ideally suited for interfacing between low-level logic circuitry and multiple peripheral power loads, the series LR2001A/l high-voltage, high-current darlington arrays feature continuous load current ratings to 500 ma for each of the seven drivers. at an appropriate duty cycle depending on ambient temperature and number of drivers turned on simultaneously, typical power loads totaling over 120 w (350 ma x 7, 50 v) can be controlled. typical loads include relays, solenoids, stepping motors, magnetic print hammers, multiplexed led and incandescent displays, and heaters. all devices feature open-collector outputs with integral clamp diodes. the LR2001A/l have series input resistors selected for operation directly with dtl ttl pmos or cmos. these devices will handle numerous interface needs - particularly those beyond the capabilities of standard logic buffers. the LR2001A/l are the standard darlington array. the outputs are capable of sinking 500 ma and will withstand at least 50v in the off state.outputs may be paralleled for higher load current capability. these darlington arrays are furnished in 16-pin dual in-line plastic packages (suffix ?? and 16-lead surface-mountable soics (suffix ??. all devices are pinned with outputs opposite inputs to facilitate ease of circuit board layout. all devices are rated for operation over the temperature range of -40 c to +85 c. features ttl, dtl, pmos, or cmos-compatible inputs output current to 500 ma output voltage to 50 v transient-protected outputs dual in-line plastic package or small-outline ic package high-voltage, high-current darlington arrays 16 15 14 13 12 611 710 89 1 2 3 4 5 note that the LR2001A series (dual in-line package) and lr2001l series (small-outline ic package) are electrically identical and share a common terminal number assignment. absolute maximum ratings output voltage, v ce 50 v input voltage, v in ................................ 30 v continuous output current, i c ................................................. 500 ma continuous input current, i in ........... 25 ma power dissipation, p d (one darlington pair) ..................... 1.0 w (total package) ....................... see graph operating temperature range, t a .................................. -40 c to +85 c storage temperature range, t s ................................. -55 c to +150 c leshan radio comp any , ltd.
