TC4431/TC4432 ELECTRICAL SPECIFICATIONS (CONTINUED) Electrical Characteristics: Over operating temperature range with 4.5V ≤ VDD ≤ 30V, unless otherwise noted. Symbol Parameter Min Typ Max Units Test Conditions Input VIH Logic 1, High Input Voltage 2.4 —— V VIL Logic 0, Low Input Voltage —— 0.8 V IIN Input Current (Note 1) -1 — 1 µA0V ≤ VIN ≤ 12V Output VOH High Output Voltage VDD – 1.2 —— VIOUT = 100mA VOL Low Output Voltage —— 0.025 V RO Output Resistance —— 10 Ω IOUT = 10mA, VDD = 30V Switching Time (Note 2) tR Rise Time —— 60 nsec Figure 3-1 tF Fall Time —— 70 nsec Figure 3-1 tD1 Delay Time —— 100 nsec Figure 3-1 tD2 Delay Time —— 110 nsec Figure 3-1 Power Supply IS Power Supply Current — — — — 6 0.7 mA VIN = 3V VIN = 0V VS Start-up Threshold — 8.4 10 V VDO Drop-out Threshold 7 7.7 — V Note 3 Note 1: For inputs >12V, add a 1k Ω resistor in series with the input. See “Typical Characteristics” graph for input current. 2: Switching times are ensured by design. 3: For operation below 7V, pin 3 (LOCK DIS) should be tied to ground to disable the lockout and start-up circuit, otherwise, pin 3 must be left floating. |
