Description
The Sn75476 Through Sn75478 Are Dual Peripheral Drivers Designed For Use In Systems That Require
High Current, High Voltage, And Fast Switching Times. The Sn75476, Sn75477, And Sn75478 Provide And,
Nand, And Or Drivers Respectively. These Devices Have Diode-clamped Inputs As Well As High-current,
high-voltage clamp diodes on the outputs for inductive transient protection.
The Sn75476, Sn75477, And Sn75478 Drivers Are Characterized For Operation From 0 C To 70 C.
