Supported chips

Chip Hippo ships 116 chips, every one with a datasheet-accurate pinout and a working simulation you can wire up and run — logic from two families, 74LS TTL and CD4000 CMOS, listed 74LS first in each table. 102 of them carry a built-in example circuit, marked below: open the chip's Pin Assignment window and click its example button to drop a working bench onto a new desktop. The memory, interface and processor chips have none — a RAM or a CPU can't be shown off by flipping switches at it.

How each part behaves on the desk — open-collector outputs, non-standard power pins, how the CPUs are clocked — is covered in The Chip Library. LEDs, switches, displays and the other discrete parts are in Chips & Components.
