Octal Transceivers and Registers with TRI-STATE®  
Outputs  
General Description  
Features  
n Independent registers for A and B buses  
n Multiplexed real-time and stored data  
The ’ABT646 consists of bus transceiver circuits with  
TRI-STATE, D-type flip-flops, and control circuitry arranged  
for multiplexed transmission of data directly from the input  
bus or from the internal registers. Data on the A or B bus will  
be clocked into the registers as the appropriate clock pin  
goes to a high logic level. Control OE and direction pins are  
provided to control the transceiver function. In the trans-  
ceiver mode, data present at the high impedance port may  
be stored in either the A or the B register or in both. The se-  
lect controls can multiplex stored and real-time (transparent  
mode) data. The direction control determines which bus will  
receive data when the enable control OE is Active LOW. In  
the isolation mode (control OE HIGH), A data may be stored  
in the B register and/or B data may be stored in the A regis-  
ter.  
n A and B output sink capability of 48 mA, source  
capability of 24 mA  
n Guaranteed multiple output switching specifications  
n Output switching specified for both 50 pF and 250 pF  
loads  
n Guaranteed simultaneous switching noise level and  
dynamic threshold performance  
n Guaranteed latchup protection  
n High impedance glitch free bus loading during entire  
power up and power down cycle  
n Nondestructive hot insertion capability  
n Standard Microcircuit Drawing (SMD) 5962-9457701
