The 8- and 16-bit devices are pin-to-pin and I
compatible with the NXP PCF857X, the lower-cost PCA857X,
and the Fast-mode Plus, 1-MHz PCA967X series. Various
enhancements make software changes necessary (see
application note AN469).
The open-drain interrupt output is activated when any input
state differs from its corresponding input port register state.
The output notifi es the system master when an input state
has changed. In applications that require the interrupt and
an external hardware reset, the NXP PCA9537, PCA9538, and
PCA9539 are recommended alteranatives.
Three hardware pins (A0, A1, A2) vary the fi xed I
and allow up to eight devices to share the same I
address on the PCA955 is the same as the PCA9554, so up to
eight of these devices in any combination can share the same
I
All four devices have push-pull outputs that sink 25 mA and
source 10 mA. This is different from the quasi-bidirectional
outputs that sink 25 mA with limitations and only source
100 μA. For portable applications, The NXP PCA9534 and
PCA9535 are identical to the PCA9554/54A and the PCA9555,
but the I/O 100-kΩ internal pull-up resistor is removed to
reduce current consumption when the outputs are held low.
The functional diagram and schematic for the PCA9536,
PCA9554/54A, and PCA9555 are the same except that the
PCA9555 has two 8-bit blocks of I/O and the PCA9536 has half
an 8-bit block of I/O.
The fi xed I
that of the PCA9554A, allowing up to sixteen of these devices
(eight of each type) on the same I
