The device consists of eight npn Darlington pairsthat feature high-voltage outputs with common-cathode clampdiodes for switching inductive loads. The collector-current rating ofeach Darlington pair is 500 mA. The Darlington pairs may beconnected in parallel for higher current include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), linedrivers, and logic buffers.
The device consists of eight npn Darlington pairs ... low- to high-level output VS = 50 V, RL = 163 Ω, 130 ns ... Figure 5. hFE, VCE(sat) Test Circuit Open VCE II IC hFE = IC II Figure 6. IR Test Circuit VR Open IR SLRS049C − FEBRUARY1997 − REVISED AUGUST 2004
