description
These devices are non-inverting 18-bit registered
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 clock (1CLKAB or 2CLKAB) inputs. When
1OEAB or 2OEAB is low, the corresponding
outputs are active (high or low ) and take on either
the current data on low-to-high transition of
1CLKAB or 2CLKAB or the previously stored data
if 1CLKAB or 2CLKAB is low.
When 1OEAB or 2OEAB is high, the corresponding outputs are in the high-impedance state. 1OEAB or 2OEAB
does not affect the operation on the internal registers. Previously stored data can be retained or new data can
be entered while the outputs are in the high-impedance state.
Data flow from B to A is similar, but uses 1OEBA and/or 2OEBA and 1 CLKBA and/or 2CLKBA.
The 74AC16474 is packaged in TI’s shrink small-outline packages (DL) with 25-mil center-to-center pin
spacings. This package provides twice the I/O pin count and functionality of a standard small-outline package
in the same PCB area.
The 54AC16474 is characterized over the full military temperature range of –55
°
C to 125
°
C. The 74AC16474
is characterized for operation from –40
°
C to 85
°
C.
