Read-Only Memories (ROMs)
CDP1834, CDP1834C
1028-Word X 8-Bit Static
Read-Only Memory
Features:
• Industry pin compatible
• Three-state outputs
The RCA-CDP1834 and CDP1834C are 8192-bit mask-
programmable CMOS read-only memories organized as
1024-words x 8-bits and designed for use in CDP1800-
series microprocessor systems. The CDP1834-senes ROM's
are completely static; no clocks are required
Two Chip-Select inputs (CS1, CS2) are provided for memory
expansion. The polarity of each Chip-Select is user mask-
programmable. The CDP1834-series is pin-compatible with
industry type 2708 EPROM. The CDP1834C is functionally
identical to the CDP1834. The CDP1834 has a recommended
operating voltage range of 4 to 10.5 volts and the CDP1834C
has a recommended operating voltage range of 4 to 6.5
volts. The CDP1834 and the CDP1834C are supplied in
24-lead dual-in-line ceramic packages (D suffix) and in
24-lead dual-in-line plastic packages (E suffix). The
CDP1834C is also available in chip form (H suffix).
