Product details
Overview
IDT6116LA35SOG from Integrated Device Technology is a 16K-bit (2K × 8) low-power CMOS static RAM with 35 ns access time, TTL-compatible I/O, and battery-backed data retention at 2 V. It operates across industrial temperature range (–45°C to +85°C), supports asynchronous read/write cycles without clocks or refresh, and is packaged in 24-pin SOIC for high-density board layouts in embedded controllers and legacy instrumentation.
For engineers reviewing the IDT6116LA35SOG datasheet, IDT6116LA35SOG pinout, IDT6116LA35SOG application, or IDT6116LA35SOG equivalent, key selection criteria include standby current (≤25 µA in full CMOS standby), data retention capability (2 V min.), 24-pin SOIC footprint compatibility, and guaranteed 35 ns read cycle timing under industrial conditions.
Technical Context
This device implements a fully static, asynchronous memory architecture with dual power modes: active operation (CS < VIH) and two standby states-TTL-level (ISB ≤ 25 mA) and full CMOS-level (ISB1 ≤ 0.9 µA). Chip select (CS) directly controls power state transitions, enabling system-level power savings without external control logic.
The memory array uses a 128 × 128 configuration with address decoding for A0–A10 and bidirectional I/O0–I/O7 lines. All inputs meet TTL voltage thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V), and outputs drive ±4 mA/±8 mA loads while maintaining VOL ≤ 0.4 V and VOH ≥ 2.4 V at VCC = 4.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16,384 bits (2,048 × 8), enabling byte-wide data storage without external multiplexing |
| Access Time (tAA) | 35 ns max - guarantees deterministic read latency for real-time microcontroller interfaces |
| Supply Voltage | 5.0 V ±10% - compatible with standard TTL/CMOS logic rails and legacy 5 V systems |
| Data Retention Voltage | 2.0 V min - enables long-term data hold using coin-cell batteries during main power loss |
| Full Standby Current | 0.9 µA max at VCC = 5.5 V - reduces system quiescent power in sleep modes |
| Operating Temperature | –45°C to +85°C - qualified for industrial environments including factory automation and telecom infrastructure |
| Input/Output Compatibility | TTL-compatible - eliminates level-shifting requirements when interfacing with 74LS/74HC families |
Pinout & Package
Package: 24-pin Small Outline Integrated Circuit (SOIC), gull-wing lead form, 300 mil body width (SO24-2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit address bus supporting 2K-word addressing; no internal latching required |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface with high-impedance tri-state control via OE and CS |
| CS | Chip Select | Active-low enable controlling both memory access and automatic power-down entry |
| WE | Write Enable | Active-low signal qualifying write cycles; concurrent with CS LOW for valid write |
| OE | Output Enable | Active-low control for output drivers; allows read data gating independent of CS |
| VCC | Power Supply | +5 V supply pin; decoupling required within 1 cm for stable 35 ns timing |
| GND | Ground Reference | Signal and power return path; must be low-inductance connection for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Low-power standby mode | 0.9 µA full standby current enables >10-year battery backup life in maintenance-free systems |
| 2 V data retention | Operates down to 2.0 V VCC for nonvolatile data hold-no external backup controller needed |
| No clock or refresh required | Fully static design eliminates timing-critical refresh cycles and simplifies FPGA/microcontroller integration |
| TTL-compatible I/O | Direct interface with legacy 5 V logic families avoids level translators and reduces BOM count |
| MIL-STD-883 Class B compliance option | Available in military-grade variants (not this part), but industrial version shares same robust CMOS process |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-45ZSXIT | 512K × 16-bit, 45 ns access, 3.3 V only, no 2 V retention | Higher density but incompatible voltage and retention capability | Select only if migrating to 3.3 V systems and requiring larger memory space |
| AS6C1008-35PCN | 128K × 8-bit, 35 ns, 5 V, 2 V retention, 28-pin SOJ | Same retention and speed, but different pinout and package | Requires PCB redesign due to 28-pin SOJ vs. 24-pin SOIC; verify layout compatibility |
Compared with IDT6116LA35SOG, CY62167EV30LL-45ZSXIT offers higher density but lacks 2 V battery retention and requires 3.3 V operation, while AS6C1008-35PCN matches speed and retention but demands mechanical redesign for its 28-pin SOJ footprint.

FAQ
What is the maximum guaranteed access time for IDT6116LA35SOG?
IDT6116LA35SOG has a maximum guaranteed address access time (tAA) of 35 ns across the industrial temperature range (–45°C to +85°C) at VCC = 4.5 V to 5.5 V. This value is production-tested and specified in the AC Electrical Characteristics table under the "6116LA35" speed grade column.
Does IDT6116LA35SOG support true battery backup operation?
Yes, IDT6116LA35SOG supports true battery backup: it retains stored data at VCC as low as 2.0 V with typical current draw of 0.5–1.5 µA over temperature. This capability is exclusive to the LA (low-power) variant and is documented in the Data Retention Characteristics table (Table 10).
What package type is used for IDT6116LA35SOG?
IDT6116LA35SOG uses a 24-pin Small Outline Integrated Circuit (SOIC) package with gull-wing leads and a 300 mil body width (designated SO24-2 in IDT's ordering guide). Pin pitch is 1.27 mm, and the package complies with JEDEC MS-012 standards.
Can IDT6116LA35SOG operate without a clock or refresh signal?
Yes, IDT6116LA35SOG is a fully static RAM: it requires no clocks, timers, or periodic refresh cycles. Its CMOS latch-based memory cells retain data indefinitely as long as VCC remains within specification and CS is held HIGH during standby.
Is IDT6116LA35SOG pin-compatible with other 2K × 8 SRAMs like the HM6116?
IDT6116LA35SOG shares the industry-standard 24-pin DIP/SOIC pinout for 2K × 8 SRAMs (A0–A10, I/O0–I/O7, CS, WE, OE, VCC, GND), making it functionally and physically compatible with HM6116, 6116LP, and other JEDEC-compliant variants-though timing and power specs differ.
