description
The ’AC16473 and ’ACT16473 are inverting 18-bit
latched bus transceivers composed of two 9-bit
sections with separate control signals. For either
9-bit transceiver section, data flow in the A-to-B
mode is controlled by output enable (1OEAB or
2OEAB) and latch enable (1LEAB or 2LEAB)
inputs. When 1OEAB (or 2OEAB) is low, the
corresponding B outputs are active (high or low
logic levels). When 1OEAB (or 2OEAB) is high,
the corresponding B outputs are in the
high-impedance state. The latches retain their
prior states when 1LEAB (or 2LEAB) is high and
reflect the states of the corresponding A inputs
when 1LEAB (or 2LEAB) is low.
