DM74ALS646  
Octal 3-STATE Bus Transceiver and Register  
General Description  
Features  
This device incorporates an octal bus transceiver and an  
octal D-type register configured to enable multiplexed  
transmission of data from bus to bus or internal register to  
bus.  
■ Switching specifications at 50 pF  
■ Switching specifications guaranteed over full tempera-  
ture and VCC range  
■ Advanced oxide-isolated, ion-implanted Schottky TTL  
This bus transceiver features totem-pole 3-STATE outputs  
designed specifically for driving highly-capacitive or rela-  
tively low-impedance loads. The high-impedance state and  
increased high-logic level drive provides this device with  
the capability of being connected directly to and driving the  
bus lines in a bus-organized system without the need for  
interface or pull-up components. They are particularly  
attractive for implementing buffer registers, I/O ports, bidi-  
rectional bus drivers, and working registers.  
process  
■ 3-STATE buffer outputs drive bus lines directly  
■ Multiplexed real-time and stored data  
■ Independent registers for A and B buses  
The registers in the DM74ALS646 are edge-triggered D-  
type flip-flops. On the positive transition of the clock (CAB  
or CBA), the input bus data is stored into the appropriate  
register. The CAB input controls the transfer of data into  
the A register and the CBA input controls the B register.  
The SAB and SBA control pins are provided to select  
whether real-time data or stored data is transferred. A LOW  
input level selects real-time data, and a HIGH level selects  
stored data. The select controls have a “make before  
break” configuration to eliminate a glitch which would nor-  
mally occur in a typical multiplexer during the transition  
between store and real-time data.  
The enable G and direction control pins provide four modes  
of operation: real-time data transfer from bus A to B, real-  
time data transfer from bus B to A, real-time bus A and/or B  
data transfer to internal storage, or internally stored data  
transfer to bus A or B.  
When the enable G pin is LOW, the direction pin selects  
which bus receives data. When the enable G pin is HIGH,  
both buses become disabled yet their input function is still  
enabled.
