Product details
Overview
IDT6116SA45SOI8 from Integrated Device Technology is a 16K-bit (2K × 8) high-speed CMOS static RAM with 45 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 full static asynchronous operation (no clock or refresh), and features dual standby modes-TTL-level (25 mA) and CMOS-level (0.1 mA)-for power-sensitive embedded control and data buffering applications.
For engineers reviewing the IDT6116SA45SOI8 datasheet, IDT6116SA45SOI8 pinout, IDT6116SA45SOI8 application, or IDT6116SA45SOI8 equivalent, key selection criteria include access time vs. power trade-offs, industrial-grade reliability, SOIC-24 package compatibility, and direct replacement feasibility in legacy SRAM-based memory subsystems.
Technical Context
The IDT6116SA45SOI8 implements a fully static 128 × 128 memory array with asynchronous address decoding and TTL-compatible input/output buffers. Its control logic supports three operational modes-standby (CS HIGH), read (CS & OE LOW, WE HIGH), and write (CS & WE LOW)-with guaranteed timing across industrial temperature.
It uses advanced CMOS process technology to eliminate alpha-particle soft errors and enables battery-backed data retention only in LA variants-not applicable to the SA version. The device requires no external clocks, refresh circuitry, or initialization sequences, simplifying integration into microcontroller-based systems and real-time controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16,384 bits (2K × 8), supporting byte-wide data bus interfacing without external multiplexing |
| Access Time (tAA) | 45 ns max - defines minimum address-to-valid-data delay in read cycles under industrial conditions |
| Supply Voltage | 5.0 V ±10% - compatible with standard TTL/CMOS logic rails; no separate VDD/VSS sequencing required |
| Operating Temperature | –45°C to +85°C - qualified for industrial environments including factory automation and transportation electronics |
| Standby Current (ISB) | 25 mA max (TTL-level), 0.1 mA max (CMOS-level) - enables low-power sleep states in battery-assisted systems |
| I/O Compatibility | TTL input thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V) and output drive (VOH ≥ 2.4 V @ –4 mA, VOL ≤ 0.4 V @ 8 mA) |
| Package | 24-pin SOIC (SO24-2), 300-mil width - surface-mount compatible with standard reflow profiles and IPC-7351 footprints |
Pinout & Package
Package: 24-pin Small Outline Integrated Circuit (SOIC), 300-mil body width, gull-wing lead form per JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit address bus accepting parallel addressing for full 2K-word selection; no latching or strobing required |
| I/O0–I/O7 | Bi-directional Data Bus | 8-bit TTL-compatible data path; high-impedance during CS HIGH or write cycles unless OE asserted |
| CS | Chip Select | Active-low enable controlling device activation and automatic entry into standby mode when deasserted |
| WE | Write Enable | Active-low signal enabling write operations; must be coordinated with CS and address stability per tAS/tWP specs |
| OE | Output Enable | Active-low control for output drivers; allows shared bus operation by disabling outputs independently of CS |
| VCC | Power Supply | +5 V supply pin; decoupling capacitor placement near this pin is critical for AC noise immunity |
| GND | Ground Reference | Signal and power ground return; requires low-inductance connection to minimize switching noise coupling |

FAQ
What is the maximum operating temperature range for IDT6116SA45SOI8?
IDT6116SA45SOI8 is rated for industrial temperature operation from –45°C to +85°C. This specification is guaranteed per the datasheet's Recommended Operating Conditions table and applies across all DC and AC parameters. The device does not support military-grade (–55°C to +125°C) or commercial-only (0°C to +70°C) ranges. Thermal derating is not required within this band.
Does IDT6116SA45SOI8 support battery backup data retention?
No, IDT6116SA45SOI8 does not support battery backup data retention. That feature is exclusive to the LA variant (e.g., IDT6116LA45SOI8), which specifies 2 V data retention voltage and sub-microwatt standby current. The "SA" suffix denotes standard power operation only, with minimum VCC = 4.5 V for functional operation.
Is IDT6116SA45SOI8 pin-compatible with other 2K×8 SRAMs in SOIC-24 packages?
IDT6116SA45SOI8 follows industry-standard 2K×8 SRAM pinouts (A0–A10, I/O0–I/O7, CS, WE, OE, VCC, GND) and is functionally pin-compatible with equivalents like HM6116LP-4, DS1225Y-45, and MB8116-45 in SOIC-24. However, timing margins and leakage behavior differ-system validation is required before substitution.
What is the standby current consumption of IDT6116SA45SOI8?
IDT6116SA45SOI8 has two standby modes: TTL-level standby draws up to 25 mA when CS > VIH, and CMOS-level standby draws up to 0.1 mA when CS > VHC and inputs are held at valid logic levels. The latter requires strict input biasing but enables ultra-low-power hold states in energy-constrained applications.
Can IDT6116SA45SOI8 operate at 3.3 V?
No, IDT6116SA45SOI8 is specified only for 5.0 V ±10% operation (4.5 V to 5.5 V). Its TTL-compatible inputs require VIH ≥ 2.2 V and VIL ≤ 0.8 V, and its internal logic thresholds are optimized for 5 V. Operation below 4.5 V violates datasheet limits and may result in undefined read/write behavior or increased bit error rates.
