MAX13020/MAX13021
±60V Fault-Protected LIN Transceivers
TIMING CHARACTERISTICS (continued)
(V_BAT = +5V to +38V, T_A = -40°C to +125°C, unless otherwise noted. Typical values are at V_BAT = +12V and T_A = +25°C. Positive
currents flow into the device.)

Note 1: Guaranteed by design for V_BAT = V_LIN = +27V.
Note 2: Selected bit time, t_BIT = 50µs or 96µs (20kbaud or 10.4kbaud). Bus load conditions (C_BUS / R_BUS): 1nF/1kΩ, 6.8nF/660Ω,
10nF/500Ω.
Note 3: t_GOTONORM is measured from rising edge of N_SLP to RXD active.
Note 4: t_GOTOSLEEP is measured from falling edge of N_SLP to RXD high impedance.
(V_BAT = +12V and T_A = +25°C, unless otherwise noted.)
