TA1318N
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA1318N
SYNC Processor, Frequency Counter IC for TV Component Signals
TA1318N is a sync processor for TV component signals.
TA1318N provides sync and frequency counter processing for
external input signals.
These functions are integrated in a 24 pin dual-in-line
shrink-type plastic package.
TA1318N provides I
2
C bus interface, so various functions and
controls are adjustable via the bus.
