DM74LS323 Datasheet | National Semiconductor

Description The ’LS323 is an 8-bit universal shift storage register with TRI-STATE outputs Its function is similar to the ’LS299 with the exception of Synchronous Reset Parallel load inputs and flip-flop outputs are multiplexed to minimize pin count Separate inputs and outputs are provided for flipflops Q0 and Q7 to allow easy cascading Four operation modes are possible hold (store) shift left shift right and parallel load All modes are activated on the LOW-to-HIGH transition of the Clock Features Y Y mon I O for reduced pin count Four operation modes shift left shift right parallel load and store Separate continuous inputs and outputs from Q0 and Q7 allow easy cascading Fully synchronous reset TRI-STATE outputs for bus oriented applications Connection Diagram Dual-In-Line Package TL F 9829 - 1 Order Number DM54LS323J DM54LS323W DM74LS323WM or DM74LS323N See NS Package Number J20A M20B N20A or W20A Pin Names CP DS0 DS7 S0 S1 SR OE1 OE2 I O0- I O7 Q0 Q7 Description Clock Pulse Input (Active Rising Edge) Serial Data Input for Right Shift Serial Data Input for Left Shift Mode Select Inputs Synchronous Reset Input (Active LOW) TRI-STATE Output Enable Inputs (Active LOW) Parallel Data Inputs or TRI-STATE Parallel Outputs Serial Outputs TRI-STATE is a registered trademark of National Semiconductor Corporation C1995 National Semiconductor Corporation TL F 9829 RRD-B30M115 Printed in U S A Absolute Maximum Ratings (Note) If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Supply Voltage 7V Input Voltage 7V Operating Free Air Temperature Range b 55 C to a 125 C DM54LS DM74LS 0 C to a 70 C b 65 C to a 150 C Storage Temperature Range Note The ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed The device should not be operated at these limits The parametric values defined in the ‘‘Electrical...
