All characteristics are measured with zero common-mode input voltage unless otherwise specified. ** The voltage at either input or common-mode should not be allowed to go negative by more than 0.3V. The upper end of the common - mode voltage range is VCC -1.5V, but either or both inputs can go to 30V without damage. Switching Charactristics Vcc=5V, Т A=25 °C Parameter Test conditions Min Typ Max Units Response time RL connected to 5V through 5.1 k Ω, 100-mV input step with 5-mV overdrive 1.3 µs CL=15pF* (See Note 1) TTL-level input step 0.3 * CL includes probe and jig capacitance. Note 1: The response time specified is the interval between the input step function and the instant when the output crosses 1.4V. BEIJING ESTEK ELECTRONICS CO.,LTD 2 |
