产品概述
The SN74HC4040PWR 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.
- Outputs can drive up to 10 LSTTL loads
- 80µA Maximum low power consumption
- 12ns Typical tpd
- ±4mA Output drive at 5V
- 1µA Maximum low input current
- Green product and no Sb/Br
