PCA8550 4-bit multiplexed/1-bit latched 5-bit I2C EEPROM

PCA8550 Description

INTEGRATED CIRCUITS PCA8550 4-bit multiplexed/1-bit latched 5-bit I2C EEPROM Product specification 1998 Sep 29 Philips Semiconductors Philips Semic.
The primary function of the 4-bit 2-to-1 I2C multiplexer is to select either a 4-bit input or data from a non-volatile register and drive this value o.

PCA8550 Features

* 4-bit 2-to-1 multiplexer, 1-bit latch
