Key technical specifications
Ordering-code highlights reviewed against official manufacturer documentation.
- Function
- EIA RS-485/RS-422 differential line transceiver — one driver and one receiver, independently enableable; up to 32 transceivers on one bus; open-input fail-safe (receiver output high with inputs floating)
- Supply
- VCC = 5 V ±5% — every specification in Rev. F is at this supply; no 3.3 V specification exists in the document
- Data rate
- 30 Mbps typical (Features, Rev. F wording)
- Driver output
- Differential output 1.5 V min / 5.0 V typ into 27 Ω (RS-485 load); 2.0 V min / 5.0 V typ into 50 Ω (RS-422 load); short-circuit current 35 mA min / 250 mA max magnitude over −7 V ≤ VO ≤ +12 V
- Receiver
- Differential input threshold −0.2 V min / +0.2 V max over −7 V ≤ VCM ≤ +12 V; hysteresis 70 mV typ at VCM = 0 V; input resistance 12 kΩ min over the same common-mode range
- Supply current
- Outputs enabled 1.0 mA typ / 2.2 mA max; outputs disabled 0.6 mA typ / 1.0 mA max (digital inputs at GND or VCC)
- Driver timing
- Propagation delay 2 ns min / 10 ns typ / 15 ns max (RLDIFF = 54 Ω, CL1 = CL2 = 100 pF); rise/fall 8 ns typ / 15 ns max, same load
- Receiver timing
- Propagation delay 8 ns min / 15 ns typ / 30 ns max (CL = 15 pF); skew |tPLH − tPHL| 5 ns typ
- Absolute maximum ratings
- VCC −0.3 V to +7 V; receiver inputs and driver outputs (A, B) −9 V to +14 V; receiver output −0.5 V to VCC + 0.5 V; power dissipation (8-lead SOIC) 450 mW, θJA 170 °C/W; Tstg −65 °C to +150 °C; lead temperature 300 °C (10 s)
- Package and ordering
- 8-lead SOIC_N (package option R-8); A = industrial grade, −40 °C to +85 °C; Z = RoHS-compliant; REEL7 = the tape-and-reel orderable — Rev. F prints no reel quantity or diameter
