Support for low-voltage peripheral circuits, reducing the number of components
Reduced power consumption by enabling direct operation with MCU


Toshiba Electronic Devices & Storage Corporation announced on the 30th the TLP2312 and TLP2372, high-speed photocouplers capable of operating in parallel with low-power devices equivalent to 2.2 V. Data transfer speeds of 5 Mbps and 20 Mbps, respectively, are available for shipment on the 29th.

The two new photocouplers feature 2.5 LVCMOS technology, enabling them to operate at lower peripheral voltages even in low-voltage circuits. This also reduces component count by eliminating the need for a separate power supply to drive the photocouplers.

The operating temperature range is -40 to 125°C, the input current limit is 1.6 mA at most, and the supply current is low at 0.5 mA at most. Direct driving by an MCU can reduce power consumption.

The TLP2312 and TLP2372 photocouplers, suitable for high-speed digital interfaces such as PLCs (Programmable Logic Controllers), general-purpose inverters, measuring equipment, and control equipment, are provided in a 5-pin SO6 package with a maximum height of 2.3 mm to ensure a low profile and allow for ample component placement on the PCB.
