description
These devices are 16-bit registered transceivers
that contain two sets of D-type flip-flops for
temporary storage of data flowing in either
direction. The device can be used as two 8-bit
tranceivers or one 16-bit transceiver. Separate
clock (CLKAB or CLKBA) and output-enable
(OEAB or OEBA) inputs are provided for each
register to permit independent control in either
direction of data flow.
The A-to-B Enable (CEAB) input must be low in
order to enter data from A or to output data to B.
If both CEAB and CLKAB are low, then B port will
have the level of A port prior to the most recent
low-to-high transition of CLKAB. Data flow from B
to A is similar, but requires the use of CEBA,
CLKBA, and OEBA inputs.
To avoid false clocking of the flip-flops, CE should not be switched from high to low while CLK is high.
The 74AC16470 is packaged in TI shrink small-outline package (DL), which provides twice the I/O pin count and
functionality of standard small-outline packages in the same PCB area.
The 54AC16470 is characterized over the full military temperature range of –55
°
C to 125
°
C. The 74AC16470
is characterized for operation from –40
°
C to 85
°
C.
