description
These 18-bit universal bus transceivers combine
D-type latches and D-type flip-flops to allow data
flow in transparent, latched, and clocked 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 data is stored in the
latch/flip-flop on the low-to-high 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. Data flow for B to A
is similar to that of A to B but uses OEBA, LEBA, CLKBA, and CLKENBA.
The B-port outputs, which are designed to source or sink up to 12 mA, include equivalent 25-
series resistors
to reduce overshoot and undershoot.
When V
CC
is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 2.1 V, OE should be tied to V
CC
through a pullup resistor;
the minimum value of the resistor is determined by the current-sinking capability of the driver.
