Description
Equivalent
7490 (20011A date code) is just a standard 74LS90 BCD decade‐counter. Direct equivalents include:
• SN54/74LS90 (TTL)
• SN74HC90 or CD74HC90 (HC-CMOS)
• SN74HCT90 or MC74HCT90A (HCT-CMOS)
• DM74LS90 (various vendors)
• Nexperia 74HC390 (dual counter, one half used)
All share identical pinouts, timing and logic behavior.
