1 / 10 page  1 Document # SRAM109 REV A Revised October 2005 P4C1681, P4C1682 ULTRA HIGH SPEED 4K x 4 STATIC CMOS RAMS FEATURES Full CMOS, 6T Cell High Speed (Equal Access and Cycle Times) – 12/15/20/25 ns (Commercial) – 20/25/35ns (Military) Low Power Operation Single 5V ± 10%Power Supply Separate Inputs and Outputs – P4C1681 Input Data at Outputs during Write – P4C1682 Outputs in High Z during Write Fully TTL Compatible Inputs and Outputs Standard Pinout (JEDEC Approved) – 24-Pin 300 mil DIP – 24-Pin 300 mil SOIC – 24-Pin 300 mil SOJ – 24-Pin Solder Seal Flat Pack – 28-Pin LCC (450 mil x 450 mil) . DESCRIPTION The P4C1681 and P4C1682 are 16,384-bit (4K x 4) ultra high speed static RAMs similar to the P4C168, but with separate data I/O pins. The P4C1681 features a transparent write operation; the outputs of the P4C1682 are in high impedance during the write cycle. All devices have low power standby modes. The RAMs operate from a single 5V ± 10% tolerance power supply. Access times as fast as 12 nanoseconds are available, permitting greatly enhanced system operating speeds. CMOS is used to reduce power consumption. TheP4C1681andP4C1682areavailablein24-pin300mil DIP, SOIC, Solder Seal Flatpack, and SOJ packages, as well as a 28-pin LCC package, providing excellent board level densities.
