CDP1833C Datasheet | Intersil

Description The CDP1883 is a CMOS 7-bit memory latch and decoder circuit intended for use in CDP1800-series microprocessor systems. It can serve as a direct interface between the multiplexed address bus of this system and up to four 8K x 8-bit memories to implement a 32K-byte memory system. With four 4K x 8-bit memories, a 16K-byte system can be decoded. The device is also patible with non-multiplexed address bus microprocessors. By connecting the clock input to VDD, the latches are in the data-following mode and the decoded outputs can be used in general-purpose memory-system applications. The CDP1833 is patible with CDP1800-series microprocessors operating at maximum clock frequency. The CDP1883 and CDP1883C are functionally identical. They differ in that the CDP1883 has a remended operating voltage range of 4V to 10.5V and the C version has a remended operating voltage range of 4V to 6.5V. The CDP1883 and CDP1883C are supplied in 20 lead dualin-line plastic packages (E Suffix).
