UT62256B

The UT62256B is a kind of 32K*8 bit low power CMOS SRAM. It is designed for high-speed and low power applications. Besides,its all inputs and outputs are fully TTL compatible. It is available in 28-pin 330 mil SOP package.

There are some features of the UT62256B as follows. (1) access time which is 35 ns; (2) low operating consumption which is 45 mA; (3) single 5 V power supply; (4) fully static operation; (5) three state outputs; (6) data retention voltage which is 2 V.

What comes next is some information about the absolute maximum ratings of the UT62256B. (1): terminal voltage with respect to VSS (VTERM) is from -0.5 V to 7.0 V; (2): operating temperature (TA) is from 0 to 70 ; (3): storage temperature (Tstg) is from -65 to 150 ; (4): power dissipation (PD) is 1 W; (5): DC output current (IOUT) is 50 mA; (6): soldering temperature(under 10 sec) is 260 . Then is about its DC electrical characteristics at VCC is 5.0 V±10 % and TA is from 0 to 70 . (1):  input high voltage (VIH) is from 2.2 V to VCC+0.5 V; (2): input low voltage (VIL) is from -0.5 V to 0.8 V; (3): input leakage current (ILI) is from -1 A to 1 A; (4): the maximum standby power is 3 mA.
