TLP2955F
1. Applications
• Intelligent Power Module Signal Isolation
• Programmable Logic Controllers (PLCs)
• High-Speed Digital Interfacing for Instrumentation and Control Devices
2. General
The Toshiba TLP2955F consists of a GaAℓAs light-emitting diode coupled with a high-gain, high-speed photo
detector. It is housed in the DIP8 package. The detector has a totem-pole output stage with current sourcing and
sinking capabilities. The TLP2955F has an internal Faraday shield that provides a guaranteed common-mode
transient immunity of ±20 kV/µs. The TLP2955F has an buffer output. A inverter output version, the TLP2958F,
is also available. The TLP2955F satisfies 8 mm PC board spacing requirements. Absolute maximum ratings and
electrical characteristics are the same as in the TLP2955.
3. Features
(1) Buffer logic type (totem pole output)
(2) Package: DIP8
(3) Supply voltage: 3 to 20 V
(4) Threshold input current, low to high: IFLH = 1.6 mA (max)
(5) Propagation delay time: tpHL/tpLH = 250 ns (max)
(6) Common-mode transient immunity: ±20 kV/µs (min)
(7) Operating temperature: -40 to 125
(8) Isolation voltage: 5000 Vrms (min)
(9) Safety standards
UL-approved: UL1577, File No.E67349
cUL-approved: CSA Component Acceptance Service No.5A File No.E67349
VDE-approved: EN60747-5-5, EN60065 or EN60950-1 (Note 1)
Note 1: When a VDE approved type is needed, please designate the Option (D4).
