1 Features and Benefits Up to 9 ma constant-current outputs Undervoltage lockout Low-power CMOS logic and latches High data input rate Functional replacement for TB6276BN/BF Packages Not to scale 24-pin DIP (A package) 24-pin SOICW (LW package) Description The A6276 is specifically designed for LED-display applications. Each BiCMOS device includes a 16-bit CMOS shift register, accompanying data latches, and 16 NPN constantcurrent sink drivers. Except for package style and allowable package power dissipation, the device options are identical. The CMOS shift register and latches allow direct interfacing with microprocessor-based systems. With a 5 V logic supply, typical serial data-input rates are up to 2 MHz. The LED drive current is de ter mined by the user selection of a single resistor. A CMOS serial data output permits cascaded connections in applications requiring additional drive lines. For inter-digit blanking, all output drivers can be disabled with an ENABLE input high. Similar 8-bit devices are available as the A6275. Two package styles are provided: through-hole DIP (suffix A) and surface-mount SOIC (suffix LW). In normal applications, the copper leadframe and low logic-power dissipation of the DIP allow it to sink maximum rated current through all outputs con tin u ous ly over the operating temperature range (9 ma,.75 V drop, 85 C). Both packages are lead (Pb) free, with % matte tin leadframe plating. Functional Block Diagram I

Clock Transition Time, t r or t f... 1 μs Serial data present at the input is transferred to the shift register on the logic -to-logic 1 transition of the CLOCK input pulse. On succeeding CLOCK pulses, the registers shift data information towards the SERIAL DATA OUTPUT. The serial data must appear at the input prior to the rising edge of the CLOCK input waveform. Information present at any register is transferred to the respective latch when the LATCH ENABLE is high (serial-topar al lel con ver sion). The latches continue to accept new data as long as the LATCH ENABLE is held high. Ap pli ca tions where the latches are bypassed (LATCH ENABLE tied high) will require that the OUTPUT EN ABLE input be high during serial data entry. When the OUTPUT ENABLE input is high, the output sink driv ers are disabled (OFF). The in for ma tion stored in the latches is not affected by the OUTPUT ENABLE input. With the OUT- PUT ENABLE input low, the outputs are con trolled by the state of their re spec tive latches. 7

10 Applications Information The load current per bit (I O ) is set by the external re sis tor (R EXT ) as shown in the figure below k 2 k 3 k CURRENT-CONTROL RESISTANCE, R V CE =.7 V EXT IN OHMS 5 k Dwg. GP-61 Package Power Dissipation (P D ). The maximum allow able package power dissipation is determined as P D (max) = (15 - T A )/R JA. The actual package power dissipation is P D (act) = DC (V CE I O 16) + (V DD I DD ), where DC is the duty cycle. When the load supply voltage is greater than 3 V to 5 V, considering the package power dissipating limits of these devices, or if P D (act) > P D (max), an external voltage reducer (V DROP ) should be used. diode (V Z ), or a series string of diodes (approximately.7 V per diode) for a group of drivers. If the available voltage source will cause unacceptable dissipation and series resistors or diode(s) are undesirable, a regulator such as the Sanken Series SAI or Series SI can be used to pro vide supply voltages as low as 3.3 V. For reference, typical LED forward voltages are: White V Blue V Green V Yellow V Amber V Red V Infrared V Pattern Layout. This device has a common logic-ground and power-ground terminal. If ground pattern layout con tains large common-mode resistance, and the voltage between the system ground and the LATCH ENABLE or CLOCK terminals ex ceeds 2.5 V (because of switching noise), these devices may not operate correctly. V LED V DROP Load Supply Voltage (V LED ). These devices are designed to operate with driver voltage drops (V CE ) of.4 V to.7 V with LED forward voltages (V F ) of 1.2 V to 4. V. If higher voltages are dropped across the driver, package power dissipation will be increased significantly. To minimize package power dissipation, it is rec om - mend ed to use the lowest possible load supply voltage or to set any series dropping voltage (V DROP ) as V DROP = V LED - V F - V CE with V DROP = I o R DROP for a single driver, or a Zener V F V CE Dwg.
