The explanations of integrated circuits designations

Our company uses two types of integrated circuits designations, which are represented on this webpage.

The description of this classification is given below:

Part ID format: aRDddddA/BCD,   example: aRD101/C5B

Where:

αRD – company sign

dddd – arbitrary  amount of numbers corresponding to equivalent part or our product line series

A –  part group (if group exists), can be any letter

B – part form type  (packaged IC, unpackaged IC or IC on polyimide carrier)

For package IC’s:

A – CDIP-8

B – CDIP-14

C – TO-5

H – TO-8

N – 14-Lead Metal-Ceramic

P or T – 16-Lead Flat Metal-Ceramic

U – 16-Lead Quad Metal-Ceramic

Z – CQCC2-N20-K4

For unpackaged IC’s:

W – wafer

D – die form

K – chip on carrier 

L – chip on polyimide carrier

C - acceptance level 

D – temperature range, °С:

М – (-25;85)                        C – (-60;85)

D – (-45;85)                         B – (-60;125)             

L – (-45;100)                       E – (-60; 100)

R – (-45;125)
