DYNAMIC CHARACTERISTICS
7V < VBAT < 16V; –40°C < Tamb < +125°C; –2V < Vbus < +9V; 1.4 kΩ < Rld < 12 kΩ
BUS: 250 Ω < RL < 1.6 kΩ; 3nF < CL < 17nF; 1.7 µs < (RL * CL) < 5.2 µs
Bus load A: RL = 1.38 kΩ, CL = 3.3 nF; Bus load B: RL = 300Ω, CL = 16.5 nF
R/F pin: Rs = 56 kΩ; INH loaded with 100 kΩ and 30pF to GND
RX pin: Rd = 3.9 kΩ to 5V; CL = 30pF to GND; NSTB = 5V; 4X/LOOP = 0V
Typical values reflect the approximate average value at VBAT = 13V and Tamb = 25°C; unless otherwise specified.
NSTB and 4X/LOOP rise and fall times < 10 ns.
