The MC100LVEL51 is a differentially clocked D-type flip-flop with reset. This device is functionally equivalent to the EL51 device, but operates from a 3.3V supply. With a propagation delay and output transition time comparable to the EL51, the LVEL51 is ideal for applications requiring the highest AC performance at 3.3V VCC. The reset input is an asynchronous, level-triggered signal. Data enters the master portion of the flip-flop when the clock is low, then transfers to the slave portion, and thus transfers to the output on a positive transition of the clock. The differential clock input of the LVEL51 supports the use of the device as a falling-edge triggered flip-flop. This differential input is clamped for stability under open-circuit input conditions. When left open, the CLK input will be pulled down to VEE and the CLKbar input will be biased at VCC/2.

The VHCT14A is an advanced high-speed CMOS six-way Schmitt inverter fabricated in silicon-gate CMOS technology. The VHCT14A consists of six independent inverters capable of converting slowly varying input signals into clearly defined, jitter-free output signals. A protection circuit ensures that 0V to 7V is applied to the input pin regardless of the supply voltage and the output pin at VCC = 0V. These circuits prevent device damage due to mismatched power supplies and input/output voltages. The device can be used as an interface between 3-V systems and 5-V systems as well as two power systems, such as battery backup.
