DM74LS469 General Description

The ’LS469 is an 8-bit synchronous up/down counter with parallel load and hold capability. Three function-select inputs (LD, UD, CBI) provide one of four operations which occur synchronously on the rising edge of the clock (CK). The LOAD operation loads the inputs (D7 *D0) into the output reg.
