Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers

will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor

product management systems do not have the ability to manage part nomenclature that utilizes an underscore

(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain

device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated

device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

email any questions regarding the system integration to Fairchild_questions@onsemi.com.

74VHCT14A

Hex Schmitt Inverter

Features

General Description

■ High speed: t = 5.0ns (Typ.) at T = 25°C

The VHCT14A is an advanced high speed CMOS Hex

Schmitt Inverter fabricated with silicon gate CMOS

technology. The VHCT14A contains six independent

inverters which are capable of transforming slowly

changing input signals into sharply defined, jitter-free

output signals.

■ High noise immunity: V = 2.0V, V = 0.8V

■ Power down protection is provided on all inputs and

outputs

■ Low noise: V

= 1.0V (Max.)

OLP

■ Low power dissipation: I = 2µA (Max.) @ T = 25°C

Protection circuits ensure that 0V to 7V can be applied to

the input pins without regard to the supply voltage and

■ Pin and function compatible with 74HCT14

to the output pins with V = 0V. These circuits prevent

device destruction due to mismatched supply and

input/output voltages. This device can be used to inter-

face 3V to 5V systems and two supply systems such as

battery backup.

Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be

operable above the recommended operating conditions and stressing the parts to these levels is not recommended.

In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.

The absolute maximum ratings are stress ratings only.
