SN74LS323

The SN74LS323 is designed as an 8-bit universal shift/storage Register with 3-state outputs.

SN74LS323 has seven features. (1)Common I/O for reduced pin count. (2)Four operation modes: shift left, shift right, parallel load and store. (3)Separate continuous inputs and outputs from Q0 and Q7 allow easy cascading. (4)Fully synchronous reset. (5)3-state outputs for bus oriented applications. (6)Input clamp diodes limit high-speed termination effects. (7)ESD is larger than 3500 volts. Those are all the main features.
