The VHC112 is an advanced high-speed CMOS inverter fabricated in silicon-gate CMOS technology. It achieves high-speed operation similar to the equivalent bipolar Schottky TTL while maintaining low power consumption in CMOS. The VHC112 contains two independent high-speed JK flip-flops with direction set and clear inputs. A synchronous state change is initiated by the falling edge of the clock. Triggering occurs at a certain level of the clock and is not directly related to the conversion time. The J and K inputs can change at either state of the clock without affecting the flip-flop, provided the values ​​are at the recommended settings and hold time requirements relative to the falling edge of the clock. A low signal on PR or CLR prevents clocking, forcing Q and Q# high, respectively. A simultaneous low on PR and CLR forces both Q and Q# high. Input protection circuitry ensures that 0V to 7V can be applied to the input pins regardless of supply voltage. This device can be used to interface 5V to 3V systems and two power systems such as backup batteries. This circuit prevents damage to the device due to mismatch between power supply and input voltage.
