Not production tested. 2Sample tested during initial release and after any redesign or process change that may affect this parameter. All input signals are measured with tr = tf = 5 ns (10% to 90% of VDD) and timed from a voltage level of (VIL +VIH)/2. 3SDO; R PULLUP = 5 k Ω, C L = 15 pF. Specifications subject to change without notice. (VDD = 10.8 V to 16.5 V, VSS = –10.8 V to –16.5 V; VSS = –15 V ±10%; GND = 0 V; RL = 5 kΩ and CL = 220 pF to GND. All specifications TMIN to TMAX, unless otherwise noted.) |
