DATASHEET
The Intel 512 bit dynamic recirculating shift register consists of normally off P-channel MOS devices integrated on a monolithic chip. The use of low voltage circuitry minimizes power dissipation and
facilitates interfacing with bipolar integrated circuits. These registers can be driven directly by standard bipolar integrated circuits (TTL, DTL, etc.) or by MOS circuits. The design of the output stage provides driving capability for both MOS and bipolar IC’s as well as OR-tieing of soft registers. Use of low threshold silicon gate technology allows high speed (2 MHz guaranteed) while reducing power dissipation by a factor of two and clock input capacitance by a factor of three compared to equivalent products manufactured by conventional technologies.
The 1405 is designed for low cost memory and delay line applications. Write/Recirculate and read controls eliminate the need for external logic elements when recirculating data. In addition, any number of devices can be combined to form a multi-dimensional memory array. For this purpose two chip select controls have been provided [1].
