SEMICONDUCTOR TECHNICAL DATA  
The MC74LCX646 is a high performance, non–inverting octal  
transceiver/registered transceiver operating from a 2.7 to 3.6V supply.  
High impedance TTL compatible inputs significantly reduce current  
loading to input drivers while TTL compatible outputs offer improved  
LOW–VOLTAGE CMOS  
OCTAL TRANSCEIVER/  
REGISTERED TRANSCEIVER  
switching noise performance. A V specification of 5.5V allows  
I
MC74LCX646 inputs to be safely driven from 5V devices. The  
MC74LCX646 is suitable for memory address driving and all TTL level  
bus oriented transceiver applications.  
Data on the A or B bus will be clocked into the registers as the  
appropriate clock pin goes from a LOW–to–HIGH logic level. Output  
Enable (OE) and DIR pins are provided to control the transceiver outputs.  
In the transceiver mode, data present at the high impedance port may be  
stored in either the A or the B register or in both. The select controls (SBA,  
SAB) can multiplex stored and real–time (transparent mode) data. The  
direction control (DIR) determines which bus will receive data when the  
enable OE is active LOW. In the isolation mode (OE HIGH), A data may  
be stored in the B register or B data may be stored in the A register. Only  
one of the two buses, A or B, may be driven at one time.
