UDN2987A-6

www.DataSheet4U.com UDN2987x-6 DABIC-5 8-Channel Source Driver with Overcurrent Protection Package A, 20-pin DIP Package LW, 20-pin SOIC-W Approximate Scale 1:1 Providing overcurrent protection for each of its eight sourcing outputs, the UDN2987A-6 and UDN2987LW-6 drivers are used as an interface between standard low-level logic and relays, motors, solenoids, LEDs, and incandescent lamps. These devices include thermal shut down and output transient protection/clamp diodes for use with sustaining voltages to 35 V. Features 4.75 to 35 V driver supply voltage Output enable-disable (OE/R) 350 mA output source current Overcurrent protected Internal ground clamp diodes Output Breakdown Voltage 35 V minimum TTL, DTL, PMOS, or CMOS compatible inputs Internal Thermal Shut Down (TSD) In these drivers, each channel includes a latch to turn off that channel if the maximum channel current is exceeded. All channels are disabled if the thermal shutdown is activated. A common FAULT output is used to indicate either chip thermal shutdown or any overcurrent condition. All outputs are enabled ¯ is low, DataShee by pulling the common OE/R input high. When OE/R all outputs are inhibited and the eight latches are reset. The DataSheet4U.com ¯ function can be especially important during power-up, in OE/R preventing floating inputs from turning on the outputs. Under normal operating conditions, each of eight outputs will source in excess of 100 mA continuously at an ambient temperature of 25°C ...
