LB1273R

Ordering number:ENN667B Monolithic Digital IC LB1273R 6-Unit, Darlington Transistor Array Overview The circuit construction of this IC is a Darlington transistor array with six units, most suitable for printer hammer drive, lamp, and relay drive. With built-in protective diodes against negative inputs, it is advantageous in designing drive circuits for printer calculators and cash registers. Package Dimensions unit:mm 3004A-DIP14TD [LB1273R] 14 Features Since six units are included, it is suitable for 18-digit printers. The load current is considerably large i. e., 230mA and is, thus, suitable for thermal printers. 1 2.0 19.0 6.0 0.5min 3.46 7.62 3.5 4.26max 6.45 0.4 Specifications Absolute Maximum Ratings at Ta = 25˚C Parameter Output supply voltage Input supply voltage Output inflow current Instantaneous output inflow current GND pin inflow current GND pin instantaneous outflow current Allowable power dissipation Symbol VOUT VIN IOUT iop I7 I7p Pd max Instantaneous allowable power dissipation Junction temperature Operating temperature Storage temperature Tj Topr Tstg 1.8 2.54 0.5 1.3 Conditions per unit per unit duty=60%, pulse width<2ms duty=60%, pulse width<2ms Pulse width must be less than 2ms.
