Product details
Overview
6116LA150TDB from Renesas Electronics is a 16K-bit (2K × 8) low-power CMOS static RAM with 150ns maximum access time, TTL-compatible I/O, and battery backup data retention at 2V. It operates across military temperature range (–55°C to +125°C), features automatic standby mode on chip select high, and is housed in a 24-pin ceramic DIP (SD24) package for high-reliability embedded systems.
For engineers reviewing the 6116LA150TDB datasheet, 6116LA150TDB pinout, 6116LA150TDB application, or 6116LA150TDB equivalent, this page delivers verified timing specs, military-grade reliability data, standby current values (0.1mA typical), pin-level functional roles, and direct alternatives for legacy SRAM replacement in avionics, defense computing, and ruggedized industrial controllers.
Technical Context
The 6116LA150TDB implements fully static asynchronous operation-no clocks or refresh required-and uses advanced CMOS process to eliminate alpha-particle soft errors. Its control logic supports three distinct operational modes: standby (CS = HIGH), read (CS = LOW, OE = LOW, WE = HIGH), and write (CS = LOW, WE = LOW), with all inputs/outputs meeting TTL voltage thresholds.
It integrates a 128 × 128 memory array with address decoder, I/O control, and input data circuitry. Standby power reduction is achieved via dual-level chip select detection: TTL-level standby (ISB = 40µA max) and full CMOS-level standby (ISB1 = 0.9µA max), enabling ultra-low-power data retention during system sleep states.
Key Specifications

|---|---|
| Memory Organization | 2K × 8-bit (16,384 bits), byte-wide parallel interface |
| Access Time (tAA) | 150ns max at VCC = 5.0V ±10%, TA = –55°C to +125°C - defines minimum time between address valid and valid data output |
| Standby Current (ISB1) | 0.9µA max at VCC = 5.5V, CS > VHC - enables multi-year battery-backed data retention |
| Data Retention Voltage | 2.0V min - allows operation from single-cell lithium or backup coin cell without regulator |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV25616AL-15TQLI | 3.3V-only supply, 15ns access, 256K × 16 organization - higher density but incompatible voltage and bus width | Requires level translation and PCB redesign; suited for modern low-voltage embedded systems, not drop-in 5V replacement | Select only if migrating to 3.3V architecture and increasing memory depth; not suitable for pin-for-pin or functional substitution. |
| AS6C4008-15PCN | 5V supply, 15ns access, same 2K × 8 organization and 24-pin PDIP package - but commercial temp range (0°C to +70°C) only | Lacks military qualification, no 2V data retention, higher ISB (2µA vs. 0.9µA max) | Valid for cost-sensitive commercial designs where extended temperature and battery backup are not required. |
Compared with IS61LV25616AL-15TQLI and AS6C4008-15PCN, the 6116LA150TDB uniquely combines military temperature rating, 2V data retention, and proven 5V TTL compatibility - making it irreplaceable in legacy avionics, defense electronics, and industrial systems where qualification continuity and power-fail resilience are mandatory.

FAQ
What is the maximum operating temperature range supported by the 6116LA150TDB?
The 6116LA150TDB is rated for operation from –55°C to +125°C and is manufactured in compliance with MIL-STD-883, Class B. This military-grade temperature range ensures reliable functionality in extreme environments such as aircraft bays, missile guidance sections, and desert-deployed communications gear - confirmed by Renesas' datasheet revision 07/17/20.
Does the 6116LA150TDB require a refresh clock or external timing circuitry?
No, the 6116LA150TDB is a fully static RAM and requires no refresh clock or external timing signals. Its internal design uses static CMOS latches, allowing indefinite data retention as long as power is applied - a key feature confirmed in the Functional Block Diagram and DC Electrical Characteristics section of the Renesas datasheet for 6116LA150TDB.
What is the minimum supply voltage required to maintain data during battery backup mode for the 6116LA150TDB?
The 6116LA150TDB guarantees data retention down to 2.0V (VDR), as specified in the Data Retention Characteristics table. At this voltage, ICCDR remains ≤ 300µA across the full military temperature range - enabling use with common 2V lithium batteries or backup cells without regulation, per Renesas' 6116SA/LA datasheet Section 4.
Is the 6116LA150TDB pin-compatible with other members of the IDT6116SA/LA family?
Yes, the 6116LA150TDB shares identical pinout, signal definitions, and package (SD24 ceramic DIP) with all IDT6116SA/LA variants including 6116SA20TDB and 6116LA25TDB. This uniformity allows speed-grade interchangeability in existing designs - confirmed by Pin Configuration diagrams and Ordering Information tables in the Renesas 6116SA/LA datasheet.
What is the typical standby current consumption of the 6116LA150TDB in full CMOS-level standby mode?
In full CMOS-level standby mode (ISB1), the 6116LA150TDB draws 0.1µA typical and 0.9µA maximum at VCC = 5.5V and TA = +25°C, as documented in Table 8 of the Renesas datasheet. This ultra-low current enables multi-year data retention on small backup batteries - a defining characteristic of the LA (low-power) version of the 6116LA150TDB.
