Product details
Overview
IDT6116LA45TPG from Integrated Device Technology is a 16K-bit (2K × 8) low-power CMOS static RAM with 45 ns access time, TTL-compatible I/O, and battery-backed data retention at 2 V. It operates across industrial temperature range (–45°C to +85°C), supports asynchronous read/write cycles without clocks or refresh, and is packaged in 24-pin plastic DIP (300 mil). Used in legacy industrial controllers requiring nonvolatile SRAM backup.
For engineers reviewing the IDT6116LA45TPG datasheet, IDT6116LA45TPG pinout, IDT6116LA45TPG application, or IDT6116LA45TPG equivalent, key selection criteria include standby current (≤20 µA at CMOS-level chip deselect), 2V data retention capability, 24-pin DIP footprint compatibility, and industrial-grade reliability per MIL-STD-883 Class B test compliance.
Technical Context
The IDT6116LA45TPG implements fully static asynchronous operation using high-reliability CMOS technology, eliminating need for clocks or refresh cycles. Its control logic uses independent Chip Select (CS), Output Enable (OE), and Write Enable (WE) signals to manage read/write/standby states via TTL-compatible voltage thresholds (VIH = 2.2 V min, VIL = 0.8 V max).
It features dual standby modes: TTL-level standby (ISB ≤ 20 mA) when CS > VIH, and ultra-low-power CMOS-level full standby (ISB1 ≤ 0.9 µA) when CS > VHC and inputs held valid. Data retention at 2 V is exclusive to LA versions and verified over full industrial temperature range.

|---|---|---|---|
| CY62167EV30LL-45ZSXIT | 512K × 16-bit, 3.3 V core, 45 ns access, SOIC-44 package | Higher density, lower voltage, surface-mount only - requires PCB redesign | Select only if migrating to 3.3 V systems and needing >16K capacity |
| AS6C1008-45ZIN | 128K × 8-bit, 5 V, 45 ns, 28-pin SOIC - no 2V retention or MIL-STD-883 qualification | Larger capacity but lacks battery backup and industrial reliability certification | Acceptable for cost-sensitive commercial designs where retention and ruggedness are secondary |
Compared with IDT6116LA45TPG, CY62167EV30LL-45ZSXIT offers higher density and modern packaging but mandates voltage and layout changes, while AS6C1008-45ZIN provides greater capacity at same speed yet omits critical industrial features: 2V data retention, ultra-low ISB1, and MIL-STD-883 Class B validation.

FAQ
What is the guaranteed data retention voltage for IDT6116LA45TPG?
IDT6116LA45TPG guarantees data retention down to 2.0 V (VDR = 2.0 V), as specified in Table 10 of the datasheet. This allows direct connection to common 2 V lithium backup cells without regulation. The retention current (ICCDR) remains ≤1.5 µA across the full industrial temperature range (–45°C to +85°C), ensuring multi-year operation on small batteries.
Does IDT6116LA45TPG require a clock signal or refresh cycle?
No, IDT6116LA45TPG is a fully static RAM and requires neither clock signals nor periodic refresh cycles. Its internal circuitry maintains data indefinitely as long as VCC and backup voltage (if used) remain within specification. This simplifies system design by eliminating timing-critical refresh overhead in microcontroller or FPGA-based systems.
What is the maximum operating current of IDT6116LA45TPG during active read cycles?
IDT6116LA45TPG draws up to 75 mA (ICC1) during active read operations at VCC = 5.5 V and f = 0, per Table 8. Under dynamic conditions at maximum frequency (fMAX = 1/tRC ≈ 22.2 MHz), ICC2 reaches 90 mA. These values are measured with all outputs open and reflect worst-case commercial/industrial grade performance.
Is IDT6116LA45TPG pin-compatible with other IDT6116 variants?
Yes, IDT6116LA45TPG shares identical 24-pin DIP (P24-1) pinout and signal definitions with all IDT6116SA/LA family members, including IDT6116LA25TPG and IDT6116SA45TPG. Address, data, control pins, and power terminals are functionally and physically identical - enabling drop-in replacement where speed and power requirements align.
What packaging and temperature grade does IDT6116LA45TPG use?
IDT6116LA45TPG uses a 24-pin plastic DIP (300 mil, P24-1) package and is rated for the industrial temperature range (–45°C to +85°C), as indicated by the "I" suffix in its ordering code. It is manufactured and tested to MIL-STD-883 Class B standards, confirming reliability for harsh-environment applications despite its industrial grade designation.
