DM74ALS652  
Octal 3-STATE Bus Transceiver and Register  
General Description  
This device incorporates an octal transceiver and an octal  
D-type register configured to enable transmission of data  
from bus to bus or internal register to bus.  
Features  
■ Switching specifications at 50 pF  
■ Switching specifications guaranteed over full tempera-  
ture and VCC range  
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 level logic drive provide this device with the  
capability of being connected directly to and driving the bus  
lines in a bus organized system without need for interface  
or pull-up components. They are particularly attractive for  
implementing buffer registers, I/O ports, bidirectional bus  
drivers, and working registers.  
■ Advanced oxide-isolated, ion-implanted Schottky TTL  
process  
■ 3-STATE buffer-type outputs drive bus lines directly  
■ Independent registers and enables for A and B buses  
■ Multiplexed real-time and stored data  
The registers in the DM74ALS652 are edge-triggered D-  
type flip-flops. On the positive transition of the clock (CAB  
or CBA), the input data is stored into the appropriate regis-  
ter. 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 stored and real-time data.  
The enable (GAB and GBA) 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 internal stored  
data transfer to bus A and/or B.
