DESCRIPTION
The Am1402A, 3A, and 4A are 1024-bit silicon gate dynamic shift registers. The low threshold characteristics of this technology allow high-speed operation and DTL and TTL compatibility. The Am1402A is a quad 256-bit device; the Am1403A is a dual 512-bit register; and the Am1404A is a single 1024-bit. register. All three devices require two-phase non-overlapplng<clocks, and provide a one-bit shift on each clock pulse. Tt)e'Ar.02S02, 3, and 4 registers are functionally identical to the Am14D2A, 3A, and 4A, but are guaranteed to operate over freqvencies from 400 Hz to 10 MHz.
