Product details
Overview
6116LA120DB from Renesas Electronics is a 16K-bit (2K × 8) low-power CMOS static RAM with 120ns maximum access time, TTL-compatible I/O, and military-grade (-55°C to +125°C) operation in a 24-pin ceramic DIP (CD24) package. It supports battery backup data retention at 2V and delivers standby current as low as 0.1mA under CMOS-level chip select.
For engineers reviewing the 6116LA120DB datasheet, 6116LA120DB pinout, 6116LA120DB application, or 6116LA120DB equivalent, this device is selected for high-reliability embedded systems requiring non-refreshed memory, extended temperature operation, and ultra-low standby power in legacy military avionics, industrial controllers, and space-constrained instrumentation.
Technical Context
This SRAM uses fully static asynchronous architecture-no clocks or refresh cycles required-and features dual standby modes: TTL-level (ISB = 40mA max) and CMOS-level (ISB1 = 0.1mA typ) for system-level power optimization. Its address/data bus is directly TTL-compatible, eliminating level-shifting needs in mixed-logic designs.
The device implements a 128 × 128 memory array with integrated address decoder, I/O control, and input data circuitry. Data retention at 2V (LA version only) enables seamless battery backup during main power loss, validated across full military temperature range without external support circuitry.

FAQ
What is the maximum operating temperature range for the 6116LA120DB?
The 6116LA120DB is rated for -55°C to +125°C operation and is manufactured in compliance with MIL-STD-883, Class B. This full military temperature range is confirmed in the Absolute Maximum Ratings table and supported by characterization across all electrical parameters-including access time, standby current, and data retention-at both extremes.
Does the 6116LA120DB support true data retention at 2V, and under what conditions?
Yes, the 6116LA120DB supports guaranteed data retention at 2.0V (VDR = 2.0V min), as specified in the Data Retention Characteristics table. This applies only to LA versions, requires CS > VHC, and is validated over the full -55°C to +125°C range with ICCDR ≤ 0.5µA (typical) at 2.0V.
What package type is used for the 6116LA120DB, and is it hermetically sealed?
The 6116LA120DB uses a 24-pin ceramic dual in-line package (CD24, 600-mil width), explicitly listed in the Ordering Information table. Ceramic DIP packages are inherently hermetically sealed, satisfying MIL-STD-883 requirements for moisture resistance and long-term reliability in harsh environments.
Can the 6116LA120DB be interfaced directly with 5V TTL logic without level shifters?
Yes, the 6116LA120DB features fully TTL-compatible inputs and outputs: VIH = 2.2V min, VIL = 0.8V max, VOH ≥ 2.4V at -4mA, and VOL ≤ 0.4V at 8mA. These values meet standard 5V TTL specifications, enabling direct connection to legacy microcontrollers, FPGAs, and peripheral ICs.
How does the standby power consumption of the 6116LA120DB compare between TTL-level and CMOS-level chip select?
The 6116LA120DB offers two standby modes: ISB = 40mA max (TTL-level CS > VIH) and ISB1 = 0.1mA typical (CMOS-level CS > VHC). The latter reduces power by >99% versus active operation (ICC1 = 85mA max), making it ideal for battery-backed systems where ultra-low quiescent current is mandatory.
