Description
The ROB74 is an operational amplifier with JFET inputs, an analog integrated circuit listed in the Agenda radioelectronistului (2nd edition, 1989) among the integrated circuits made in Romania by ICCE (CCSIT-CE), in TO-116, TO-99 and MP-48 packages [1]. Its pinout is in the Gallery.
Coded as (Romanian system, internal CCSIT-CE code) [2]:
| Part | Meaning |
|---|---|
| RO | manufacturer’s code: RO (Romania) |
| B | bipolar integrated circuit |
| 74 | identification number |
The Agenda radioelectronistului (2nd edition, 1989) gives the parameters of the ROB74 in the table of operational amplifiers and voltage comparators made in Romania by IPRS Băneasa and CCSIT-CE (section 35.3) [3]: absolute maximum ratings and electrical characteristics over the full temperature range; they are in the specifications.
Notes on the table of section 35.3 [3]: Values printed with „<” (maximum) or „>” (minimum) are given here without the sign: „<” for IIB and IS. VIO and IIO read „<130” and „<0.3” or „<190” and „<0.9” (the digit is damaged in the scan) and are left out. Ri and AV are printed as powers of ten whose exponents are unclear in the scan, and are left out.
