DESCRIPTION
The TK15420M is a vidoe line driver IC which contains 2
channels. It is an operational amplifier type and the
voltage gain is adjustable with an external resistor.
It is suitable for replacement of Motorola’s video line driver
IC MC14577CF.
The TK15420M is available in the SOP-8 surface mount
package.
