DM54LS469 DM54LS469/DM74LS469 8-Bit Up/Down Counter

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 regis.
