All characteristics are measured with zero common-mode input voltage, unless otherwise specified. ‡ VCC MAX = 30 V for non-V devices and 32 V for V-suffix devices. § The voltage at either input or common-mode should not be allowed to go negative by more than 0.3 V. The upper end of the common-mode voltage range is VCC+ − 1.5 V, but either or both inputs can go to 30 V (32 V for V-suffix devices) without damage. switching characteristics, VCC = 5 V, TA = 25°C PARAMETER TEST CONDITIONS LM193 LM293, LM293A LM393, LM393A LM2903 UNIT TYP Response time RL connected to 5 V through 5.1 kΩ, 100-mV input step with 5-mV overdrive 1.3 µs Response time RL connected to 5 V through 5.1 kΩ, CL = 15 pF¶, See Note 8 TTL-level input step 0.3 µs ¶ CL includes probe and jig capacitance. NOTE 8: The response time specified is the interval between the input step function and the instant when the output crosses 1.4 V. |
