description
These 18-bit universal bus transceivers combine
D-type latches and D-type flip-flops to allow data
flow
in
transparent,
latched,
clocked,
and
clock-enabled modes.
Data flow in each direction is controlled by
output-enable (OEAB and OEBA), latch-enable
(LEAB and LEBA), and clock (CLKAB and
CLKBA) inputs. The clock can be controlled by the
clock-enable (CLKENAB and CLKENBA) 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-bus data is stored in the latch/flip-flop on the
high-to-low transition of CLKAB. Output enable
OEAB is active low. When OEAB is low, the
outputs are active. When OEAB is high, the
outputs are in the high-impedance state.
