Introduction

The Intel 3232 contains an address multiplexer and refresh counter for multiplexed address dynamic RAMs requiring refresh of up to 6 input addresses (or 4K bits for 64 x 64 organization). It multiplexes twelve bits of system supplied address to six output address pins. The device also contains a 6 bit refresh counter which is externally controlled so that either distributed or burst refresh may be used. The high performance of the 3232 makes it especially suitable for use with high speed N - channel RAMs like the 2104A. The 3232 operates from a single +5 volt power supply and is specified for operation over a 0 to +75°C ambient temperature range.
