Product details
Overview
5962-8874001LA from Renesas Electronics is a military-grade 16K-bit (2K × 8) CMOS static RAM with 20ns access time, 2V data retention capability, TTL-compatible I/O, and full static operation requiring no clocks or refresh. It operates across –55°C to +125°C and is packaged in 24-pin ceramic DIP (SD24), designed for high-reliability avionics and defense computing systems.
For engineers reviewing the 5962-8874001LA datasheet, 5962-8874001LA pinout, 5962-8874001LA application, or 5962-8874001LA equivalent, this page delivers verified timing specs, military-grade DC/AC characteristics, battery-backed retention behavior, MIL-STD-883 Class B compliance, and precise package-to-pin mapping - all confirmed against Renesas' official 2020 rebranded datasheet.
Technical Context
The 5962-8874001LA implements fully static asynchronous architecture with three-state bidirectional I/Os controlled by CS, OE, and WE. Its dual-mode power management includes TTL-level standby (ISB ≤ 45mA) and CMOS-level full standby (ISB1 ≤ 0.9mA), enabling system-level power savings without external control logic.
It features deterministic read/write timing governed by tRC (read cycle time), tWC (write cycle time), and tCDR (chip deselect to data retention time), all guaranteed over the full military temperature range. Data retention at 2V is validated per MIL-STD-883, Method 1017, with ICCDR ≤ 300µA at 125°C.
Key Specifications

| WE | Write Enable | Active-low control for write cycles; overlaps with CS LOW to initiate write; determines tWP timing |
| OE | Output Enable | Active-low control for read output drivers; independent of WE, allowing read-modify-write sequences |
| VCC | Power Supply | +5V supply pin; decoupling required within 0.5 inch per MIL-STD-275 for EMI suppression |
| GND | Ground Reference | Signal and power return; must be connected to low-inductance ground plane per MIL-HDBK-454 |
Key Features
| Feature | Design Value |
|---|---|
| Battery-backed data retention | Operates down to 2.0V with ICCDR ≤ 300µA at 125°C - sustains memory state during brownout or battery-switchover |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8763301XA | Same 2K×8 organization, 25ns access, but no 2V data retention; rated –55°C to +125°C, SD24 package | Lacks battery backup capability - unsuitable for brownout-resilient designs | Select only if system has continuous 5V supply and retention is handled externally |
| 5962-9213901MXA | 2K×8, 20ns, 2V retention, but plastic DIP (PTG24); MIL-STD-883 Class B screened, not hermetic | Lower moisture resistance and thermal cycling endurance than ceramic SD24 | Acceptable for ground vehicle non-hermetic enclosures where cost outweighs long-term hermeticity |
Compared with 5962-8874001LA, 5962-8763301XA trades retention for marginally lower cost and wider speed availability, while 5962-9213901MXA retains full functionality but sacrifices hermetic sealing - making 5962-8874001LA the sole choice for sealed, high-reliability airborne platforms.

FAQ
What is the maximum guaranteed access time for 5962-8874001LA across its full military temperature range?
The 5962-8874001LA has a maximum guaranteed access time (tAA) of 20ns over the full –55°C to +125°C operating temperature range, as specified in Renesas' official 2020 datasheet (Table 6.42, AC Electrical Characteristics). This value is production-tested and applies to both read and write setup timing under worst-case voltage (4.5V) and temperature conditions.
Does 5962-8874001LA support true data retention at 2V, and what is the current draw in that mode?
Yes, 5962-8874001LA supports guaranteed data retention at VCC = 2.0V, as confirmed in the "Data Retention Characteristics" table (Table 3089 tbl 10). At +125°C, ICCDR is ≤ 300µA; at +25°C, it is ≤ 20µA. This behavior is exclusive to the LA version and validated per MIL-STD-883 Method 1017.
Is 5962-8874001LA pin-compatible with commercial-grade IDT6116LA20 devices?
Yes, 5962-8874001LA shares identical pinout, function, and timing with commercial IDT6116LA20 variants (e.g., 6116LA20TDB), including A0–A10, I/O0–I/O7, CS, WE, OE, VCC, and GND assignments. However, 5962-8874001LA adds MIL-STD-883 Class B screening, hermetic SD24 packaging, and extended temperature validation - all without altering pin mapping or electrical interface.
What package type and lead finish does 5962-8874001LA use, and is it RoHS-compliant?
5962-8874001LA uses a 24-pin ceramic DIP (SD24) with tin-lead (SnPb) lead finish, compliant with MIL-STD-1835 and legacy military soldering standards. It is not RoHS-compliant due to Pb content; Renesas classifies it as a "green" part only in lead-free commercial variants (e.g., 6116LA20SOG), not in this 5962-8874001LA military specification.
How does the standby power consumption of 5962-8874001LA compare between TTL-level and CMOS-level chip select?
When CS is driven to TTL HIGH (>2.2V), 5962-8874001LA draws ISB ≤ 45mA (TTL-level standby). When CS exceeds VHC (VCC – 0.2V), it enters full CMOS standby with ISB1 ≤ 0.9mA - a 50× reduction enabling ultra-low-power hold modes in battery-backed subsystems. Both modes are characterized across –55°C to +125°C.
