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).

Features/Benefits

■ 8-bit up/down counter for microprogram-counter, DMA controller and general-purpose counting applications

■ 8 bits matches byte boundaries

■ Bus-structured pinout

■ 24-pin SKINNYDIP saves space

■ 3-STATE outputs drive bus lines

■ Low current PNP inputs reduce loading

■ Expandable in 8-bit increments
