Product details
Overview
6116SA120DB from Renesas Electronics is a 16K-bit (2K × 8) CMOS static RAM with 120ns maximum access time, TTL-compatible I/O, and military-grade reliability compliant to MIL-STD-883 Class B. It operates across –55°C to +125°C, consumes ≤50mA active current and ≤45mA standby current (TTL level), and uses a 24-pin ceramic DIP (CD24) package for high-reliability embedded control and avionics data buffering.
For engineers reviewing the 6116SA120DB datasheet, 6116SA120DB pinout, 6116SA120DB application, or 6116SA120DB equivalent, this page delivers verified timing specs, military temperature validation, DC/AC electrical parameters, pin-level functional roles, and direct alternative part guidance for legacy system sustainment and aerospace hardware refresh.
Technical Context
The 6116SA120DB implements fully static asynchronous operation-no clocks or refresh required-and features dual power modes: active read/write and TTL-level standby (CS HIGH). Its address decoder drives a 128 × 128 memory array, with input/output circuitry designed for direct TTL interfacing and low-alpha-particle soft-error susceptibility.
Control logic relies on three dedicated pins-CS, OE, and WE-with truth-table-defined modes: Standby (CS HIGH → high-Z I/O), Read (CS+OE LOW, WE HIGH), and Write (CS+WE LOW). Data retention is not supported (LA version only); this SA variant prioritizes speed and military environmental robustness over battery backup.
Key Specifications

IC Role / Device Role / Timing Role: Off-chip RAM supplementing microcontroller internal memory for ladder logic variable storage. Use Value: 120ns tAA supports scan times under 1ms; military temp range eliminates need for external cooling in enclosed cabinets. | Use Scenario: Replacement memory in discontinued automatic test equipment (ATE) platforms requiring exact form-fit-function compatibility. IC Role / Device Role / Timing Role: Drop-in SRAM replacement preserving original board layout and timing margins. Use Value: CD24 pinout matches legacy 24-pin DIP footprints; 120ns speed satisfies original design's worst-case timing budget without revalidation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 6116SA120TDB | Same speed (120ns), same military temp range, but SD24 (300-mil ceramic DIP) package | Requires PCB footprint change due to smaller body size and lead pitch | Select when board space is constrained and hermetic sealing remains mandatory |
| IS61C256AL-120MLI | 256K-bit (32K × 8), 120ns, industrial temp (–40°C to +85°C), SOIC-28 package | Higher density and surface-mount format; lacks MIL-STD-883 qualification and ceramic packaging | Choose for cost-sensitive industrial upgrades where military reliability is not required |
Compared with 6116SA120DB, 6116SA120TDB offers identical electrical and thermal performance in a physically smaller ceramic package, while IS61C256AL-120MLI provides greater capacity and modern packaging at the expense of military-grade assurance and through-hole compatibility.

FAQ
What is the maximum operating temperature range for the 6116SA120DB?
The 6116SA120DB is rated for –55°C to +125°C operation and is qualified to MIL-STD-883 Class B, making it suitable for deployment in extreme environmental conditions such as airborne, missile, and ground vehicle systems where thermal cycling and long-term reliability are critical. This specification is guaranteed across all production units.
Does the 6116SA120DB support battery backup or data retention mode?
No, the 6116SA120DB does not support battery backup or low-voltage data retention. That capability is exclusive to the LA variant (e.g., 6116LA120DB), which specifies 2V data retention voltage and microamp-level retention current. The 6116SA120DB is optimized for speed and military reliability-not ultra-low-power hold states.
What package type is used for the 6116SA120DB?
The 6116SA120DB uses a 24-pin ceramic dual in-line package (CD24) with 600-mil width. This hermetically sealed ceramic DIP provides superior moisture resistance, thermal stability, and mechanical robustness compared to plastic packages-essential for mission-critical military and aerospace applications.
Is the 6116SA120DB pin-compatible with other 6116-series variants?
Yes, all 6116SA/LA variants-including 6116SA120DB-share identical 24-pin pinouts regardless of speed grade, temperature range, or package type (CD24, SD24, PTG24, PSG24). Signal assignments (A0–A10, I/O0–I/O7, CS, OE, WE, VCC, GND) are functionally and physically consistent across the family.
What is the standby current consumption of the 6116SA120DB?
The 6116SA120DB draws a maximum of 45mA in TTL-level standby mode (ISB), defined as CS > VIH with outputs open and f = fMAX. This value is measured at VCC = 5.5V and TA = +125°C, and reflects the device's ability to reduce system power during inactive periods without entering deep-sleep states.
