Product Description
PCAL6416AHF Integrated Circuit Chip 16-Bit Level Translating I/O Expander HWQFN24
Product Description
PCAL6416AHF is a 16-bit general-purpose I/O expander that provides remote I/O expansion for most microcontroller families via the I2C-bus interface.
PCAL6416AHF has built-in level shifting feature that makes these devices extremely flexible in mixed signal environments where communication between incompatible I/O voltages is required. Its wide VDD range of 1.65 V to 5.5 V 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.

Key Features
- Operating power supply voltage range of 1.65 V to 5.5 V
- Allows bidirectional voltage-level translation and GPIO expansion between:
- 1.8 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P
- 2.5 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P
- 3.3 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P
- 5 V SCL/SDA and 1.8 V, 2.5 V, 3.3 V or 5 V Port P
- Low standby current consumption:
- 1.5 μA typical at 5 V VDD
- 1.0 μA typical at 3.3 V VDD
- Schmitt trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs
- 5 V tolerant I/O ports
- Active LOW reset input (RESET)
- Open-drain active LOW interrupt output (INT)
- 400 kHz Fast-mode I2C-bus
- Internal power-on reset
- Power-up with all channels configured as inputs
- No glitch on power-up
- Noise filter on SCL/SDA inputs
- Latched outputs with 25 mA drive maximum capability for directly driving LEDs
