ONSEMI MC74VHCT14A

SEMICONDUCTOR TECHNICAL DATA
The MC74VHCT14A is an advanced high speed CMOS Schmitt inverter
fabricated with silicon gate CMOS technology. It achieves high speed
operation similar to equivalent Bipolar Schottky TTL while maintaining
CMOS low power dissipation.
Pin configuration and function are the same as the MC74VHCT04A, but
the inputs have hysteresis and, with its Schmitt trigger function, the
VHCT14A can be used as a line receiver which will receive slow input
signals.
The VHCT inputs are compatible with TTL levels. This device can be used
as a level converter for interfacing 3.3V to 5.0V, because it has full 5V CMOS
level output swings.
The VHCT14A input structures provide protection when voltages between
0V and 5.5V are applied, regardless of the supply voltage. The output
structures also provide protection when VCC = 0V. These input and output
structures help prevent device destruction caused by supply voltage –
input/output voltage mismatch, battery backup, hot insertion, etc.
The internal circuit is composed of three stages, including a buffer output
which provides high noise immunity and stable output. The inputs tolerate
voltages up to 7V, allowing the interface of 5V systems to 3V systems.

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high–impedance circuit. For proper operation, Vin and
Vout should be constrained to the
range GND (Vin or Vout) VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or V CC ).
Unused outputs must be left open.

* Absolute maximum continuous ratings are those values beyond which damage to the device may occur. Exposure to these conditions or conditions
beyond those indicated may adversely affect device reliability. Functional operation under absolute–maximum–rated conditions is not implied.

1. CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load.
Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC / 6 (per buffer). CPD is used to determine the no–load
dynamic power consumption; PD = CPD VCC2 fin + ICC VCC.
