Product details
Overview
IDT6116SA35TP from Integrated Device Technology is a 16K-bit (2K × 8) high-speed CMOS static RAM with 35 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 asynchronous read/write cycles without clocks or refresh, and features dual standby modes - TTL-level (25 mA) and CMOS-level (2 mA) - for system power optimization in embedded controllers and data acquisition systems.
For engineers reviewing the IDT6116SA35TP datasheet, IDT6116SA35TP pinout, IDT6116SA35TP application, or IDT6116SA35TP equivalent, key selection considerations include its 24-pin plastic DIP (P24-1) package, 2K × 8 organization, guaranteed tAA ≤ 35 ns and tRC = 35 ns, low-power standby capability, and compatibility with legacy 6116-family designs requiring industrial-grade reliability.
Technical Context
The IDT6116SA35TP implements fully static asynchronous logic with no internal clocks or refresh circuitry. Its address decoder drives a 128 × 128 memory array, and control logic manages three-state I/O via independent CS, OE, and WE inputs. Read and write operations are decoupled: OE enables output drivers during reads, while WE gates write data latching - both active-low and TTL-compatible.
Two distinct standby modes are supported: TTL-level standby (ISB = 25 mA max) activates when CS > VIH, and full CMOS-level standby (ISB1 = 2 mA max) engages when CS > VHC and input levels are valid, enabling deep power savings in battery-backed or intermittently active systems. Data retention is not supported - that function is exclusive to the LA variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16,384 bits (2,048 words × 8 bits) - fits compact firmware buffers or real-time data logging in space-constrained 8-bit systems. |
| Access Time (tAA) | ≤35 ns max - enables direct interface with 20 MHz Z80, 8085, or 68000-based bus systems without wait states. |
| Supply Voltage | 5.0 V ±10% - compatible with standard TTL/CMOS logic rails; no external regulation required. |
| Operating Temperature | –45°C to +85°C - qualified for industrial environments including factory automation and telecom line cards. |
| Standby Current (ISB1) | 2 mA max (CMOS-level) - reduces idle power by >95% vs. active mode (ICC1 = 80 mA), critical for energy-sensitive applications. |
| 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) - ensures plug-and-play integration with legacy microprocessor buses. |
| Package | 24-pin 300-mil plastic DIP (P24-1) - supports through-hole prototyping and high-reliability industrial PCB assembly. |
Pinout & Package
Package: 24-pin 300-mil plastic DIP (P24-1), through-hole mounting, JEDEC MS-001 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A10 | Address Inputs | 11-bit binary address bus; selects one of 2,048 memory locations; TTL-compatible, no pull-ups required. |
| I/O0–I/O7 | Bi-directional Data Bus | 8-bit parallel data path; high-impedance when CS or OE inactive; drives/receives TTL levels directly. |
| CS | Chip Select | Active-low enable; asserts memory access; controls TTL- and CMOS-level standby entry/exit based on voltage threshold. |
| WE | Write Enable | Active-low write strobe; latches data on falling edge; must be coordinated with CS for valid write cycles. |
| OE | Output Enable | Active-low output control; enables I/O drivers during reads; independent of WE, allowing read-modify-write sequences. |
| VCC | Power Supply | +5 V supply pin; bypassing with 0.1 µF ceramic capacitor adjacent to pin is recommended for noise immunity. |
| GND | Ground Reference | Signal and power ground return; requires low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| No refresh required | Fully static architecture eliminates DRAM-style refresh overhead and timing constraints in microcontroller systems. |
| Dual standby modes | TTL-level (25 mA) and CMOS-level (2 mA) standby reduce system power across operational states without external logic. |
| TTL-compatible I/O | Direct interface with 8080, Z80, 6800, and 68000 families - no level-shifting or bus transceivers needed. |
| Industrial temperature grade | –45°C to +85°C operation validated per MIL-STD-883 Class B test methods - suitable for uncontrolled industrial enclosures. |
| Low alpha-particle sensitivity | CMOS process minimizes soft-error rate - critical for long-term data integrity in non-volatile buffer applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY6116BV35LL-PLXC | 35 ns access, 5 V, 2K × 8, SOIC-28 package - larger footprint, different pinout, no DIP option. | Requires PCB layout change; better suited for new surface-mount designs than legacy through-hole upgrades. | Select if migrating to SMT and need Cypress's extended lifecycle support beyond IDT's discontinued status. |
| AS6C1008-35PCN | 35 ns access, 5 V, 2K × 8, 24-pin DIP - same package and pinout; lower ICC1 (65 mA vs. 80 mA) but no industrial temp rating (0°C to +70°C only). | Limited to commercial-temperature applications; unsuitable for factory-floor or outdoor telecom deployments. | Choose for cost-sensitive commercial systems where ambient stays below +70°C and board space allows same-footprint replacement. |
Compared with IDT6116SA35TP, CY6116BV35LL-PLXC demands PCB redesign due to SOIC-28 packaging, while AS6C1008-35PCN matches the DIP-24 footprint but sacrifices industrial temperature capability - making IDT6116SA35TP uniquely suited for drop-in upgrades in harsh-environment legacy systems.

FAQ
What is the maximum guaranteed access time for IDT6116SA35TP?
The IDT6116SA35TP has a maximum guaranteed address access time (tAA) of 35 ns and a read cycle time (tRC) of 35 ns, both specified across the full industrial temperature range (–45°C to +85°C) at VCC = 5.0 V ±10%. These values are production-tested and apply to the SA (standard power) variant in the P24-1 package.
Does IDT6116SA35TP support battery backup or data retention?
No, IDT6116SA35TP does not support battery backup or low-voltage data retention. That capability is exclusive to the LA (low-power) variants such as IDT6116LA35TP, which specify 2 V data retention voltage and sub-µA retention current. The SA suffix denotes standard power operation only.
What package type is used for IDT6116SA35TP?
IDT6116SA35TP uses a 24-pin 300-mil plastic DIP package, designated P24-1 in IDT's ordering nomenclature. This through-hole package is compatible with standard DIP-24 sockets and supports manual or wave-solder assembly in industrial PCBs.
Can IDT6116SA35TP be used as a direct replacement for older 6116-series SRAMs?
Yes, IDT6116SA35TP is pin-compatible and functionally equivalent to other 2K × 8 6116-family SRAMs with 24-pin DIP packaging, including the original Mostek MK6116 and early IDT IDT6116SA variants. Its TTL-compatible I/O, identical pinout, and 35 ns timing make it a verified drop-in upgrade for legacy systems.
What are the standby current specifications for IDT6116SA35TP?
IDT6116SA35TP specifies two standby current modes: ISB = 25 mA maximum under TTL-level standby (CS > VIH), and ISB1 = 2 mA maximum under full CMOS-level standby (CS > VHC with valid input levels). Both are measured at VCC = 5.5 V and f = 0, enabling significant system-level power savings during idle periods.
