Description
The MMC4021 is a CMOS logic integrated circuit of the 4000 series, an 8-bit static shift register with synchronous serial (or asynchronous parallel) inputs and serial output, listed in the Agenda radioelectronistului (2nd edition, 1989) among the logic integrated circuits made in Romania by Microelectronica [1]. Its pinout is in the Gallery.
Coded as (code of Întreprinderea Microelectronica for logic integrated circuits) [2]:
| Part | Meaning |
|---|---|
| M | characteristic prefix of Întreprinderea Microelectronica |
| MC | technology: CMOS (MC = CMOS, MN = NMOS, MP = PMOS) |
| 4 | circuit series: 4 = series 4XXX(X) (CMOS) |
| 021 | circuit type (serial number of 3–4 digits) |
| –E, –F, –G, –H | DIL package and operating temperature range (series 4XXX(X)): E = plastic (−40…+85 °C), F = ceramic „frit seal” (−40…+85 °C), G = multilayer ceramic (−55…+125 °C), H = ceramic „frit seal” (−55…+125 °C); the letter is not printed in the panels |
