Product details
Overview
IDT6116SA35SOI from Integrated Device Technology is a 16K-bit (2K × 8) high-speed CMOS static RAM with 35 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 asynchronous static operation without clocks or refresh, and is packaged in 24-pin SOIC for board-level density in embedded control and data buffering applications.
For engineers reviewing the IDT6116SA35SOI datasheet, IDT6116SA35SOI pinout, IDT6116SA35SOI application, or IDT6116SA35SOI equivalent, key selection criteria include guaranteed 35 ns read cycle time (tRC), standby current of 25 mA (TTL-level) and 2 mA (CMOS-level), 24-pin SOIC package compatibility, and industrial-grade reliability per MIL-STD-883 Class B test methodology.
Technical Context
The IDT6116SA35SOI implements fully static asynchronous 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 three distinct operational modes: read (CS=L, OE=L, WE=H), write (CS=L, WE=L), and standby (CS=H).
It features dual standby power modes: TTL-level standby (ISB = 25 mA max at fMAX) and CMOS-level full standby (ISB1 = 2 mA max), activated by CS voltage thresholds (VIH/VHC). Input and output circuits are designed for direct TTL interfacing, with VIH = 2.2 V min and VOL = 0.4 V max at IOL = 8 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2K × 8-bit (16,384 bits), byte-wide parallel interface |
| Access Time (tAA) | 35 ns max - defines minimum address-to-data valid delay in read cycles |
| Read Cycle Time (tRC) | 35 ns max - sets shortest interval between successive read operations |
| Supply Voltage | 5.0 V ±10% - compatible with standard TTL logic rails and legacy 5 V systems |
| Operating Temperature | –45°C to +85°C - qualified for industrial environments including factory automation and telecom infrastructure |
| Standby Current (ISB1) | 2 mA max at CMOS-level CS - enables ultra-low-power hold mode when CS > VHC |
| I/O Compatibility | TTL-input and TTL-output - eliminates level-shifting requirements in mixed-logic designs |
Pinout & Package
Package: 24-pin Small Outline Integrated Circuit (SOIC), gull-wing lead form, 300 mil body width (SO24-2), RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit binary address bus selecting one of 2K memory locations |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel data path for read/write transfers; high-impedance when CS or OE inactive |
| CS | Chip Select | Active-low enable controlling device activation and standby entry (ISB/ISB1 transition) |
| WE | Write Enable | Active-low signal qualifying write cycles; latches data on falling edge when CS active |
| OE | Output Enable | Active-low control for output drivers; allows shared bus operation with tristate isolation |
| VCC | Power Supply | +5 V supply pin; decoupling required within 1 cm for stable 35 ns timing |
| GND | Ground Reference | Signal and power return; must be low-inductance connection to minimize noise coupling |
Key Features

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 | 512K × 16-bit, 45 ns access, 3.3 V supply, 44-pin TSOP | Higher density and lower voltage but incompatible pinout and voltage domain | Select only if migrating to 3.3 V systems and redesigning PCB layout and power delivery |
| AS6C1008-35PCN | 128K × 8-bit, 35 ns access, 5 V supply, 28-pin SOIC | Same speed and voltage, but larger package and higher capacity increases cost and footprint | Choose when future memory expansion is required and 28-pin routing is acceptable |
Compared with IDT6116SA35SOI, CY62167EV30LL-45ZSXI requires full voltage and interface redesign, while AS6C1008-35PCN retains 5 V and 35 ns performance but demands PCB rework for 28-pin SOIC - neither offers drop-in replacement capability.

FAQ
What is the maximum operating temperature range for IDT6116SA35SOI?
IDT6116SA35SOI is rated for industrial temperature operation from –45°C to +85°C. This range is validated per manufacturer specifications and supported by MIL-STD-883 Class B screening, making it suitable for factory automation, outdoor telecom equipment, and transportation control systems where ambient temperatures exceed commercial limits.
Does IDT6116SA35SOI require a clock or refresh signal?
No, IDT6116SA35SOI is a fully static RAM and requires no clock or periodic refresh. Its CMOS latch-based memory cells retain data indefinitely as long as VCC is applied and CS remains active or in standby mode - eliminating timing-critical refresh controllers and simplifying system design.
What is the meaning of "SOI" in the part number IDT6116SA35SOI?
In IDT6116SA35SOI, "SOI" denotes the package variant: 24-pin Small Outline IC (SOIC) with gull-wing leads and 300 mil body width (designated SO24-2 in IDT documentation). It is not a process technology identifier - the device uses standard high-performance CMOS fabrication.
Can IDT6116SA35SOI operate with a 3.3 V supply?
No, IDT6116SA35SOI is specified only for 5.0 V ±10% operation (4.5 V to 5.5 V). Its input thresholds (VIH = 2.2 V min), output drive strength (VOL = 0.4 V at 8 mA), and internal logic levels are designed exclusively for 5 V TTL compatibility - using 3.3 V will result in undefined behavior and failure to meet timing specs.
How does the standby power mode function in IDT6116SA35SOI?
IDT6116SA35SOI enters standby when CS is driven HIGH. At TTL-level CS (VIH), ISB = 25 mA max; at CMOS-level CS (VHC), ISB1 = 2 mA max. The latter requires strict input voltage control but achieves >90% power reduction - critical for battery-backed or thermally constrained systems using IDT6116SA35SOI.
