产品概述
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
