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.
