DS8187 Datasheet | National Semiconductor

Description The DS8187 is a vacuum fluorescent display tube driver This device is implemented in CMOS technology to provide high voltage output drivers and low power Dimming may be acplished by either analog or digital input Autoload capability is acplished by connecting the DATA OUT pin to the LOAD ENABLE input pin with the addition of a start bit to the input data stream Features Y Y Y Y Y 33 Segment Direct Drive 25 b 0 8 m A and 8 b 2 m A output drivers 49 steps of dimming mask programmable Analog or digital input dimming control DATA OUT pin for cascading Mask options allow reconfiguring of outputs with respect to shift register bit position Autoload or external load capability Block Diagram TL F 11220 - 4 FIGURE 1 C1995 National Semiconductor Corporation TL F 11220 RRD-B30M105 Printed in U S A Absolute Maximum Ratings If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications b 0 3 to a 20V Supply Volltage (VCC) b 0 3 to VCC a 0 3V DC Input Voltage (VIN) DC Output Voltage (VOUT) .. b 65 to a 150 C Storage Temperature Range Lead Temperature (Soldering 10 sec ) 260 C Power Dissipation (PD) at 25 C DIP Board Mount DIP Socket Mount Typical Values i JA DIP Board Mount i JA DIP Socket Mount TBD TBD TBD C W TBD C W Operating Conditions Supply Voltage (VCC) DC Input or Output Voltage Temperature Range Electro-Static Discharge (ESD) Min 8 0 b 40 Max 18 VCC a 85 2K Unit V V C V DC Electrical Characteristics VCC e 8V to 18V All voltages referenced to GND unless otherwise specified Symbol VIH VIL IIH1 IIH2 IIH3 IIL1 IIL2 IIL3 ILI VOH1 VOH2 VOH3 VOL1 Parameter High Level Input Voltage Low Level Input Voltage High Level Input Current (Clock Data In Load VK) High Level Input Current (Blank) High Level Input Current (TEST2) Low Level Input Current (Clock Data In Load VK) Low Level Input Current (BLANK IN) Low Level Input Current (TEST2) Input Leak Current (VD) High...
