The CY74FCT191CTSOCT is a 4-bit up/down binary counter designed for synchronous counting and asynchronous presetting. It features a count enable input, terminal count output, and ripple-clock output, allowing for versatile implementation in various counting applications. The device operates with a typical output high voltage of 3.3 V and supports partial-power-down mode through its Ioff circuitry, which prevents backflow current when powered down. It is specified for a maximum output sink current of 64 mA and a source current of 32 mA. The counter is housed in a 16-pin SOIC package and is suitable for applications requiring reliable performance with improved noise characteristics due to its edge-rate control circuitry. ESD protection exceeds JESD 22 standards, ensuring robustness in handling.
