Product details
Overview
IDT6116SA45TP from Integrated Device Technology is a 16K-bit (2K × 8) high-speed CMOS static RAM with 45ns maximum access time, TTL-compatible I/O, and 24-pin plastic DIP (300 mil) packaging. It operates at 5.0V ±10%, supports industrial temperature range (–45°C to +85°C), and features automatic standby mode when CS is HIGH - enabling low-power system design in embedded controllers and data acquisition modules.
For engineers reviewing the IDT6116SA45TP datasheet, IDT6116SA45TP pinout, IDT6116SA45TP application, or IDT6116SA45TP equivalent, key selection considerations include its 45ns read cycle time, 25mA TTL-level standby current, 2K × 8 asynchronous architecture, and compatibility with legacy 6116-family memory interfaces in industrial instrumentation and military-grade avionics subsystems.
Technical Context
The IDT6116SA45TP implements fully static asynchronous operation with no clocks or refresh required. Its address decoder drives a 128 × 128 memory array, and control logic enforces strict timing for CS-, OE-, and WE-controlled read/write cycles per JEDEC-standard 6116 timing diagrams.
It uses advanced CMOS process technology to eliminate alpha-particle soft errors and supports dual standby modes: TTL-level (ISB = 25mA max) and CMOS-level (ISB1 = 2mA max) power reduction, triggered by CS voltage thresholds (VIH/VHC) and input voltage levels (VLC/VHC).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16,384 bits (2K × 8), supporting byte-wide data bus interfacing without external demultiplexing |
| Access Time | 45ns max (tAA, tACS), defining minimum address-to-data-valid delay in high-speed microcontroller co-processor systems |
| Supply Voltage | 5.0V ±10%, compatible with standard TTL/CMOS logic rails and eliminating need for dedicated LDO regulation |
| Operating Temp | –45°C to +85°C (industrial grade), validated for use in motor drives and factory automation PLCs |
| Standby Current | 25mA max (TTL-level ISB), enabling rapid wake-up from low-power sleep states in battery-backed data loggers |
| I/O Compatibility | TTL-input and TTL-output levels (VIH = 2.2V min, VOL = 0.4V max), ensuring direct interface with 74LS/74F logic families |

Pinout & Package
24-pin plastic DIP (300 mil, P24-1) package with gull-wing lead form, 0.3-inch body width, and 0.1-inch lead pitch - suitable for wave soldering and manual prototyping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit address bus accepting 0–2047 row/column select signals for full 2K memory addressing |
| I/O0–I/O7 | Data Input/Output | Bidirectional 8-bit data bus with high-impedance tri-state control via OE and CS |
| CS | Chip Select | Active-LOW enable that gates all internal operations and triggers TTL-level standby mode when HIGH |
| WE | Write Enable | Active-LOW signal controlling write cycle initiation; must be synchronized with CS and address stability |
| OE | Output Enable | Active-LOW control for output drivers only; does not affect write functionality or standby entry |
| VCC | Power Supply | +5V supply pin requiring local 0.1µF ceramic decoupling adjacent to package |
| GND | Ground Reference | Signal and power ground return path shared across all inputs, outputs, and internal circuitry |
Key Features

|---|---|---|---|
| CY62167EV30LL-45ZSXIT | 3V core, 45ns access, 512K × 16 organization, SOIC-44 package | Requires voltage translation and bus-width adaptation; unsuitable for direct 8-bit 24-pin DIP replacement | Select only when migrating to 3.3V systems with wider data paths and surface-mount constraints |
| AS6C1008-45ZIN | 5V, 45ns, 128K × 8, 32-pin SOJ, higher density but different pinout and timing margins | Not pin-compatible; requires PCB layout change and timing validation for tOH/tCHZ compliance | Choose only for capacity upgrade paths where board revision and firmware revalidation are planned |
Compared with CY62167EV30LL-45ZSXIT and AS6C1008-45ZIN, the IDT6116SA45TP delivers verified 2K × 8 byte-wide operation in legacy 24-pin DIP packaging - preserving mechanical fit, signal routing, and timing margins in field-deployed industrial hardware without redesign.

FAQ
What is the maximum operating temperature range for the IDT6116SA45TP?
The IDT6116SA45TP is rated for industrial temperature operation from –45°C to +85°C, as confirmed in the "Recommended Operating Temperature and Supply Voltage" table (DSC-3089/03, p.3). This specification applies specifically to the SA variant in TP (plastic DIP) packaging and is distinct from the military-grade LA version's –55°C to +125°C rating.
Does the IDT6116SA45TP require a refresh clock or external timing signals?
No, the IDT6116SA45TP is a fully static RAM and requires no refresh clock or external timing signals. Its asynchronous architecture uses only CS, WE, OE, and address inputs to control read/write cycles - as stated in the "Description" section (p.1) and verified by the "Static operation: no clocks or refresh required" feature bullet.
Can the IDT6116SA45TP be used as a direct replacement for older 6116-series SRAMs in existing designs?
Yes, the IDT6116SA45TP maintains pin-for-pin compatibility and identical 24-pin DIP (P24-1) footprint with industry-standard 6116 SRAMs. Its TTL-compatible I/O levels, 5V supply, and 45ns timing align with JEDEC 6116 specifications - enabling drop-in replacement without layout or firmware changes in legacy systems.
What is the standby current consumption of the IDT6116SA45TP when CS is HIGH?
When CS is driven HIGH, the IDT6116SA45TP enters TTL-level standby mode with ISB ≤ 25mA (max) at VCC = 5.5V and f = fMAX, as specified in Table 8 (p.4) for the 6116SA45 industrial variant. This value is measured with outputs open and confirms low-power operation during system idle periods.
Is battery backup supported on the IDT6116SA45TP?
No, battery backup data retention is exclusive to the LA (low-power) variant, such as IDT6116LA45TP. The IDT6116SA45TP is the standard-power version and does not support 2V data retention - as explicitly noted in the "Features" section ("Battery backup operation – 2V data retention voltage (LA version only)")
