Product details
Overview
IDT6116LA45SOGI 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 down to 2V. 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 for high-density PCB layouts - used in legacy industrial controllers and embedded instrumentation requiring nonvolatile SRAM backup.
For engineers reviewing the IDT6116LA45SOGI datasheet, IDT6116LA45SOGI pinout, IDT6116LA45SOGI application, or IDT6116LA45SOGI equivalent, key selection criteria include standby current (≤20 µA at CMOS-level chip deselect), data retention capability at 2V, 24-pin SOIC footprint compatibility, and industrial-grade reliability per MIL-STD-883 Class B test methods.
Technical Context
The IDT6116LA45SOGI implements fully static asynchronous memory architecture with no internal clocks or refresh circuitry. Its control logic uses independent Chip Select (CS), Output Enable (OE), and Write Enable (WE) inputs to manage read/write cycles and high-impedance I/O states.
It features dual standby modes: TTL-level standby (ISB ≤ 20 mA) when CS > VIH, and ultra-low-power full standby (ISB1 ≤ 0.9 µA) when CS > VHC and all inputs held at valid logic levels - enabling system-level power savings during idle periods while preserving data integrity.

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 | 32K × 8 organization, 3.3 V core, 45 ns access, SOIC-28 package | Requires level translation for 5 V systems; larger capacity but incompatible pinout | Select only if migrating to 3.3 V architecture and needing higher density |
| AS6C1008-45ZIN | 128K × 8, 5 V, 45 ns, SOIC-28, no battery retention | Lacks 2 V data retention; higher capacity but not drop-in replacement | Use when extended memory depth is prioritized over battery backup capability |
Compared with IDT6116LA45SOGI, CY62167EV30LL-45ZSXIT offers double density but requires voltage translation and board redesign, while AS6C1008-45ZIN provides greater capacity without data retention - making IDT6116LA45SOGI uniquely suited for industrial systems needing compact, battery-backed 2K × 8 SRAM in 24-pin SOIC.

FAQ
What is the guaranteed data retention voltage for IDT6116LA45SOGI?
IDT6116LA45SOGI guarantees data retention down to 2.0 V (VDR), as specified in Table 10 of the datasheet. This allows direct connection to a 2 V lithium battery or coin cell without regulation, sustaining memory contents during main power loss. The device draws ≤1.5 µA in this mode at +25°C, enabling multi-year backup operation in industrial settings.
Does IDT6116LA45SOGI require external refresh circuitry or clocks?
No, IDT6116LA45SOGI is a fully static RAM and requires no clocks, timers, or refresh signals. Its CMOS latch-based memory cells retain data indefinitely as long as VCC remains within specification and CS is asserted appropriately. This eliminates timing-critical refresh overhead in microcontroller-based designs and reduces system complexity.
What is the maximum operating temperature range supported by IDT6116LA45SOGI?
IDT6116LA45SOGI is rated for industrial temperature operation from –45°C to +85°C, as confirmed in the "Recommended Operating Temperature and Supply Voltage" table (Table 5). This range exceeds commercial-grade SRAMs and supports deployment in factory-floor controllers, outdoor telemetry units, and transportation electronics exposed to wide thermal swings.
Can IDT6116LA45SOGI be used as a direct replacement for IDT6116SA45SOGI?
IDT6116LA45SOGI is pin-compatible with IDT6116SA45SOGI but differs in power behavior: LA version adds 2 V data retention and lower standby current (0.9 µA vs. 2 mA), while SA version has higher active current. Substitution is electrically safe but requires verifying that the host system's power management accommodates LA's deeper standby state and battery interface.
What package type does IDT6116LA45SOGI use, and is it RoHS-compliant?
IDT6116LA45SOGI uses a 24-pin SOIC (SO24-2) package with gull-wing leads and 300-mil body width. Per IDT's 2001 datasheet and historical compliance records, this variant predates RoHS enforcement and contains leaded solder terminations; however, Aetrix Electronics supplies only RoHS-compliant reflows and traceable lot-controlled material per customer request.
