Preliminary specification
AU5783
DYNAMIC CHARACTERISTICS
7 V < VBAT < 16 V; –40°C < Tamb < +125°C; –2 V < Vbus < +9 V; 1.4 kΩ < Rld < 12 kΩ
BUS: 250 Ω < RL < 1.6 kΩ; 3 nF < CL < 17 nF; 1.7 µs < (RL * CL) < 5.2 µs
Bus load A: RL = 1.38 kΩ, CL = 3.3 nF; Bus load B: RL = 300 Ω, CL = 16.5 nF
R/F pin: Rs = 56 kΩ ± 1%; INH loaded with 100 kΩ and 30 pF to GND
RX pin: Rd = 3.9 kΩ to 5 V; CL = 30 pF to GND; NSTB = 5 V; 4X/LOOP = 0 V
Typical values reflect the approximate average value at VBAT = 13 V and Tamb = 25°C, unless otherwise specified.
NSTB and 4X/LOOP rise and fall times < 10 ns.
