Standard ICs
7-channel Darlington transistor array
BA6250 / BA6250F / BA6251 / BA6251F
The BA6250, BA6250F, BA6251, and BA6251F are 7-channel transistor arrays particularly suitable for interfaces
between a microcomputer in a VCR and the various ICs, or between one IC and another, and for low current drives
such as LEDs.
