CMOS 2048-Word by 8-Bit
Static RAM
Features:
• Fully static operation
• Single power supply: 4.5 Vt05.5 V
• All inputs and outputs directly TTL compatible
• 3-state outputs
• Industry standard 24-pin configuration
• Chip-enable gates address buffers for minimum standby current
• Data retention voltage: 2 V min.
The RCA-COM6116A Is a CMOS 2048-word by 8-bit static
random-access memory. It is designed for use in memory
systems where high-speed, low power and simplicity In use
are desirable. This device has common data inputs and data
outputs and utilizes aslngle power supply of 4.5 V to 5.5 V. A
chip-enable Input and an output-enable input are provided
for memory expansion and output buffer control.
The chip enable (CE) gates the address and output buffers
and powers down the chip to the low power standby mode.
The output enable (CE) controls the output buffers to
eliminate bus contention.
The COM6116A-2 and COM6116A-3 are supplied in a 24-
lead dual-In-line plastic package (E suffix). The COM-
6116A-9lssupplied in a 24-lead dual-in-line plastic package
(E suffix) and a 24-lead dual-in-line side-brazed ceramic
package (0 suffix).

OPERATING CONDITIONS at TA = 0 to +70·C, (CDM6116A-2, CDM6116A-3); TA = _40° to +85°C (CDM6116A-9)
For maximum reliability, operating conditions should be lelected so that operation Is always within the following ranges:
