TD62708N

TD62708N TOSHIBA BIPOLAR DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC TD62708N 8CH HIGH CURRENT SOURCE DRIVER The TD62708N is comprised of eight source current output stages and ENABLE inputs which can gate the outputs. TD62708N features a large output source current of 1.8 A and minimized output voltage change vs output current change. These features make the device optimum for driving the matrix of ink jet printer print heads, LEDs, and the scan side of resistor matrixes. Before using this device, note the thermal conditions for usage. FEATURES Input terminal : High active Enable terminal : Low input output active mode Output current : IOUT = 1.8 A (MAX) A little change of output voltage : ∆VOH1 ≤ 0.45 V (at IOH = 0.18 A~1.44 A) Package type : DIP24N Input compatible with TTL, 5 V CMOS Weight: 1.2 g (typ.)

For applications whose thermal conditions are more demanding, TOSHIBA recommends an external resistor (REXT : approx. 0.9 Ω / 2W) be connected between VCC2 and VC. * 2: When connecting an external resistor between BVCC2 and VC, to avoid parasitic sub currents, set the voltage between VC and OUT as 0.3 V or more. Set the external resistor value so that the voltage between VC and OUT is 0.3 V or more at the maximum temperature of the operating temperature range. INPUT CIRCUIT : IN, ENABLE...
