NXP HEF4027BT,653 触发器, 主/从, 互补输出, 正沿, JK, 30 ns, 30 MHz, 2.4 mA, SOIC, 16 引脚
The HEF4027BT is a dual JK Flip-flop features independent set-direct SD, clear-direct CD, clock inputs and outputs Q, Q\\. Data is accepted when clock is low and transferred to the output on the positive-going edge of the clock. The active high asynchronous clear-direct and set-direct inputs are independent and override the J, K and clock inputs. The outputs are buffered for best system performance. Schmitt trigger action makes the clock input highly tolerant of slower rise and fall times. It operates over a recommended VDD power supply range of 3 to 15V referenced to VSS usually ground. Unused inputs must be connected to VDD, VSS or another input.
