These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2012, February, rev.02 ILX232 Recommended Operating Conditions Symbol Rate Parameter min max VCC Supply voltage 4.5 5.5 V+ Transmitter output high voltage 5.0 - V- Transmitter output low voltage -5.0 - 0 VСС -30 30 - 60 -40 85 VTIN Transmitter input voltage VRIN Receiver input voltage ISC Transmitter short circuit output current Та Ambient temperature 5V 0.1 F 1 0.1 F 0.1 F + 3 + 4 5 V mA О С + + 0.1 F 16 C1+ V+ 2 C1- V- C2+ 6 C2- + 11 14 TTL/CM OS Intput 10 7 12 13 TTL/CM OS Output Unit 5к 9 8 0.1 F RS-232 Output RS-232 Input 5к 15 2012, February, rev.02 ILX232 Static parameters Symbol ICC Parameter Consumption current static Test conditions VCC =5.0 V VIL = 0 V Unit Rate -40 C to 85 C min max 14.0 min - 25C max 10.0 0.2 0.9 0.2 1.0 - 2.4 - 2.3 0.8 - 0.9 - mA Receiver electrical parameters Vh Hysteresis voltage VCC =5.0 V V On On (operation) voltage VO 0.1 V IOL 20 uA Voff Off (dropout) voltage VO VCC -0.1 V IOH -20 uA VOL Output low voltage IOL = 3.2 mА VСС = 4.5 V VIH = 2.4 V - 0.3 - 0.4 VOH Output high voltage IOH = -1.0 mA VСС = 4.5 V VIL = 0.8 V 3.6 - 3.5 - Input resistance VСС = 5.0 V 3.0 7.0 3.0 7.0 RI V kOhm Transmitter electrical parameters VOL Output low voltage VСС = 4.5 V VIH = 2.0 V RL = 3.0 kOhm - -5.2 - -5.0 VOH Output high voltage VСС = 4.5 V VIL = 0.8 V RL = 3.0 kOhm 5.2 - 5.0 - IIL Input low current VСС =5.5 V VIL = 0 V - -1.0 - -10.0 IIH Input high current VСС =5.5 V VIH = VСС SR Speed of output front change VСС =5.0 V СL =50 - 1000 pF RL = 3.0 - 7.0 kOhm 3.0 30 2.7 27 V/㎲ RО Output resistance VСС = V+ = V- = 0 V VO = 2 V 350 - 300 - Ohm ISC Short circuit output current VСС =5.5 V VO = 0 V VI = VСС VI = 0 V ST Speed of information transmission VСС =4.5 V СL = 1000 pF RL = 3.0 kOhm tW = 7us (for extreme -tW = 8us) 1.0 V uA 10.0 mA -50 50 140 - -60 60 120 - kbps 2012, February, rev.02 ILX232 Dynamic parameters Symbol Parameter Test conditions 25 C tPHLR (tPLHR) tPHLT (tPLHT) Unit Rate min max - 9.7 Signal propagation delay time VСС = 4.5 V when switching on (off) СL = 150 pF VIL = 0 V VIH = 3.0 V tLH = tHL 10 ns Signal propagation delay time VСС = 4.5 V when switching on (off) СL = 2500 pF VIL = 0 V VIH = 3.0 V RL = 3 kOhm tLH = tHL 10 ns 5.0 from -40 C to 85 C min max - 10 6.0 us Capacitance Parameter Symbol CIN Input capacitance CPD Dynamic capacitance VCC, Rate 5.0 9.0 Unit pF 90 Timing diagram when measuring IC dynamic parameters +3 V Rin 1.5 V 1.5 V 0V VOH 0.5Vcc 0.5Vcc Rout VOL t PHLR t PLHR Figure 3 2012, February, rev.02 ILX232 +3 V Tin 1.5 V 1.5 V 0V VOH 1.5 V 1.5 V Tout VOL t PHLT tPLHT Figure 4 Tin t SLH t SHL +3 V +3 V Tout -3 V -3 V Figure 5 tW tW tW tW TIN TOUT Control strobe Figure 6 2012, February, rev.02 ILX232 N SUFFIX PLASTIC DIP (MS - 001BB) A Dimension, mm 9 16 Symbol MIN MAX A 18.67 19.69 B 6.1 7.11 B 1 8 C F L C 5.33 D 0.36 0.56 F 1.14 1.78 G 2.54 H 7.62 -T- SEATING PLANE N G K M H D J 0.25 (0.010) M T NOTES: 1.
