PCA9561 Product details

Description

The PCA9561 is a 20-pin CMOS device consisting of four 6-bit non-volatile EEPROM registers, six hardware pin inputs and a 6-bit multiplexed output.

Features

Selection of non-volatile register_n as source to MUX_OUT pins via I2C-bus.
I2C-bus can override MUX_SELECT pin in selecting output source.
6-bit 5-to-1 multiplexer DIP switch.
Four internal non-volatile registers.
Internal non-volatile registers programmable and readable via I2C-bus.
Six open-drain multiplexed outputs.
400 kHz maximum clock frequency.
Operating supply voltage 3.0 V to 3.6 V.
5 V and 2.5 V tolerant inputs/outputs.
Useful for Spe.
