DESCRIPTION  
The M74HCT646/648 are high speed CMOS  
OCTAL BUS TRANSCEIVERS AND REGISTERS,  
(3-STATE) fabricated in silicon gate C2MOS tech-  
nology. They have the same high speed  
performance of LSTTL combined with true CMOS  
low power consumption. These devices consist of  
bus transceiver circuits with 3-state output, D-type  
flip-flops, and control circuitry arranged for multi-  
plexed 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 on the low-  
to-high transition of the appropriate clock pin (Clock  
AB - or Clock BA). Enable (G) and direction (DIR)  
pins are provided to control the transceiver function-  
s. In the transceiver mode, data present at the  
high-impedance port may bestoredin either register  
or in both. The select controls (Select AB select BA)  
can multiplex stored and real-time (transparent  
mode) data. The direction control determines which  
bus will receive data when enable G is active (low).  
In the isolation mode (enable G high), ”A” data may  
be stored in one register and/or ”B” data may be  
storedin the other register. When anoutput function  
is disabled, the input function is still enabled and  
may be used to store and transmit data. Only one  
of the two buses, A or B, may be driven at a time.  
All inputs are equipped with protection circuits  
against static discharge and transient excess volt-  
age.This integrated circuit has input and output  
characteristics that are fully compatible with 54/74  
LSTTL logic families. M74HCT devices are de-  
signed to directly interface HSC2MOS systems with  
TTL and NMOS components. They are also plug in  
replacements for LSTTL devices giving a reduction  
of power consumption.
