Product details
Overview
IDT6116LA45SOGI8 from Integrated Device Technology is a 16K-bit (2K × 8) low-power CMOS static RAM with 45 ns maximum 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 static operation without clocks or refresh, and is packaged in 24-pin SOIC (300 mil gull-wing). Used in legacy industrial controllers and embedded instrumentation requiring non-volatile SRAM holdover.
For engineers reviewing the IDT6116LA45SOGI8 datasheet, IDT6116LA45SOGI8 pinout, IDT6116LA45SOGI8 application, or IDT6116LA45SOGI8 equivalent, key selection criteria include its 45 ns read cycle time, 2V data retention capability, industrial-grade temperature rating, SOIC-24 package compatibility, and TTL-level interface compliance - all critical for maintaining legacy system reliability during power interruption or brownout conditions.
Technical Context
The IDT6116LA45SOGI8 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 random access with no internal timing constraints beyond tRC, tAA, and tACS.
It features dual standby modes: TTL-level standby (ISB = 20 mA max at VCC = 5.5 V) and full CMOS-level standby (ISB1 = 0.1 µA typical at VCC = 5.5 V), plus guaranteed 2 V data retention (ICCDR ≤ 30 µA) across –45°C to +85°C. Input/output capacitance is specified at 8 pF each.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16,384 bits (2K × 8), enabling byte-wide data storage without external multiplexing |
| Access Time (tAA) | 45 ns max - defines minimum address-to-valid-data delay in read cycles |
| Data Retention Voltage | 2.0 V min - allows backup from coin-cell or low-voltage auxiliary supply during main power loss |
| Standby Current (ISB1) | 0.1 µA typical at CMOS-level CS deassertion - enables ultra-low-power hold mode in battery-critical systems |
| Operating Temperature | –45°C to +85°C - qualified for industrial environments including factory automation and telecom infrastructure |
| I/O Interface | TTL-compatible inputs/outputs - eliminates level-shifting requirements when interfacing with legacy 5 V microcontrollers |

| I/O0–I/O7 | Bi-directional Data Bus | 8-bit parallel interface supporting simultaneous read/write with high-impedance tri-state control |
| CS | Chip Select | Active-low enable controlling device activation and automatic entry into standby mode when HIGH |
| WE | Write Enable | Active-low signal qualifying write operations; must be LOW concurrent with CS LOW and stable address |
| OE | Output Enable | Active-low control for output drivers; allows read data to appear on I/O lines only when asserted |
| VCC | Power Supply | +5.0 V ±10% supply rail; powers core logic and I/O buffers |

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, 3.3 V core, 45 ns access, TSOP-44 package | Higher density and lower voltage, but incompatible pinout and wider package | Select only if redesigning PCB for higher capacity and modern 3.3 V systems; not drop-in |
| AS6C1008-45ZIN | 128K × 8-bit, 5 V, 45 ns, SOIC-28 package, no 2 V retention | Larger capacity and same speed, but lacks battery backup and uses 28-pin SOIC | Use when extended memory depth is required and 2 V retention is unnecessary; board layout change needed |
Compared with IDT6116LA45SOGI8, CY62167EV30LL-45ZSXIT offers greater density and lower voltage operation but requires full system voltage and layout revision, while AS6C1008-45ZIN provides more storage in a larger SOIC package but omits the critical 2 V data retention feature essential for legacy holdover designs.

FAQ
What is the guaranteed data retention voltage for IDT6116LA45SOGI8?
IDT6116LA45SOGI8 guarantees data retention down to 2.0 V across its rated industrial temperature range (–45°C to +85°C), with typical retention current of 0.5–30 µA depending on temperature and VCC. This enables reliable operation from lithium coin cells or low-voltage auxiliary supplies during main power failure.
Does IDT6116LA45SOGI8 require a clock or refresh signal?
No, IDT6116LA45SOGI8 is a fully static RAM and requires no clock, refresh cycles, or wait states. Its asynchronous design relies solely on address, CS, OE, and WE timing - simplifying integration with microcontrollers, FPGAs, and legacy bus architectures that lack dedicated memory controllers.
What package type is used for IDT6116LA45SOGI8?
IDT6116LA45SOGI8 is supplied in a 24-pin Small Outline Integrated Circuit (SOIC) package with 300 mil body width and gull-wing leads (JEDEC MO-012AC, IDT designation SO24-2). It is RoHS-compliant and compatible with standard surface-mount reflow processes.
How does the standby power consumption differ between TTL and CMOS-level chip select for IDT6116LA45SOGI8?
When CS is driven to TTL HIGH (>2.2 V), IDT6116LA45SOGI8 draws up to 20 mA (ISB). When CS is pulled to CMOS HIGH (>VCC – 0.2 V), it enters full standby mode drawing only 0.1 µA (ISB1). This two-tier behavior allows flexible power management based on system-level voltage rail capabilities.
Is IDT6116LA45SOGI8 pin-compatible with other IDT6116 variants?
Yes, IDT6116LA45SOGI8 shares identical pinout and function mapping with all IDT6116SA/LA family members in the same package (e.g., IDT6116LA25SOGI8, IDT6116SA45SOGI8), differing only in access speed, power profile, and temperature grade - enabling speed-bin upgrades without PCB changes.
