DS3245 Quad MOS Clock Driver
General Description
The DS3245 is a quad bipolar-to-MOS clock driver with TTL
compatible inputs. It is designed to provide high output cur-
rent and voltage capabilities necessary for optimum driving
of high capacitance N-channel MOS memory systems.
Only 2 supplies, 5 V
DC
and 12 V
DC
, are required without
compromising the usual high V
OH
specification obtained by
circuits using a third supply.
The device features 2 common enable inputs, a refresh in-
put, and a clock control input for simplified system designs.
The circuit was designed for driving highly capacitive loads
at high speeds and uses Schottky-clamped transistors. PNP
transistors are used on all inputs, thereby minimizing input
loading.
