CD74HCT112 具有设置和复位功能的高速 CMOS 逻辑双路下降沿 J-K 触发器
The ’HC112 and ’HCT112 utilize silicon-gate CMOS technology to achieve operating speeds equivalent to LSTTL parts. They exhibit the low power consumption of standard CMOS integrated circuits, together with the ability to drive 10 LSTTL loads.
These flip-flops have independent J, K, Set, Reset, and Clock inputs and Q and Q\ outputs. They change state on the negative-going transition of the clock pulse. Set and Reset are accomplished asynchronously by low-level inputs.
The HCT logic family is functionally as well as pin-compatible with the standard LS logic family
