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).
