SN74LS323 - 8-BIT SHIFT/STORAGE REGISTER

Download the SN74LS323 datasheet PDF. This datasheet also covers the SN74LS323DW variant, as both devices belong to the same 8-bit shift/storage register family and are provided as variant models within a single manufacturer datasheet.

General Description

The logic diagram and truth table indicate the functional characteristics of the SN54/74LS323 Universal Shift/Storage Register.

This device is similar in operation to the SN54/74LS299 except for synchronous reset.

Key Features

  • are described below: 1. They use eight D-type edge-triggered flip-flops that respond only to the LOW-to-HIGH transition of the Clock (CP). The only timing restriction, therefore, is that the mode control (S0, S1) and data inputs (DS0, DS7, I/O0.
  • I/O7) may be stable at least a setup time prior to the positive transition of the Clock Pulse. 2. When S0 = S1 = 1, I/O0.
  • I/O7 are parallel inputs to flip-flops Q0.
  • Q7 respectively, and the outputs of Q0.
  • Q7 are in the high i.

8-BIT SHIFT/STORAGE REGISTER WITH 3-STATE OUTPUTS The SN54 / 74LS323 is an 8-Bit Universal Shift / Storage Register with 3-state outputs. Its function is similar to the SN54 / 74LS299 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 flip-flops 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.
