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. E67349

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 V
