Dual Positive Edge Triggered D-Type Flip-Flop 14-VQFN -40 to 125

16-bit edge-triggered D-type flip-flop with 3-state output 48-TSSOP -40 to 85

The high-performance silicon-gate CMOS MC74HCU04A has the same pin-out as the LS04 and MC14069UB. The device inputs are compatible with standard CMOS outputs; with pull-up resistors, they are compatible with LSTTL outputs. The device consists of six single-stage inverters. These inverters are ideal for use as oscillators, pulse shapers, and in many other applications requiring high input impedance amplifiers. For digital applications, the HC04A is recommended.

The MC74VHC1GT14 is a single gate CMOS Schmitt trigger inverter fabricated using a silicon gate CMOS process. It achieves high-speed operation similar to an equivalent bipolar Schottky TTL while maintaining CMOS low power consumption. The internal circuit consists of three stages, including a buffer output that provides high noise immunity and stable output. The device input is compatible with TTL-type input thresholds, and the output has a full CMOS level output swing. Input protection circuitry on the device allows overvoltage tolerance on the inputs, enabling the device to be used as a logic level translator from 3.0V CMOS logic to 5.0V CMOS logic, or 1.8V CMOS logic to 3.0V CMOS logic, and Capable of running on high voltage power supplies. The MC74VHC1GT14 input structure provides protection when voltages up to 5.5V are applied regardless of the supply voltage. This allows the MC74VHC1GT14 to be used as an interface to 5V to 3V circuits. The output structure also provides protection when VCC = 0V. These input and output structures help prevent device damage due to supply voltage - input/output voltage mismatch, battery backup, hot insertion, etc. The MC74VHC1GT14 can be used to enhance noise immunity or to square slowly changing waveforms.
