Toshiba's TLP2312 and TLP2372 Photocouplers

Toshiba Electronic Devices & Storage Corporation has introduced the industry’s first photocouplers (TLP2312 &TLP2372) for high-speed communications that can operate with a power supply as low as 2.2V. The data transfer rate of TLP2312 is 5Mbps, whereas the TLP2372 has a data transfer rate of 20Mbps. These devices were designed to work with lower voltages of the peripheral circuits even when they are used in such low-level voltage circuits as 2.5V LVCMOS.

The new device reduces the component count by eliminating the need for a separate power supply to drive the photocouplers. These new devices can be driven by a microcontroller with less power consumption as they have 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.

Housed in a 5-pin SO6 package with a maximum height of 2.3mm, the low profile device can be used in High-speed digital interfaces such as programmable logic controllers (PLCs), general purpose inverters, measuring equipment, and control equipment, etc.

Features of TLP2312 & TLP2372

Low voltage operation: VDD=2.2V to 5.5V
Low threshold input current: IFLH=1.6mA (max)
Low supply current: IDDH, IDDL =0.5mA (max)
High operating temperature rating: Topr max=125℃
High-speed data transfer rates: 5Mbps (typ.) (TLP2312) / 20Mbps (typ.) (TLP2372)
