. Data on the A or B bus will be loaded into the respective registers on the LOW-to-HIGH transition of the appropriate clock pin (CPAB or CPBA). The four fundamental data handling functions available are illustrated in .

Features

Independent registers for A and B buses
Multiplexed real-time and stored data transfers
TRI-STATE outputs
300 mil slim dual-in-line package
Outputs source/sink 24 mA
'ACT646 has TTL compatible inputs
