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
