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 compatible with non-multiplexed address
bus microprocessors. By connecting the clock input to V
the latches are in the data-following mode and the decoded
outputs can be used in general-purpose memory-system
applications.

The CDP1833 is compatible with CDP1800-series micropro­cessors operating at maximum clock frequency.

The CDP1883 and CDP1883C are functionally identical.
They differ in that the CDP1883 has a recommended operat­ing voltage range of 4V to 10.5V and the C version has a
recommended operating voltage range of 4V to 6.5V.

The CDP1883 and CDP1883C are supplied in 20 lead dual­in-line plastic packages (E Suffix).
