18-bit Universal Bus Transceivers with 3-state Outputs
ADE-205-167A (Z)
2nd. Edition
December 1999
Description
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 bus data is stored in the latch flip flop on the high to low
transition of
CLKAB
. Output enable OEAB is active high. When OEAB is high, the B port outputs are
active. When OEAB is low, the B port 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). Active bus hold circuitry is provided to hold unused or
floating data inputs at a valid logic level.
