SP301 Datasheet, PDF (3/18 Pages) Sipex Corporation – RS-232/RS-422 Line Drivers/Receivers

Notes:
1. In Loop-back mode
2. Only one output drive pin per package will be shorted at any time
3. From 10% to 90% of steady-state
4. This is an absolute maximum rating; normal operating levels are V < 5V
IN
5. Outputs unloaded; Inputs tied to GND; T = +25°C; V = 0V; LB=0

Typical SP302 current drains under full load are:
18mA (+12V), 10mA (-12V) and 7mA (+5V) in RS-232 mode only;
5mA (+12V), 7mA (-12V) and 56mA (+5V) in RS-422 mode only;
12mA (+12V), 14mA (-12V) and 31mA (+5V) in RS-232 and RS-422 modes;
RS-232 loads 3kΩ, 2500pF, 20kHz; RS-422 outputs across 100Ω, 500kHz.
6. In Loopback mode, the external voltage input to the receiver must not exceed ± 10V, otherwise
the loopback test may be adversely affected.
