PCAL6416AHF,128 (NXP)
Расширитель I/O, 16бит, 400 кГц, I2C, 1.65 В, 5.5 В, HWQFN
The PCAL6416AHF,128 is a 16-bit I/O Expander provides remote I/O expansion for most microcontroller families via the I?C-bus interface. The NXP I/O expander provides a simple solution when additional I/Os are needed while keeping interconnections to a minimum. In addition to providing a flexible set of GPIOs, it simplifies interconnection of a processor running at one voltage level to I/O devices operating at a different (usually higher) voltage level. The PCAL6416A has built-in level shifting feature that makes this device extremely flexible in mixed signal environments where communication between incompatible I/O voltages is required. Its wide VDD range of 1.65 to 5.5V on the dual power rail allows seamless communications with next-generation low voltage microprocessors and microcontrollers on the interface side (SDA/SCL) and peripherals at a higher voltage on the port side.
- Low standby current consumption
- Schmitt-trigger action allows slow input transition and better switching noise immunity
- Open-drain active LOW interrupt output (INT)
- Internal power-ON reset
- Power-up with all channels configured as inputs
- No glitch on power-up
- Latched outputs with 25mA drive maximum capability for directly driving LEDs
- Latch-up performance exceeds 100 mA per JESD 78, class II
- Bank selectable push-pull or open-drain output stages
- Read-only register identifies the source of an interrupt
- Input port register values changes are kept until the input port register is read
- Floating input or pull-up/pull-down resistor enable
- Mask prevents the generation of the interrupt when input changes state
- 100kR Pull-up/down resistor
