TLP115A
High Speed, Long Distance Isolated Line Receiver Microprocessor System Interfaces Digital Isolation For A / D, D / A Conversion Computer-Peripheral Interfaces Ground Loop Elimination
The TOSHIBA mini flat coupler TLP115A is a small outline coupler, suitable for surface mount assembly. TLP115A consists of a high output power GaAAs light emitting diode, optically coupled to an integrated high gain, high speed shielded photo detector whose output is an open collector schottky clamped transistor. The shield, which shunts capacirively coupled common noise to ground, provides a guaranteed transient immunity specification of 1000V / s. l Input current thresholds: IF = 5mA (max.) l Switching speed: 10MBd (typ.) l Common mode transient immunity: 1000V / s (min.) l Guaranteed performance over temp. : 0~70C l Isolation voltage: 2500Vrms (min.) l UL recognized: UL1577, file no.

(Note 4) Device considered a two-terminal device: Pins 1 and 3 shorted together, and pins 4, 5 and 6 shorted together. (Note 5) The VCC supply voltage to each TLP115A isolator must be bypassed by 0.1F capacitor. This can be either a ceramic or solid tantalum capacitor with good high frequency characteristic and should be connected as close as possible to package VCC and GND pins of each device. (Note 6) Maximum electrostatic discharge voltage for any pins: 180V(C = 200pF, R = 0)
