Description
The Intersil ACS20MS is a radiation hardened dual 4-input
NAND gate. A low on any input forces the output to a high logic
state.
The ACS20MS utilizes advanced CMOS/SOS technology to
achieve high-speed operation. This device is a member of the
radiation hardened, high-speed, CMOS/SOS Logic Family.
