It consists of a ROM | It consists of a a 12×10×4 ROM coupled to a 4-bit DAC with internal precision current sources requiring a single precision external reference. | ||
The ten "memory positions" are scanned by a 4-bit BCD input which may be 0 to -15 V timeslot data or T levels or any combination thereof. | |||
* [[ | Intended applications are for encoding of CRT readout directly with electrically alterable information. | ||
The base chip is customized for instrument-specific ROM content by metallization layer mask changes. | |||
See the individual "programmed" chips for instrument usage: [[155-0086-00]], [[155-0087-00]], [[155-0088-00]], [[155-0104-00]], [[155-0105-00]], [[155-0110-00]], and [[155-0135-00]]. | |||
