PCA9698BS - 40-bit Fm+ I2C-bus advanced I/O port

Download the PCA9698BS datasheet PDF. This datasheet also covers the PCA9698 variant, as both devices belong to the same 40-bit fm+ i2c-bus advanced i/o port family and are provided as variant models within a single manufacturer datasheet.

Description

The PCA9698 provides 40-bit parallel input/output (I/O) port expansion for I2C-bus applications organized in 5 banks of 8 I/Os.

At 5 V supply voltage, the outputs are capable of sourcing 10 mA and sinking 25 mA with a total package load of 1 A to allow direct driving of 40 LEDs.

Features

  • 1 MHz Fast-mode Plus I2C-bus serial interface.
  • Compliant with I2C-bus Fast-mode (400 kHz) and Standard-mode (100 kHz) NXP Semiconductors PCA9698 40-bit Fm+ I2C-bus advanced I/O port with RESET, OE and INT.
  • 2.3 V to 5.5 V operation with 5.5 V tolerant I/Os.
  • 40 configurable I/O pins that default to inputs at power-up.
  • Outputs: ‹ Programmable totem-pole (10 mA source, 25 mA sink) or open-drain (25 mA sink) with controlled edge rate output structure.

PCA9698 40-bit Fm+ I2C-bus advanced I/O port with RESET, OE and INT Rev. 3 — 3 August 2010 Product data sheet 1. General description The PCA9698 provides 40-bit parallel input/output (I/O) port expansion for I2C-bus applications organized in 5 banks of 8 I/Os. At 5 V supply voltage, the outputs are capable of sourcing 10 mA and sinking 25 mA with a total package load of 1 A to allow direct driving of 40 LEDs. Any of the 40 I/O ports can be configured as an input or output. The PCA9698 is the first GPIO device in a new Fast-mode Plus (Fm+) family. Fm+ devices offer higher frequency (up to 1 MHz) and longer, more densely populated bus operation (up to 4000 pF).
