Логическая ИС SN74LV4040APWR

Двоичный асинхронный счетчик , семейство LV, 185МГц, 2В - 5.5В, TSSOP-16

The SN74LV4040APWR is a 12-bit Asynchronous Binary Counter with the outputs of all stages available externally. A high level at the clear (CLR) input asynchronously clears the counter and resets all outputs low. The count is advanced on a high-to-low transition at the clock input. Applications include time-delay circuits, counter controls and frequency-dividing circuits. It is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down.

• Supports mixed-mode voltage operation on all ports
• High on-OFF output-voltage ratio
• Low crosstalk between switches
• Individual switch controls
• Extremely low input current
• Ioff Supports partial-power-down mode operation
• Latch-up performance exceeds 100mA per JESD 78, class II
• Green product and no Sb/Br
