MAX3280E/MAX3281E/ ±15kV ESD-Protected 52Mbps, 3V to 5.5V, MAX3283E/MAX3284E SOT23 RS-485/RS-422 True Fail-Safe Receivers
Switching Characteristics
(VCC = 3V to 5.5V, VL = VCC, TA = TMIN to TMAX, unless otherwise noted. Typical values are at VCC = 5V and TA = +25°C.) (Notes 2, 3)

ENABLE/DISABLE TIME FOR MAX3281E/MAX3283E
Receiver Enable to Output Low tPRZL Figure 2, CL = 15pF 500 ns Receiver Enable to Output High tPRZH Figure 2, CL = 15pF 500 ns Receiver Disable Time from Low tPRLZ Figure 2, CL = 15pF 500 ns Receiver Disable Time from High tPRHZ Figure 2, CL = 15pF 500 ns
Note 2:
Parameters are 100% production tested at +25°C, limits over temperature are guaranteed by design.
Note 3:
All currents into the device are positive; all currents out of the device are negative. All voltages are referenced to device ground, unless otherwise noted.
Note 4:
VCM is the common-mode input voltage. VID is the differential input voltage.
Note 5:
Not production tested. Guaranteed by design.
Note 6:
See Table 2 for MAX3284E data rates with VL < VCC.
Typical Operating Characteristics
