IES5502 Dual Bi-Directional Bus Buffer with Hot Insertion Logic NOW RELEASED Hendon Semiconductors expands its range of its two-wire bus buffer with the introduction of the IES5502, fast dual bi-directional bus buffer with hot insertion logic. The hot insertion logic with pre-charge feature prevents data corruption on the bus during I/O card insertion into live backplanes. The features of the IES5502 make them well suited for the computing or networking systems such as backplane applications where there are differences in voltage levels and speeds. The unique function of the IES5502 provides one of the fastest response times of such bi-directional buffers without the use of Rise Time Accelerators (RTA). The RTA when combined with low noise margins may cause glitches outside of the I2C specification. Similarly to the IES5501, the IES5502 is a fully I2C compliant bus buffer and supports a wide range of other two-wire bus systems including fast modes (operation in excess of 1MHz). IES5502 is offered in 8-pin SO and MSOP package. For more information visit our IES5502 product page or contact us for more details.

IES5505 / IES5515 Simple 2-wire Bus Buffer NOW RELEASED Hendon Semiconductors recently released the IES5505 and IES5515, a simple isolating buffer for two-wire bus system. With the growth of application adopting the two-wire bus system, this is the solution for a simple application where a fully-featured bus buffer is not required. The only difference between the IES5505 and IES5515 is its maximum pull-down capability. The IES5505 has 4mA is suitable for I2C (both standard and fast modes), PMBUS and SMBUS. The IES5515 with a pull-down capability of 30mA is ideal for FM+ application as well. The DIRECTION pin on the ICs allow Master devices to be placed on both side of the buffer by allowing the uni-directional clock to be reversed. Both IES5505 and IES5515 also features an ENABLE which allows different section of the bus to be isolated and brought on-line successively. By combining the low cost price of IES5505/IES5515 compared to other bus buffers, a simple cost-effective solution can be easily achieved. Their simple characteristics are suitable for quick implementation in most two-wire bus application. The IES5505 and IES5515 are available in 8-lead SO8 and 8-lead MSOP package. Engineering samples and production builds are available now. For more information visit our IES5505 - IES5515 product page or contact us for more details.

IES5541A NOW RELEASED The IES5541A relay driver with contact protection integrated circuit from Hendon Semiconductors is now fully released. It is capable of extending relay contact lifetime and delivering higher relay reliability. The function of the IES5541A is to control the relay switching at mains zero crossing and firing a triac connected across the relay contacts for a duration of 8 half-mains cycle each time the relay turns on when whenever arcing is detected during relay turns off. In-house testing shows relay contacts electrical lifetime extends to over 1 million switches. The IES5541A and its contact protection circuit are compatible with most power relays. Ideal for AC mains temperature control applications where high currents are constantly switched and excessive EMI is to be avoided. Typical applications include home/kitchen appliances and industrial control/ motor switching. The IES5541A is available in DIP8 and SO8 packages, all RoHS compliant.
