74LVC14APWDH

Hex inverting Schmitt-trigger with 5V tolerant input

Philips Electronics 

Philips Semiconductors

Hex inverting Schmitt-trigger with 5V

tolerant input

Product specification

74LVC14A

FEATURES

• Wide supply voltage range of: 1.2 V to 3.6 V

• In accordance with JEDEC standard no. 8-1A

• Inputs accept voltages up to 5.5 V

• CMOS low power consumption

• Direct interface with TTL levels

APPLICATIONS

• Wave and pulse shapers for highly noisy environments

• Astable multivibrators

• Monostable multivibrators

DESCRIPTION

The 74LVC14A is a high-performance, low power, low-voltage

Si-gate CMOS device and superior to most advanced CMOS

compatible TTL families.

Inputs can be driven from either 3.3 V or 5 V devices. This feature

allows the use of these devices as translators in a mixed 3.3 V/5 V

environment.

The 74LVC14A provides six inverting buffers with Schmitt-trigger

action. It is capable of transforming slowly changing input signals

into sharply defined, jitter-free output signals.

CPD

Power dissipation capacitance per gate Notes 1 and 2

NOTES:

1. CPD is used to determine the dynamic power dissipation (PD in µW)

PD = CPD × VCC2 × fi )ȍ (CL × VCC2 × fo) where:

fi = input frequency in MHz; CL = output load capacity in pF;

fo = output frequency in MHz; VCC = supply voltage in V;

ȍ (CL × VCC2 × fo) = sum of the outputs.

2. The condition is VI = GND to VCC.
