Product details
Overview
IDT6116SA15SO8 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 dual standby modes (TTL- and CMOS-level), operates at 5.0 V ±10%, and is packaged in 24-pin SOIC for industrial temperature range (–45°C to +85°C) applications including embedded controllers and real-time data buffering.
For engineers reviewing the IDT6116SA15SO8 datasheet, IDT6116SA15SO8 pinout, IDT6116SA15SO8 application, or IDT6116SA15SO8 equivalent, key selection criteria include guaranteed 15 ns read cycle time, 2.2 V VIH compatibility with legacy TTL systems, low 40 mA ICC2 dynamic current, and SOIC-24 package suitability for high-density PCB layouts in avionics and test instrumentation.
Technical Context
The IDT6116SA15SO8 implements fully asynchronous static memory architecture with independent chip select (CS), output enable (OE), and write enable (WE) controls. Its address decoder drives a 128 × 128 memory array, supporting read cycles with tAA = 15 ns and tACS = 15 ns under commercial/industrial conditions.
It supports two distinct standby power states: ISB = 40 mA at TTL-level CS deassertion and ISB1 = 2 mA at CMOS-level CS deassertion, enabling system-level power optimization. All inputs meet VIH ≥ 2.2 V and VIL ≤ 0.8 V thresholds, ensuring interoperability with 5 V TTL logic families without level-shifting.

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 | 16 Mbit (2M × 8), 45 ns access, 3.3 V core, SOIC-32 package | Higher density but slower speed and incompatible voltage/logic family | Select only if migrating to 3.3 V systems and requiring >16 Kbyte capacity |
| AS6C1008-55PCN | 1 Mbit (128K × 8), 55 ns access, 5 V, SOIC-32 | Lower density, slower timing, larger package footprint | Use only for cost-sensitive replacements where 15 ns timing and 2K × 8 size are not required |
Compared with IDT6116SA15SO8, CY62167EV30LL-45ZSXI offers higher density but requires voltage translation and sacrifices 3× speed; AS6C1008-55PCN provides pin-compatible 5 V operation but doubles access time and increases board area-neither matches the 15 ns / SOIC-24 / industrial temp combination of IDT6116SA15SO8.

FAQ
What is the maximum guaranteed access time for IDT6116SA15SO8?
IDT6116SA15SO8 has a maximum guaranteed address access time (tAA) of 15 ns and read cycle time (tRC) of 15 ns across its specified industrial temperature range (–45°C to +85°C), as verified in the official IDT datasheet DSC-3089/03. This timing applies under VCC = 5.0 V ±10% and load conditions matching Figure 2 AC test setup. The "15" in the part number explicitly denotes this speed grade.
Does IDT6116SA15SO8 require a refresh clock or external timing signals?
No, IDT6116SA15SO8 is a fully static RAM and requires no refresh clock, timer, or external synchronization signals. Its internal circuitry maintains data indefinitely as long as VCC and GND are applied and CS remains asserted (LOW). This eliminates refresh controller logic and associated PCB routing complexity in microcontroller-based designs.
What are the valid logic voltage thresholds for IDT6116SA15SO8 inputs?
IDT6116SA15SO8 inputs accept VIH ≥ 2.2 V (minimum) and VIL ≤ 0.8 V (maximum) under VCC = 5.0 V ±10%, making them directly compatible with standard TTL logic families. These thresholds are guaranteed across the full industrial temperature range and do not require external biasing or pull-up resistors for reliable operation.
Can IDT6116SA15SO8 operate in battery backup mode?
No-battery backup data retention is exclusive to the LA variant (e.g., IDT6116LA20SO8). The IDT6116SA15SO8 is the standard-power version and does not support 2 V data retention. Its minimum operating VCC is 4.5 V, and it enters low-power standby (ISB = 40 mA) only when CS is deasserted-not a true battery-retention state.
Is IDT6116SA15SO8 pin-compatible with other 2K × 8 SRAMs in SOIC-24 packages?
IDT6116SA15SO8 follows the industry-standard 24-pin SOIC pinout for 2K × 8 SRAMs (A0–A10, I/O0–I/O7, CS, WE, OE, VCC, GND), matching JEDEC MS-012. However, timing parameters, drive strength, and standby behavior differ across vendors; direct substitution requires validation of tAA, ISB, and VIH/VIL margins in the target system.
