LM55325
LM55325 is memory drivers manufactured by National Semiconductor.
description
The LM55325 and LM75325 are monolithic memory drivers which feature high current outputs as well as Internal decoding of logic Inputs These Cir CUits are designed for use with magnetic mem Ories
The Cir CUit contains two 600 m A sink-switch pails and two 600 m A 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 f OI a given lunctlon temperature If thi S method of source current setting IS not desll ed, then Nodes Rand
R'NT can be shorted externally activating an Internal re Sistor connected from V CC2 to Node R Thi S pi o Vldes adequate base drive for source currents up to 375 m A with V CC2 ~ 15V or 600 m A with V CC2 ~ 24V
The LM55325 operates 0 ave I the }ull military temperature range of -55...
