Catalyst Semiconductor has expanded its product lines to include a new family of I/O bus expanders. The first two devices in the family, the CAT9554 and CAT9554A, provide a simple and cost-effective method to address eight I²C or SMBus I/O ports. These devices help designers balance system performance, processor, and board costs for sensor, control, and LED applications in white goods, digital cameras, cellphones, PDAs, routers, hubs and servers.
The CAT9554 and CAT9554A consist of eight ports, which power up as inputs and can be configured as an input or output by writing to a register. An internal power-on reset in both devices eliminates glitches on power-up. Each I/O port is 5 V input tolerant, with a high current I/O drive sink of up to 25 mA and an I/O source of up to 10 mA, maximum. Additionally, each I/O port is compatible with logic thresholds of 2,5 V, 3,3 V and 5 V. The 8 I/O pins default to inputs at power-up.
The devices operate from 2,3 V to 5,5 V and over a -40 to 85°C temperature range. They come in 16-pin SOIC, TSSOP and 16-pad TQFN packages.
