TA8513P

The TA8513P is a kind of fiber optic transmitting peripheral IC. It is LED drive circuit for optical transmittion. There are some features as follows: (1)TTL interface; (2)data rate: up to 20 Mb/s (NRZ code).

The following is about the maximum ratings of TA8513P(Ta=25): (1)storage temperature, Tstg: -55 to 150; (2)operating temperature, Topr: -40 to 85; (3)power supply, VCC: -0.5 to 7 V; (4)input voltage, VIN: -0.5 to VCC V; (5)LED terminal voltage, VLED: VCC-2.5 to VCC V; (6)package allowable loss: 0.9 W; (7)soldering temperature, Tsol: 260.

The last one is about the electrical characteristics about TA8513P (Ta=25, VCC=5 V, VLED=VCC=2.5 V): (1)current consumption, ICC: 1.2 mA typ when VCC=VLED=5.25 V, B2, B4, B8, B9=OPEN; 6 mA min, 10 mA typ and 14 mA max at VCC=VLED=5.25 V, VB9=5.25 V; 15 mA min, 26 mA typ and 37 mA max at VCC=VLED=5.25 V, VB8=5.25 V; 29 mA min, 42 mA typ and 55 mA max at VCC=VLED=5.25 V, VB2=5.25 V; 45 mA min, 64 mA typ and 83 mA max at VCC=VLED=5.25 V, VB4=5.25 V; (2)current limiting resistor: R17: 1.8 k typ; R18: 3 k typ; R19: 4.9 k typ; R20: 14.8 k typ; (3)LED output current, ILED: 5 mA min, 7 min typ and 9 mA max at VB9=5.0 V; 15 mA min, 20 min typ and 25 mA max at VB8=5.0 V; 24 mA min, 32 min typ and 40 mA max at VB2=5.0 V; 37 mA min, 50 min typ and 63 mA max at VB4=5.0 V; (4)LED cut-off current, Ioff: 12A max.
