PIN AND FUNCTION COMPATIBLE WITH  
74 SERIES 646  
This device consists of bus transceiver circuits  
with 3 state, D-type flip-flops, and control circuitry  
arranged for multiplexed transmission of data  
directly from the input bus or from the internal  
registers. Data on the A or B bus will be clocked  
into register 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 functions. In the  
transceiver mode, data present at the  
high-impedance port may be stored in 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

DESCRIPTION  
The 74LCX646 is a low voltage CMOS OCTAL  
BUS  
(3-STATE) fabricated with sub-micron silicon gate  
and double-layer metal wiring C MOS technology.  
It is ideal for low power and high speed 3.3V  
applications; it can be interfaced to 5V signal  
environment for both inputs and outputs.
