ICM7555_1

• The format of this data sheet has been redesigned to comply with the new identity guidelines of NXP

Semiconductors.

• Legal texts have been adapted to the new company name where appropriate.

• Provided separate pinning diagrams for SO8 and DIP8 packages (Figure 2 and Figure 3,

respectively).

• Added Table 2 “Pin description”.

• Table 4 “Limiting values”:

– Symbols VTRIG, VCV, VTH, VRST are replaced with VI (specific pin names are now noted under

Conditions column).

– Symbol/parameter “PDMAX, maximum power dissipation” replaced with “P, power dissipation” (only

maximum values given).

– Symbol/parameter “TSTG, storage temperature range” replaced with “Tstg, storage temperature”.

– Symbol changed from “TSOLD” to “Tsp, solder point temperature”

• Table 5 “Characteristics”:

– Symbols ∆f/f, ∆f/∆V, ∆f/∆T, have been added for Astable mode timing.

– Symbols VTRIG, VCV, VTH, VRST are replaced with VI (specific pin names are now noted under

Conditions column).

– Symbols ITRIG, ITH, IRST are replaced with II (specific pin names are now noted under Conditions

column).

– Symbol/parameter “VDIS, discharge output voltage” changed to “Vo, output voltage” (specific pin

name is now noted under Conditions column).

– Symbol/parameter “tR, rise time of output” changed to “tr(o), output rise time”.

– Symbol/parameter “tF, fall time of output” changed to “tf(o), output fall time”.

– Symbol “FMAX” changed to “fosc, oscillator frequency”.

• Section 11.4 “Astable operation”: changed symbol for duty cycle from “D” to “δ”.

• Added Section 12 “Package outline”.

• Added soldering information.

• Added Section 15 “Abbreviations”.
