DESCRIPTION/ORDERING INFORMATION
This 18-bit universal bus transceiver is operational at
0.8-V to 2.7-V V
CC
, but is designed specifically for
1.65-V to 1.95-V V
CC
operation.
Data
flow
in
each
direction
output-enable
(OEAB
and
(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
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).
