description
The ’AC16953 and ’ACT16953 are inverting 16-bit
registered bus transceivers composed of two 8-bit
transceiver sections with separate control
signals.
Data flow in the A-to-B mode is controlled by
output-enable
(1OEAB
clock-enable (1CEAB and 2CEAB), and clock
(1CLKAB and 2CLKAB) inputs. When 1CEAB (or
2CEAB) is high, data storage is inhibited and the
registers retain their previous states. When
1CEAB (or 2CEAB) is low, the inverse of the data
present at the corresponding A inputs is stored in
the device on a low-to-high transition of 1CLKAB
(or 2CLKAB). If 1OEAB (or 2OEAB) is also low,
this stored data appears on the corresponding B
outputs; if 1OEAB (or 2OEAB) is high, the
corresponding
B
outputs
high-impedance state. 1OEAB (or 2OEAB) does
not affect the operation of the internal registers.
Previously stored data can be retained or new
data can be entered while the outputs are in the
high-impedance state.
and
2OEAB),
are
in
the
Data flow from B to A is controlled by 1OEBA and 2OEBA, 1CEBA and 2CEBA, and 1CLKBA and 2CLKBA in
a manner analogous to that described above for A-to-B data flow.
