High–Performance Silicon–Gate CMOS

The MC54/74HCT14A may be used as a level converter for interfacing

TTL or NMOS outputs to high–speed CMOS inputs.

The HCT14A is identical in pinout to the LS14.

The HCT14A is useful to “square up” slow input rise and fall times. Due to
the hysteresis voltage of the Schmitt trigger, the HCT14A finds applications
in noisy environments.

• Output Drive Capability: 10 LSTTL Loads

• TTL/NMOS–Compatible Input Levels

• Outputs Directly Interface to CMOS, NMOS and TTL

• Operating Voltage Range: 4.5 to 5.5 V

• Low Input Current: 1.0 µA

• In Compliance with the Requirements Defined by JEDEC Standard

No. 7A

• Chip Complexity: 72 FETs or 18 Equivalent Gates

NOTE: Information on typical parametric values can be found in Chapter 2 of the Motorola High–Speed CMOS Data Book (DL129/D).

(continued)

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
V

out

should be constrained to the

range GND v (Vin or V

out

) v VCC.

Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
