The P2114AL4 is a 4Kbit asynchronous SRAM organized as 1K x 4 bits, in a through-hole 18-DIP package. It runs on a 4.5 V to 5.5 V supply and delivers a 200 ns access time.
200 ns is the read-access and write-cycle time. The write cycle time (200 ns) matches the read, so there is no asymmetry penalty.
There is no pin-compatible second source or official replacement listed for the P2114AL4. The N28F512200 is a 512Kbit Flash memory in a surface-mount package — different technology, footprint, and voltage range; it is not a functional equivalent.
The operating temperature range is -55 °C to 125 °C (TA), which is the full military temperature grade. Storage temperature is not separately specified in the listing.
