TEXAS INSTRUMENTS PCA9539PWR I/O Expander, 16bit, 400 kHz, I2C, SMBus, 2.3 V, 5.5 V, TSSOP
TEXAS INSTRUMENTS
The PCA9539PWR is a 16-bit I/O Expander for the two-line bidirectional bus (I²C) is designed for 2.3 to 5.5V VCC operation. It provides general-purpose remote I/O expansion for most microcontroller families via the I²C interface [serial clock (SCL), serial data (SDA)]. The PCA9539 consists of two 8-bit configuration (input or output selection), input port, output port and polarity inversion (active-high or active-low operation) registers. At power-on, the I/Os are configured as inputs. The system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding Input or output register. The polarity of the input port register can be inverted with the polarity inversion register. All registers can be read by the system master. The system master can reset the PCA9539 in the event of a time-out or other improper operation by asserting a low in the RESET input. Open-drain active-low interrupt (INT)\ output Active-Low Reset Input Compatible with most microcontrollers Polarity inversion register Address by 2 hardware address pins for use of up to 4 devices Latched outputs with high-current drive capability for directly driving LEDs Latch-up performance exceeds 100mA per JESD 78, class II 5V Tolerant i/o ports 1μA Maximum low standby-current consumption Green product and no Sb/Br Chip Configuration: 16bit Bus Frequency: 400kHz IC Interface Type: I2C, SMBus Supply Voltage Min: 2.3V Supply Voltage Max: 5.5V Interface Case Style: TSSOP No. of Pins: 24Pins No. of I/O's: 16I/O's Packaging: Cut Tape Product Range: - Automotive Qualifications Standard: - MSL: MSL 1 - Unlimited Supply Voltage Range: 2.3V to 5.5V SVHC: No SVHC (15-Jun-2015) Find similar products grouped by common attribute
