74LS194A Datasheet | Motorola Semiconductor

features of shift left without external connections and hold (do nothing) modes of operation. It utilizes the Schottky diode clamped process to achieve high speeds and is fully patible with all Motorola TTL families. - Typical Shift Frequency of 36 MHz - Asynchronous Master Reset - Hold (Do Nothing) Mode - Fully Synchronous Serial or Parallel Data Transfers - Input Clamp Diodes Limit High Speed Termination Effects CONNECTION DIAGRAM DIP (TOP VIEW) VCC Q0 Q1 Q2 Q3 CP S1 S0 16 15 14 13 12 11 10 9 MR DSR P0 P1 P2 P3 DSL GND PIN NAMES LOADING (Note a) HIGH S0, S1 P0 - P3 DSR DSL CP Q0 - Q3 Mode Control Inputs Parallel Data Inputs Serial (Shift Right) Data Input Serial (Shift Left) Data Input Clock (Active HIGH Going Edge) Input Master Reset (Active LOW) Input Parallel Outputs (Note b) 0.5 U.L. 0.5 U.L. 0.5 U.L. 0.5 U.L. 0.5 U.L. 0.5 U.L. 10 U.L. 0.25 U.L. 0.25 U.L. 0.25 U.L. 0.25 U.L. 0.25 U.L. 0.25 U.L. 5 (2.5) U.L.
