74VHC14

Hex Schmitt Inverter

General Description

Features

The VHC14 is an advanced high speed CMOS Hex

Schmitt Inverter fabricated with silicon gate CMOS tech-

nology. It achieves the high speed operation similar to

equivalent Bipolar Schottky TTL while maintaining the

CMOS low power dissipation. Pin configuration and func-

tion are the same as the VHC04 but the inputs have hys-

teresis between the positive-going and negative-going

input thresholds, which are capable of transforming

slowly changing input signals into sharply defined, jitter-

free output signals, thus providing greater noise margin

than conventional inverters.

• High Speed: t_PD= 5.5 ns (Typ.) at V_CC= 5 V

• Low Power Dissipation: I_CC= 2 μA (Max.) at T_A= 25°C

• High Noise Immunity: V_NIH= V_NIL= 28% V_CC(Min.)

• Power down protection is provided on all inputs

• Low Noise: V_OLP= 0.8 V (Max.)

• Pin and Function Compatible with 74HC14

An input protection circuit ensures that 0 V to 7 V can be

applied to the input pins without regard to the supply volt-

age. This device can be used to interface 5 V to 3 V sys-

tems and two supply systems such as battery back up.

This circuit prevents device destruction due to mis-

matched supply and input voltages.

Absolute Maximum Ratings⁽¹⁾

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

ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-

tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The

absolute maximum ratings are stress ratings only.

Note:

1. Absolute maximum ratings are values beyond which the device may be damaged or have its useful life impaired.

The data book specifications should be met, without exception, to ensure that the system design is reliable over its

power supply, temperature, and output/input loading variables. ON Semiconductor does not recommend operation

outside data-book specifications.

Recommended Operating Conditions⁽²⁾

The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended

operating conditions are specified to ensure optimal performance to the datasheet specifications. ON

Semiconductor does not recommend exceeding them or designing to absolute maximum ratings.
