Toshiba Launches a High Speed, Dual Polarity Input Photocoupler for Servo Motors and PLCs
ME Newswire / Businesswire

TOKYO - Tuesday, November 19th 2013

Toshiba Corporation (TOKYO:6502) today announced that it has launched "TLP2391”, a high-speed photocoupler for servo motors and programmable logic controllers (PLCs) which works with both plus and minus LED currents. Mass production is scheduled to start in December.

PLC applications accept one of two different polarity inputs: sink logic input and source logic input. The "TLP2391” supports both sink and source logic by combining two LEDs in inverse parallel, eliminating the need for a bridge circuit. The product supports 10Mbps high speed communications, twice as fast as other Toshiba dual input photocouplers1 allowing use in communications interfaces in industrial applications. The IC’s 2.3mA low input current drive (@ VCC = 3.3V) and 1mA low supply current contribute to energy efficiency.

Applications Programmable logic controllers (PLC), servo motors, and industrial automation equipment
 

Key Features of New Product

• Operating temperature: Topr = -40 to 125°C

• Supply voltage: VCC = 2.7 to 5.5V

• Supply current: ICC = 1mA

• Threshold input current:
          

IFHL = 2.3mA (VCC = 3.3V)
            

IFHL = 2.5mA (VCC = 5.0V)

• Propagation delay time: tpHL / tpLH = 100ns (max)

• Pulse width distortion: |tpHL-tpLH| = 30ns (max)

• Propagation delay skew: tpsk = 40ns (max)
 

Note: [1]: Comparison with 5Mbps speed of Toshiba dual input photocouplers, "TLP2395” and "TLP2398”.
