Description

The ROB311 is a precision voltage comparator, 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
311 identification number

The Agenda radioelectronistului (2nd edition, 1989) gives the parameters of the ROB311 in the table of operational amplifiers and voltage comparators made in Romania by IPRS Băneasa and CCSIT-CE, among the voltage comparators (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 VIO, IIO and IIB. The response time is measured with VI = 100 mV and a 5 mV overdrive.
