Product details
Overview
IDT6116SA15SO from Integrated Device Technology is a 16K-bit (2K × 8) high-speed CMOS static RAM with 15 ns access time, TTL-compatible I/O, and full static operation requiring no clocks or refresh. It features chip-select–controlled standby mode, operates at 5.0 V ±10%, and is used in military-grade avionics data buffers and real-time control systems where deterministic timing and radiation-tolerant reliability are critical.
For engineers reviewing the IDT6116SA15SO datasheet, IDT6116SA15SO pinout, IDT6116SA15SO application, or IDT6116SA15SO equivalent, key selection criteria include guaranteed 15 ns tAA/tACS read access, 2V data retention capability (not applicable to SA version), industrial-temperature SOIC packaging, and MIL-STD-883 Class B compliance for harsh-environment deployment.
Technical Context
The IDT6116SA15SO implements a fully static asynchronous architecture with dual-control write enable (WE) and output enable (OE), enabling independent read/write gating. Its address decoder drives a 128 × 128 memory array, and all inputs/outputs meet TTL voltage thresholds (VIH = 2.2 V min, VIL = 0.8 V max) at 5 V supply.
Chip select (CS) directly controls power state: CS HIGH forces TTL-level standby (ISB = 40 mA max) or CMOS-level deep standby (ISB1 = 2 mA max); CS LOW enables active read/write cycles with ICC1 = 105 mA max and ICC2 = 150 mA max under dynamic load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2K × 8-bit (16,384 bits), single-port parallel SRAM |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-45ZSXI | 32K × 8 organization, 45 ns access, 3.3 V supply, 32-pin TSOP | Higher density but slower speed and different voltage domain; requires level translation | Select only if system uses 3.3 V logic and needs >16K capacity; not drop-in compatible |
| AS6C1008-55TIN | 128K × 8 organization, 55 ns access, 5 V supply, 28-pin SOJ | Larger capacity and slower timing; SOJ package incompatible with SOIC footprints | Choose for cost-sensitive volume production where 55 ns latency is acceptable and board layout allows SOJ |
Compared with IDT6116SA15SO, CY62167EV30LL-45ZSXI offers higher density but mandates 3.3 V infrastructure and introduces voltage translation complexity, while AS6C1008-55TIN provides greater capacity at lower cost but sacrifices 40 ns of timing margin and requires mechanical redesign for SOJ mounting.

FAQ
What is the maximum operating temperature range for IDT6116SA15SO?
IDT6116SA15SO is rated for commercial temperature operation from 0°C to +70°C. It is not qualified for industrial (–45°C to +85°C) or military (–55°C to +125°C) ranges - those require suffixes like "I" or "Y" in the ordering code. This specification is confirmed in the Recommended Operating Conditions table (DSC-3089/03, page 3).
Does IDT6116SA15SO support battery backup data retention?
No, IDT6116SA15SO does not support battery backup data retention. That feature is exclusive to the LA variant (e.g., IDT6116LA15SO), which specifies 2 V data retention voltage and sub-microwatt standby current. The "SA" suffix denotes standard power, and its ISB1 = 2 mA minimum confirms absence of ultra-low-retention mode.
What package type is used for IDT6116SA15SO according to the ordering information?
IDT6116SA15SO uses the 24-pin SOIC package designated "SO" in the ordering code, corresponding to the SO24-2 gull-wing variant per IDT's DSC-3089/03 datasheet (page 10). This is a 300 mil wide, surface-mount package with standard JEDEC MO-012AC dimensions and lead pitch.
Can IDT6116SA15SO be operated with a 3.3 V supply?
No, IDT6116SA15SO requires a 5.0 V ±10% supply (4.5 V to 5.5 V) as specified in DC Electrical Characteristics (Table 6, page 3). Its TTL-compatible inputs demand VIH ≥ 2.2 V and VIL ≤ 0.8 V - operation at 3.3 V violates both supply and interface specifications and risks functional failure.
Is IDT6116SA15SO pin-compatible with other 2K × 8 SRAMs like the HM6116LP-3?
IDT6116SA15SO shares the industry-standard 24-pin 2K × 8 SRAM pinout (A0–A10, I/O0–I/O7, CS, WE, OE, VCC, GND), matching HM6116LP-3 and most JEDEC-compliant variants. However, timing parameters differ: HM6116LP-3 has 300 ns access, so while physical layout may reuse footprints, timing-critical designs require validation of tAA, tACS, and tWC margins.
