M54914FP

The M54914FP is a Bi-CMOS semiconductor integrated circuit consisting of an F2F demodulator for magnetic stripocard readers.The data signal read from a magnetic stripe card by a magnetic head is applled to HD-1 and HD-2.Outputs CLS,RCP and RDD are changed from lowactive to high-active when INV is set low.

Features of the M54914FP are:(1)low power dissipation(standby current 1mA typ));(2)ignore bit select input(bits 4,8,16);(3)output polarity(low-active,high-active)selector input;(4)compact mini-molded package;(5)wide operating temperature range(Ta=-20 to +75).

The absolute maximum ratings of the M54914FP can be summarized as:(1):the symbol is VCC,the parameter is supply voltage,the rating is -0.3 to +7.0,the unit is V;(2):the symbol is VI,the parameter is input voltage,the rating is -0.3 to VCC+0.3,the unit is V;(3):the symbol is VO,the parameter is output voltage,the rating is -0.3 to VCC+0.3,the unit is mA;(4):the symbol is II,the parameter is input current,the rating is -10 to +10,the unit is mA;(5):the symbol is IO,the parameter is output current,the rating is -10 to +10,the unit is mA;(6):the symbol is VID,the parameter is differential input voltage,the rating is -0.6 to +0.6,the unit is V;(7):the symbol is Topr,the parameter is operating temperature,the rating is -20 to +75,the unit is ;(8):the symbol is Tstg,the parameter is storage temperature,the rating is -55 to +125,the unit is .
