LM55325/LM75325 memory drivers general description
The LM55325 and LM75325 are monolithic memory drivers which feature high current outputs as well as Internal decoding of logic Inputs These CirCUits are designed for use with magnetic memOries
The CirCUit contains two 600 mA sink-switch pails and two 600 mA source-switch pall s Inputs A and B determine source selection while the source strobe (S,) allows the selected source turn on In the same manner, tnputs C and D determine Sink selection while the sink strobe (S2) allows the selected sink turn on
operate at higher source CUI rents fOI a given lunctlon temperature If thiS method of source current setting IS not desll ed, then Nodes Rand
R'NT can be shorted externally activating an Internal reSistor connected from V CC2 to Node R ThiS pi oVldes adequate base drive for source currents up to 375 mA with V CC2 ~ 15V or 600 mA with V CC2 ~ 24V
The LM55325 operates 0 aveI the }ull military temperature range of -55 e.
