These devices are available in a variety of input/output configurations and multiple package options to meet a wide range of design requirements. Key Points Of Selection Counters Explore our portfolio of over 200 counter products, including synchronous and asynchronous, integrated up- and/or down-counters, rate multipliers, and frequency dividers. JK flip-flops Resolve common synchronous logic and memory issues such as synchronizing digital signals, converting momentary switches to toggle switches, or holding signals during reset with our portfolio of more than 40 JK flip-flops. Included are CMOS and TTL-compatible CMOS options. D-type flip-flops Resolve common synchronous logic and memory issues such as synchronizing digital signals, converting momentary switches to toggle switches, or holding signals during reset with our portfolio of more than 300 D-type flip-flops. Our portfolio includes Schmitt-trigger and 3-state device options available in 1-22 channel configurations. Other latches Resolve common asynchronous logic and memory issues such as enabling or disabling digital signals, holding signals during reset , or catch a digital pulse with our portfolio of more than 20 latches including addressable and SR-type latches. D-type latches Resolve common asynchronous logic and memory issues such as enabling or disabling digital signals or holding signals during reset with our portfolio of more than 180 D-type latches. Included are Schmitt-trigger and 3-state device options available in 1-32 channel configurations. Shift registers Resolve common I/O limitation issues such as increasing the number of inputs on a microcontroller or increasing the number of outputs on a microcontroller with our portfolio of more than 100 parallel-input, serial output and serial-input, parallel output shift registers.
