Product details
Overview
IDT71V416VL10PH8 from Integrated Device Technology is a 4-Mbit (256K × 16) high-speed CMOS static RAM with 10 ns access time, single 3.3 V supply operation, and LVTTL-compatible I/O. It features separate byte enable (BHE/BLE), output enable (OE), and chip select (CS) for flexible memory mapping in embedded controllers and industrial data acquisition systems.
For engineers reviewing the IDT71V416VL10PH8 datasheet, IDT71V416VL10PH8 pinout, IDT71V416VL10PH8 application, or IDT71V416VL10PH8 equivalent, this device supports fast asynchronous read/write cycles, low-power standby modes, JEDEC-compliant noise-reduced pinout, and dual-byte write control - critical for real-time buffering and firmware storage in space-constrained industrial designs.
Technical Context
The IDT71V416VL10PH8 implements fully static asynchronous circuitry with no clocks or refresh required. Its address decoding supports A0–A17 (18-bit addressing), enabling direct 256K-word access without external logic. The device uses bidirectional LVTTL I/O buffers with guaranteed 5 ns OE-to-valid timing and 4 ns CS-to-output-low-Z delay.
It integrates independent high- and low-byte write enables (BHE/BLE), allowing partial-word writes without bus contention. Power management includes three distinct current states: dynamic operating (≤200 mA), dynamic standby (≤70 mA), and full static standby (≤20 mA), all specified across industrial temperature range (–40°C to +85°C).

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress CY7C1041DV33-10ZSXI | Same 256K × 16 density, 10 ns speed, and 44-pin TSOP-II package; higher ICC (220 mA) and no BHE/BLE pins | Lacks byte-enable control - requires external logic for partial-word writes; better suited for simple cache or frame buffer use | Select when board layout uses TSOP-II and byte masking is handled in controller firmware |
| ISSI IS61LV25616AL-10TLI | Identical SOJ-44 footprint and pinout; same 10 ns access but only commercial temp range (0°C to +70°C); lower ISB1 (10 mA) | Not rated for industrial environments - unsuitable for factory-floor deployments without thermal derating | Select for cost-sensitive commercial systems where ambient temperature remains below 70°C and full industrial qualification is unnecessary |
Compared with IDT71V416VL10PH8, CY7C1041DV33-10ZSXI offers higher drive strength but sacrifices byte-level write control, while IS61LV25616AL-10TLI matches mechanical compatibility but lacks industrial temperature validation - making IDT71V416VL10PH8 the only option meeting both SOJ-44 form factor and –40°C to +85°C operational reliability.

FAQ
What is the operating temperature range for IDT71V416VL10PH8?
IDT71V416VL10PH8 is rated for industrial temperature operation from –40°C to +85°C. This specification is validated across all AC and DC parameters in the datasheet, including access time, power consumption, and leakage current. The "I" grade designation in the part number confirms this industrial qualification, making IDT71V416VL10PH8 suitable for deployment in harsh environments such as factory automation and outdoor control cabinets.
Does IDT71V416VL10PH8 require a clock or refresh signal?
No, IDT71V416VL10PH8 uses fully static asynchronous circuitry and requires no clock, refresh, or wait-state signals. All operations are controlled solely by address, CS, OE, WE, and byte enable inputs. This eliminates timing complexity in microcontroller-based designs and avoids refresh-related power spikes - a key advantage over DRAM or pseudo-static RAM alternatives.
What package type does IDT71V416VL10PH8 use?
IDT71V416VL10PH8 uses a 44-pin, 400-mil plastic SOJ (Small Outline J-lead) package, designated by the "PH" suffix in the part number. This JEDEC-standard package features center-placed VDD/VSS pins to reduce ground bounce and is compatible with standard reflow soldering profiles used in industrial PCB assembly.
Can IDT71V416VL10PH8 perform byte-wide writes?
Yes, IDT71V416VL10PH8 supports true byte-wide writes via dedicated BHE (high byte enable) and BLE (low byte enable) pins. When only one byte enable is asserted low with WE active, only the corresponding 8-bit portion of I/O0–I/O15 is written - enabling efficient partial-word updates without read-modify-write sequences or external logic.
What is the maximum supply voltage tolerance for IDT71V416VL10PH8?
IDT71V416VL10PH8 operates within a supply voltage range of 3.0 V to 3.6 V, with absolute maximum rating of –0.5 V to +4.6 V on VDD relative to VSS. Sustained operation above 3.6 V risks parametric shift or long-term reliability degradation; therefore, proper regulation to ≤3.6 V is required in all designs using IDT71V416VL10PH8.
