DESCRIPTION
In order to enhance PC board layout, the AC541 offers a pinout having inputs and outputs on opposite sides of the package. The device is designed to interface directly High Speed CMOS systems with TTL, NMOS and CMOS output voltage levels. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
