Features  
Description  
• Independent Registers for A and B Buses  
• Non-Inverting  
The CD74HC646 is an octal bus transceiver/register with  
three-state non-inverting outputs. This device is a bus  
transceiver with D-type flip-flops which act as internal storage  
registers. Data on the A bus or the B bus can be clocked into  
the registers on the Low-to-High transition of either CAB or  
CBA clock inputs. Outputs enable (OE) and direction (DIR)  
inputs control the transceiver functions. Data present at the  
high impedance output can be stored in either register or both  
but only one of the two buses can be enabled as outputs at  
any one time. The select controls (SAB and SBA) can  
multiplex stored and transparent (real time) data. The  
direction control determines which data bus will receive data  
when the output enable (OE) is Low. In the high impedance  
mode (output enable High), A data can be stored in one  
register and B data can be stored in the other register. The  
clocks are not gated with the direction (DIR) and output  
enable (OE) terminals; data at the A or B terminals can be  
clocked into the storage flip-flops at any time.
