DATASHEET
AT91R40008-66AU 描述
A negative switch is a device where both the operate and release points are less than zero gauss (negative values). In the configuration shown in Figure 3, such a device will switch OFF and then switch ON on the trailing or falling edge of the target tooth (Figure 4 (b)).
AT91R40008-66AU 特点
The clear function for the HC163 devices is synchronous. A low level at the clear (CLR) input sets all four of the flip-flop outputs low after the next low-to-high transition of CLK, regardless of the levels of the enable inputs. This synchronous clear allows the count length to be modified easily by decoding the Q outputs for the maximum count desired. The active-low output of the gate used for decoding is connected to CLR to synchronously clear the counter to 0000 (LLLL).
