Description
The 74LS193DR2 is an electronic component model in the product category of IC chips. It is a presettable BCD/decade up/down counter and a 4-bit binary up/down counter. The circuit operates synchronously with separate count up and count down clocks. The outputs change state synchronous with the LOW-to-HIGH transitions on the clock inputs. The 74LS193DR2 also provides separate terminal count up and terminal count down outputs, allowing for easy integration into multistage counter designs. It has individual preset inputs and features both asynchronous master reset and parallel load functionality. The 74LS193DR2 is a low power component with typical dissipation of 95 mW and a high-speed count frequency of 40 MHz. It supports synchronous counting and includes input clamp diodes to limit high-speed termination effects.Specifications and features
