S-7760A www.ablicinc.com © ABLIC Inc., 2007-2018 PROGRAMMABLE PORT CONTROLLER (PORT EXPANDER WITH BUILT-IN E2PROM CIRCUIT) Rev.3.0_00 The S-7760A is a programmable port controller IC comprised of an E2PROM, a control circuit for data output, a circuit to prevent malfunction caused by low power supply voltage and others. This IC operates at 400 kHz and interfaces with exteriors via I2C-bus, controls an 8ch digital output with a serial signal. Among the digital output ports of 8 channels, the lower 4 channels have a timer function so that at each port, users are able to set the default value and inverted delay time. In the higher 4 channels, setting the fixed output is available at each port. The default value is maintained despite power-off because this IC has an E2PROM. The S-7760A is able to be used to control ON/OFF for the chips surrounding MPU and to output the default data that devices fundamentally have.  Features Operating voltage range: 2.3 to 4.5 V 8ch digit...
