description
Series SN75471 dual peripheral drivers are functionally interchangeable with series SN75451B and series
SN75461 peripheral drivers, but are designed for use in systems that require higher breakdown voltages than
either of those series can provide at the expense of slightly slower switching speeds than series 75451B (limits
are the same as series SN75461). Typical applications include high-speed logic buffers, power drivers, relay
drivers, lamp drivers, MOS drivers, line drivers, and memory drivers.
The SN75471, SN75472, and SN75473 are dual peripheral AND, NAND, and OR drivers, respectively,
(assuming positive logic), with the output of the logic gates internally connected to the bases of the npn output
transistors.
Series SN75471 drivers are characterized for operation from 0°C to 70°C.
