HYB514800BJ Datasheet, PDF (2/22 Pages) Siemens Semiconductor Group – 512kx8-Bit Dynamic RAM
HYB 514800BJ -60/-70/-80
512k x 8 DRAM
The HYB 514800BJ is the new generation dynamic RAM organized as 512 288 words by 8-bit. The
HYB 514800BJ utilizes CMOS silicon gate process as well as advances circuit techniques to
provide wide operation margins, both internally and for the system user. Multiplexed address inputs
permit the HYB 514800BJ to be packed in a standard plastic 400mil wide P-SOPJ-28 package. This
package size provides high system bit densities and is compatible with commonly used automatic
testing and insertion equipment. System oriented feature include single + 5 V (± 10 %) power
supply, direct interfacing with high performance logic device families such as Schottky TTL.
