| Part Number | PCA9539 |
| Manufacturer | Texas Instruments |
| Description | This 16-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 2.3-V to 5.5-V 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, . |

| Title | Low-voltage 16-bit I2C and SMBus low-power I/O expander |
| Description | The PCA9539 provides 16 bits of General Purpose Input/Output (GPIO) expansion with interrupt and reset for I²C-bus/SMBus applications. It is designed for a wide voltage range of 2.3 V to 5.5 V. Nexperia GPIO expanders provide an elegant solution when additional IOs are needed while keeping the inter. |
| Features |
and benefits
• I²C-bus to parallel port expander • Operating power supply voltage range of 2.3 V to 5.5 V • Ultra low standby current consumption: • 1 µA (maximum) • Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs • Vhys = 0.10 × VCC (typical) • Noise filter on SCL and SDA inputs • 5 V tolerant I/Os • 16 I/O pins which power up conf. |
