Product details
Overview
IDT6116SA20SOI from Integrated Device Technology is a 16K-bit (2K × 8) high-speed CMOS static RAM with 20 ns maximum access time, TTL-compatible I/O, and industrial temperature range (–45°C to +85°C). It operates at 5.0 V ±10%, supports full static asynchronous operation with no refresh required, and features dual standby modes - TTL-level (40 mA) and CMOS-level (2 mA) - for power-sensitive embedded control and data buffering applications.
For engineers reviewing the IDT6116SA20SOI datasheet, IDT6116SA20SOI pinout, IDT6116SA20SOI application, or IDT6116SA20SOI equivalent, key selection considerations include its 24-pin SOIC package, 2K × 8 organization, guaranteed 20 ns read cycle time across industrial temperatures, and compatibility with legacy 5 V TTL bus systems in avionics, test equipment, and industrial PLCs.
Technical Context
The IDT6116SA20SOI implements a fully static asynchronous memory architecture with independent chip select (CS), output enable (OE), and write enable (WE) controls, enabling flexible read/write timing without clocks or refresh cycles. 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) for direct interfacing with 5 V logic families.
Two distinct standby modes are supported: TTL-level standby (ISB = 40 mA max) activates when CS > VIH, while CMOS-level standby (ISB1 = 2 mA max) engages when CS > VHC and input pins are held at valid logic levels. This dual-mode design enables system-level power optimization in battery-backed or thermally constrained environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2K × 8-bit (16,384 bits), single-port SRAM with byte-wide data interface |
| Access Time (tAA) | 20 ns max at VCC = 4.5–5.5 V, TA = –45°C to +85°C - guarantees deterministic read latency in real-time control loops |

| Standby Current (ISB1) | 2 mA max (CMOS-level) - enables ultra-low-power retention during system sleep without external power gating |
| I/O Compatibility | TTL-input and TTL-output - eliminates level-shifter requirements when interfacing with 74LS/ALS or microcontroller GPIO |
| Operating Temperature | –45°C to +85°C - qualified for industrial automation, motor drives, and outdoor instrumentation |
| Package | 24-pin SOIC (SO24-2), 300-mil width - surface-mount compatible with standard reflow profiles and IPC-7351 footprints |

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, 45 ns access, 3.3 V core (with 5 V tolerant I/O), SOIC-28 package | Higher density and lower voltage, but requires level translation or redesign for pure 5 V systems | Select when upgrading capacity or migrating to 3.3 V infrastructure; not pin-compatible with IDT6116SA20SOI |
| AS6C1008-20TIN | 128K × 8, 20 ns access, 5 V operation, SOIC-28 package, higher ICC1 (120 mA vs. 80 mA) | Same speed grade and voltage, but larger memory map and incompatible pinout (28-pin vs. 24-pin) | Choose for increased buffer depth in new designs; requires PCB layout change and address decoding update |
Compared with CY62167EV30LL-45ZSXI and AS6C1008-20TIN, the IDT6116SA20SOI offers the only 24-pin SOIC 2K × 8 solution with guaranteed 20 ns industrial-temperature performance and native 5 V TTL compatibility - making it uniquely suitable for footprint-constrained legacy 5 V upgrades where density and voltage migration are secondary to timing predictability and drop-in replaceability.

FAQ
What is the maximum guaranteed access time for IDT6116SA20SOI across its rated temperature range?
IDT6116SA20SOI has a maximum guaranteed address access time (tAA) of 20 ns over its full industrial temperature range of –45°C to +85°C, measured at VCC = 4.5 V to 5.5 V. This specification is production-tested and applies to all units shipped under this part number, ensuring deterministic timing for real-time embedded applications without derating.
Does IDT6116SA20SOI support battery backup data retention like the LA variant?
No, IDT6116SA20SOI does not support battery backup data retention. That feature is exclusive to the LA suffix variants (e.g., IDT6116LA20SOI), which specify 2 V minimum retention voltage and sub-1 µA retention current. The SA version prioritizes speed and TTL drive strength over ultra-low-power retention capability.
Is IDT6116SA20SOI pin-compatible with other 24-pin 2K × 8 SRAMs such as the HM6116 or IS61C256?
IDT6116SA20SOI shares the industry-standard 24-pin SOIC pinout for 2K × 8 SRAMs (A0–A10, I/O0–I/O7, CS, WE, OE, VCC, GND), matching HM6116 and compatible with IS61C256's 28-pin variant only in functional signal mapping - not physical pinout. No PCB changes are needed when replacing HM6116LP-20 or equivalent 24-pin 2K × 8 SRAMs.
What are the two standby current specifications for IDT6116SA20SOI and how are they triggered?
IDT6116SA20SOI specifies two standby currents: ISB = 40 mA max (TTL-level standby) when CS > VIH, and ISB1 = 2 mA max (CMOS-level standby) when CS > VHC and all inputs are held at valid logic levels (VIL or VIH). The latter requires stricter input biasing but delivers 20× lower quiescent power for deep-sleep system states.
Can IDT6116SA20SOI operate reliably with a 5.5 V supply voltage?
Yes, IDT6116SA20SOI is fully specified for VCC = 5.0 V ±10%, meaning it operates reliably from 4.5 V to 5.5 V. All AC and DC parameters - including 20 ns access time, TTL compatibility, and standby currents - are guaranteed across this full voltage range at industrial temperatures, supporting designs with unregulated 5 V rails.
