This 18-bit universal bus transceiver is operational at  
0.8-V to 2.7-V VCC, but is designed specifically for  
1.65-V to 1.95-V VCC operation.

Data flow in each direction is controlled by  
output-enable (OEAB and OEBA), latch-enable  
(LEAB and LEBA), and clock (CLKAB and CLKBA)  
inputs. For A-to-B data flow, the device operates in  
the transparent mode when LEAB is high. When  
LEAB is low, the A data is latched if CLKAB is held at  
a high or low logic level. If LEAB is low, the A data is  
stored in the latch/flip-flop on the low-to-high  
transition of CLKAB. When OEAB is high, the outputs  
are active. When OEAB is low, the outputs are in the  
high-impedance state.

Data flow for B to A is similar to that of A to B, but uses OEBA, LEBA, and CLKBA. The output enables are  
complementary (OEAB is active high and OEBA is active low).
