Dual-Wire Bus Buffer IC increases load limit.

Press Release Summary:




RoHS-compliant IES5501 extends and expands bus load limit of 2-wire bus systems - I2C, SMBus, PMBus, and IPMB - by buffering clock and data lines. Using analog IC design principles for digital bus, product features input-output offset voltages that permit use in cascade, multidrop bus, or daisy chain configurations. Fully I2C-compliant IC does not impose additional restrictions on bus logic levels, and analog design facilitates level shifting of bus voltages from 1.8-15 V.



Original Press Release:



New 2-Wire Bus Buffer Now in Full Production



Hendon Semiconductors announces the IES5501 2-wire bus buffer IC is in full production. One of the new Bus Buffers in the IES550x family, the IES5501 is compatible for extending and expanding I2C(1), SMBus(2), PMBus(2), IPMB and other similar 2-wire bus systems.

Using analog IC design principles for a digital bus, the IES5501 features low input-output offset voltages, allowing their use in a cascade or "daisy chain" fashion simplifying the engineers design process. With the low noise susceptibility and a wide allowable voltage range, the IES5501 makes it easier to create larger bus networks without exceeding the maximum allowed bus capacitance for these types of bus.

The function of the IES5501 Bus buffer is to extend the bus load limit by buffering the clock (SCL) and data (SDA) lines. The IES5501 finds its place in 2-wire bus systems within telecommunication systems (including ATCA), CompactPCI, VME bus systems, RAID products, power management systems, backplane management systems, bus switch/multiplexing buffering and for bus voltage level translation. The IES5501 significantly increases system noise margins on the intelligent platform management bus (IPMB) and are therefore excellent for implementing cost effective IPMB architectures.

The IES5501 bus buffer has superior switching times and input to output connection control is supported using the enable pin. The advanced analog design of the IES5501 enables easy level shifting of bus voltages, a wide range allowed between 1.8V and 15V. The application or removal of power to the device will not interfere with other bus activity.

The IES5501 is offered in 8-pin SO and 8-pin MSOP, all are RoHS compliant with samples available and is in full production.
