74LV14

Hex inverting Schmitt trigger

Rev. 9 — 14 September 2021

Product data sheet

1. General description

The 74LV14 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC14

and 74HCT14.

The 74LV14 provides six inverting buffers with Schmitt-trigger input. It is capable of transforming

slowly-changing input signals into sharply defined, jitter-free output signals.

The inputs switch at different points for positive and negative-going signals. The difference between

the positive voltage V_T+and the negative voltage V_T-is defined as the input hysteresis voltage V_H.

2. Features and benefits

•

Wide supply voltage range from 1.0 V to 5.5 V

•

CMOS low power dissipation

Optimized for low voltage applications: 1.0 V to 3.6 V

Accepts TTL input levels between V_CC= 2.7 V and V_CC= 3.6 V

Typical output ground bounce < 0.8 V at V_CC= 3.3 V and T_amb= 25 °C

Typical HIGH-level output voltage (V_OH) undershoot: > 2 V at V_CC= 3.3 V and T_amb= 25 °C

Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

Complies with JEDEC standards:

•

JESD8-7 (1.65 V to 1.95 V)

JESD8-5 (2.3 V to 2.7 V)

JESD8C (2.7 V to 3.6 V)

JESD36 (4.5 V to 5.5 V)

•

ESD protection:

•

HBM JESD22-A114F exceeds 2000 V

MM JESD22-A115-A exceeds 200 V

•

Multiple package options

Specified from -40 °C to +85 °C and from -40 °C to +125 °C

3. Applications

•

Wave and pulse shapers for highly noisy environments

Astable multivibrators

Monostable multivibrators

13. Application information

The slow input rise and fall times cause additional power dissipation, this can be calculated using

the following formula:

P_add= f_i× (t_r× ΔI_CC(AV)+ t_f× ΔI_CC(AV)) × V_CCwhere:

P_add= additional power dissipation (μW);

f_i= input frequency (MHz);

t_r= rise time (ns); 10 % to 90 %;

t_f= fall time (ns); 90 % to 10 %;

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

Average ΔI_CC(AV)differs with positive or negative input transitions, as shown in Fig. 13.

An example of a relaxation circuit using the 74LV14 is shown in Fig. 14.
