The RCA-MWS5101 is a 256-word by 4-bit static random-
access memory designed for use In memory systems where
high speed, very low operating current, and simplicity in
use are desirable. It has separate data inputs and outputs
and utilizes a single power supply of 4 to 6.5 volts.
Two Chir·Select inputs are provided to simplify system
expansion. An Output Disable control provides Wire-OR
capability and is also useful in common Input/Output
systems by forcing the output into a high-impedance state
during a write operation independent of the Chip-Select
input condition. The output assumes a high-impedance
state when the Output Disable is at high level or when the
chip is deselected by CS1 and/or CS2.
The high noise immunity of the CMOS technology is
preserved in this design. For TTL interfacing at 5-V
operation, excellent system noise margin is preserved by
using an external pull-up resistor at each input.
For Rpplications requiring wider temperature and operating
voltage ranges, the mechanically and functionally equivalent
static RAM, RCA-CDP1822, may be used
The MWS5101 types are supplied in 22-lead hermetic dual-
in-line, side-brazed ceramic packages (0 suffix), in 22-lead
dual-in-line plastic packages (E suffix), and in chip form (H
suffix).
