DM74AS651 • DM74AS652  
Octal Bus Transceiver and Register  
General Description  
Features  
These devices incorporate an octal transceiver and an  
octal D-type register configured to enable transmission of  
data from bus to bus or internal register to bus. The  
DM74AS651 offers 64-Industrial grade product guarantee-  
ing performance from −40°C to +85°C.  
■ Switching specifications at 50 pF  
■ Switching specifications guaranteed over full tempera-  
ture and VCC range  
■ Advanced oxide-isolated, ion-implanted Schottky TTL  
process  
These bus transceivers feature totem-pole 3-STATE out-  
puts designed specifically for driving highly-capacitive or  
relatively low-impedance loads. The high-impedance state  
and increased high-logic-level drive provide these devices  
with the capability of being connected directly to and driv-  
ing 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, bidi-  
rectional bus drivers, and working registers.  
■ 3-STATE buffer-type outputs drive bus lines directly  
■ Guaranteed performance over industrial temperature  
range (−40°C to +85°C) in 64-grade products  
The registers in the DM74AS651 and DM74AS652 are  
edge-triggered D-type flip-flops. On the positive transition  
of the clock (CAB or CBA), the input data is stored.  
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.
