FEATURES DUAL 640 BIT o ADDITIONAL TAPS AT 512 ON EACH REGISTER INTERNAL CLOCKING o HIGH SPEED 3 STATE OUTPUT BUFFER APPLICATIONS CRT DISPLAYS COMPUTER PERIPHERALS CRYPTOGRAPHY GENERAL DESCRIPTION The WD5869 Dual 640 Bit Dynamic Shift Register is a monolithic MOS integrated circuit designed for use in computer display peripherals.
The clocks and recirculate logic are internal to reduce system component count, and 3 state output buffers provide bus interface.
The WD5869 is available in a 16 pin molded plastic package, or a 16 pin ceramic package.
