Description
The H431 is a voltage-to-frequency converter, a hybrid integrated circuit made in Romania by ICCE (CCSIT-CE) and listed in the Agenda radioelectronistului (2nd edition, 1989) in group 4.3 „Convertoare U/f și f/U” (voltage-to-frequency and frequency-to-voltage converters) of the family „Circuite de conversie a datelor” (data conversion circuits) [1]. Its codes (H431 and H431C) are in the Variants table.
The table describes it as „Convertor tensiune/frecvență” [1].
The code is printed „H 431 (C)”; it is read here as two codes, H431 and H431C, because the 1st edition of the Agenda (1983) writes the „H 821 (R)” of this table as „H821; H 821 R” [2]. The book does not say how the two versions differ.
The 1st edition (1983) lists only the H 431, without the C, with the same description, among the hybrid integrated circuits of I.C.C.E. [2].
The table gives no parameters or drawing. In it, the first two digits of every code repeat the numbers of its family and group (here 4.3) [1].
