KUALA LUMPUR, June 29 -- Toshiba Electronic Devices & Storage Corporation (Toshiba) has released the industry’s first photocouplers for high-speed communications, operating with as low as 2.2V power supply.
According to Toshiba in a statement, the two devices are ‘TLP2312’ and ‘TLP2372’.
With shipment beginning today, TLP2312 delivers a typical data transfer rate of 5Mbps and TLP2372, at 20Mbps.
The products are designed to operate at low voltage, starting at 2.2V, so as to work with the lower voltages of the peripheral circuits, even when used in such low level voltage circuits as 2.5V LVCMOS.
This approach eliminates the need for a separate power supply to drive the photocouplers, reducing the component count.
With a low threshold input current of 1.6mA (max), and low supply current of 0.5mA (max) in their -40℃ and +125℃ operating temperature range, the new photocouplers can be directly driven by microcontrollers, reducing power consumption.
The devices can be used in high-speed digital interfaces including programmable logic controllers, general purpose inverters, measuring equipment and control equipment.
