DM74LS952, Dual Rank 8-Bit TRI-STATE?Shift Register
These circuits are TRI-STATE edge-triggered 8-bit I O registers in parallel with 8-bit serial shift registers which are capable of operating in any of the following modes parallel load from I O pins to register ‘‘A’’ parallel transfer down from register ‘‘A’’ to serial shift register ‘‘B’’ parallel
DM74LS952 Features
* Y Y Y Y Y Y Y Y Y Registers are edge-triggered by the positive transition of the clock All inputs are PNP transistors Input disable dominates over output disable Output high impedance state does not impede any other mode of operation 8-bit I O pins are TRI-STATE buffers Typical shift frequency is
