Hex inverting Schmitt trigger

74HC14; 74HCT14

FEATURES

DESCRIPTION

• Applications:

The 74HC14 and 74HCT14 are high-speed Si-gate CMOS

devices and are pin compatible with low power Schottky

TTL (LSTTL). They are specified in compliance with

JEDEC standard no. 7A.

– Wave and pulse shapers

– Astable multivibrators

– Monostable multivibrators.

• Complies with JEDEC standard no. 7A

The 74HC14 and 74HCT14 provide six inverting buffers

with Schmitt-trigger action. They are capable of

transforming slowly changing input signals into sharply

defined, jitter-free output signals.

• ESD protection:

HBM EIA/JESD22-A114-A exceeds 2000 V

MM EIA/JESD22-A115-A exceeds 200 V.

• Specified from −40 to +85 °C and −40 to +125 °C.

Notes

1. C_PDis used to determine the dynamic power dissipation (P_Din µW):

P_D= C_PD× V_CC²× f_i× N + Σ(C_L× V_CC²× f_o) where:

f_i= input frequency in MHz;

f_o= output frequency in MHz;

C_L= output load capacitance in pF;

V_CC= supply voltage in Volts;

N = total load switching outputs;

Σ(C_L× V_CC²× f_o) = sum of the outputs.

2. For type 74HC14 the condition is V_I= GND to V_CC

.

For type 74HCT14 the condition is V_I= GND to V_CC− 1.5 V.

APPLICATION INFORMATION

The slow input rise and fall times cause additional power

dissipation. This can be calculated using the following

formula:

MNA852

400

handbook, halfpage

I

CC(AV)

(µA)

P_ad= f_i× (t_r× I_CC(AV)+ t_f× I_CC(AV)) × V_CC

.

300

Where:

P_ad= additional power dissipation (µW);

f_i= input frequency (MHz);

200

100

positive - going

edge

t_r= input rise time (µs); 10% to 90%;

t_f= input fall time (µs); 10% to 90%;

I_CC(AV)= average additional supply current (µA).

I_CC(AV)differs with positive or negative input transitions, as

shown in Figs 16 and 17.
