Product details
Overview
IDT6116SA25TP from Integrated Device Technology is a 16K-bit (2K × 8) high-speed CMOS static RAM with 25 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 full static asynchronous operation (no clock or refresh), and features dual standby modes - TTL-level (ISB = 40 mA max) and CMOS-level (ISB1 = 2 mA max) - for system power optimization in embedded controllers and data acquisition systems.
For engineers reviewing the IDT6116SA25TP datasheet, IDT6116SA25TP pinout, IDT6116SA25TP application, or IDT6116SA25TP equivalent, key selection criteria include guaranteed 25 ns read cycle time (tRC), chip-select–controlled low-power standby, 24-pin SOIC packaging, and compatibility with legacy 2K×8 SRAM-based memory interfaces in avionics, test equipment, and industrial PLCs.
Technical Context
The IDT6116SA25TP implements a fully static 128 × 128 memory array with asynchronous address decoding and I/O control circuitry. Its operation requires no clocks or refresh cycles, and it uses standard TTL voltage thresholds (VIH = 2.2 V min, VIL = 0.8 V max) for seamless integration with microcontroller buses.
Two distinct standby modes are supported: ISB (TTL-level CS > VIH) draws ≤40 mA, while ISB1 (CMOS-level CS > VHC with VIN < VLC or > VHC) reduces current to ≤2 mA. Write operations are controlled via independent WE and OE signals, with tWP = 15 ns minimum and tDW = 13 ns data-to-write overlap required.
Key Specifications

| CY62167EV30LL-45ZSXI | 32K × 8-bit, 45 ns access, 3.3 V core (5 V tolerant I/O), SOIC-28 | Higher density, lower voltage, larger package - requires PCB redesign and level-shifting | Select only if upgrading capacity and migrating to 3.3 V systems; not pin-compatible with IDT6116SA25TP |
| AS6C1008-25PCN | 128K × 8-bit, 25 ns access, 5 V, 28-pin SOIC, higher ICC1 (35 mA vs. 80 mA) | Same speed grade but 8× capacity and different pin count - incompatible pinout and address mapping | Use only for new designs needing expanded memory; requires firmware and layout changes |

FAQ
What is the maximum operating temperature range for the IDT6116SA25TP?
The IDT6116SA25TP is rated for industrial temperature operation from –45°C to +85°C, as confirmed in the official IDT datasheet (DSC-3089/03, February 2001). This range is explicitly defined under "Recommended Operating Temperature and Supply Voltage" and validated per IDT's industrial qualification standards - not extrapolated or derived from military-grade variants.
Does the IDT6116SA25TP require a refresh signal or clock input?
No, the IDT6116SA25TP is a fully static RAM and requires no refresh signal or clock input. Its internal circuitry is asynchronous and self-timed, relying solely on address, CS, WE, and OE transitions. This is stated in the "Description" section and reinforced by the "Static operation: no clocks or refresh required" feature bullet in the datasheet.
What is the pin-compatible replacement for IDT6116SA25TP in 24-pin SOIC?
No documented pin-compatible replacement exists for the IDT6116SA25TP in 24-pin SOIC. While other 2K×8 SRAMs (e.g., AS6C62256-25PCN) share functional equivalence, they differ in pinout, timing parameters, or package dimensions. The IDT6116SA25TP remains the only part with verified 24-pin SOIC (SO24-2) pin alignment and identical 2K×8 organization among IDT's documented offerings.
What is the standby current specification for IDT6116SA25TP under CMOS-level chip select?
Under CMOS-level chip select (CS > VHC, VIN < VLC or > VHC, f = 0), the IDT6116SA25TP draws ≤2 mA (ISB1), as specified in Table 8 of the datasheet for the SA speed grade. This value is measured at VCC = max (5.5 V) and represents full standby - distinct from the higher 40 mA ISB (TTL-level) mode.
Is the IDT6116SA25TP compliant with RoHS or lead-free requirements?
The IDT6116SA25TP datasheet (DSC-3089/03, 2001) predates RoHS legislation and does not specify lead-free or RoHS compliance. As a legacy industrial-grade part manufactured prior to 2006, it is not RoHS-compliant unless explicitly requalified and marked by a certified distributor. Aetrix Electronics provides traceable lot data upon request for legacy compliance verification.
