Digital Chroma Delay Line<br />

MC44140P, ow Case 648, 751G<br />

The MC44140 is a monolithic 64 J.LS delay line, intended for<br />

color TV applications. It may be used as a baseband chroma<br />

correction circuit (with PAL), or as a chroma delay line (with<br />

SECAM). The device has been designed for use with the<br />

MC44000 as part of Chroma 4, or with the MC44011 , but may<br />

also be used as a general purpose delay line for other<br />

applications.<br />
