description
The ’AC16471 and ’ACT16471 are inverting 16-bit
registered bus transceivers composed of two 8-bit
sections with separate control signals. For either
8-bit transceiver section, data flow in the A-to-B
mode is controlled by output-enable (1OEAB or
2OEAB), direction-enable (1DEAB or 2DEAB),
and clock (1CLKAB or 2CLKAB) inputs.
When 1DEAB (or 2DEAB) is high, storage of the
current A-bus data is inhibited and the
corresponding
B
outputs
high-impedance state.When 1DEAB (or 2DEAB)
is low, the register contents and the output buffers
are controlled by 1CLKAB (or 2CLKAB) and
1OEAB (or 2OEAB). A low level on 1CLKAB (or 2
CLKAB) inhibits loading of the registers with the
current A-bus data; a low-to-high transition on
1CLKAB (or 2CLKAB) causes the corresponding
registers to be loaded with the current A-bus data.
If 1OEAB (or 2OEAB) is low, the corresponding B
outputs reflect the inverse of the register contents.
A high level on 1OEAB (or 2OEAB) causes the B
outputs to be in the high-impedance state.
