DS1651/DS3651
Quad High Speed MOS Sense Amplifiers
General Description
The DS1651/DS3651 is TTL compatible high speed circuits
intended for sensing in a broad range of MOS memory sys-
tem applications. Switching speeds have been enhanced
over conventional sense amplifiers by application of Schot-
tky technology, and TRI-STATE^® strobing is incorporated, of-
fering a high impedance output state for bused organization.
The DS1651/DS3651 has active pull-up outputs and offers
open collector outputs providing implied “AND” operations.
